In its drive for innovative solutions to problematic component wear and friction, Applied Nano Surfaces has expanded its North America footprint through a technology development and production partnership with Precision Finishing, Inc.

Uppsala Sweden, November 5, 2021.

Applied Nano Surfaces (ANS) has entered a strategic partnership with Precision Finishing Inc., to advance a unique variant of its core Triboconditioning® technology, which is a patented process developed to provide for friction reduction and wear resistance on various steel and cast-iron surfaces. The new variant, known as Triboconditioning® CG (Complex Geometries), is a mechanochemical surface treatment process specifically engineered to address the outer complex geometries of components such as gears. Additional benefits of this treatment include improved surface finish and running in behavior, noise reduction (NVH), minimization and improvement for scuffing, pitting, rolling fatigue resistance as well as extending the product service life.

This partnership brings together the knowledge and expertise of the ANS friction/wear reduction treatment technologies along with the highest-level of mechanical surface finishing processes and functional part optimization from Precision Finishing Inc.

“The synergy and combined expertise of our two companies will effectively service the quickly evolving market that is seeking solutions to enhance component value by increasing life along with minimizing friction, noise and other inherent issues such as pitting and scuffing” said David Chobany, Technology and Sales Director – Americas for Applied Nano Surfaces

The partnership of ANS with Precision Finishing Inc. marks an exciting jumping off point for the North American market. “The group at ANS is wonderful to work with and very knowledgeable. Triboconditioning® CG is an exciting process and it is very synergistic with our business model.

Technologies from Sigma Materials and Applied Nano Surfaces prevent abrasion of potentially hazardous particles in road and rail traffic

Applied Nano Surfaces, Erkrath in Nordrhein-Westfalen, March 2021

Particulate matter produced by the operation of motor vehicles is indisputably a potential health hazard. Tougher exhaust standards and the use of modern particulate filters have effectively reduced emissions from internal combustion engines, and with increasing e-mobility, fewer exhaust pollutants are being released into the environment. What remains is particulate pollution from the abrasion of tyres and brakes in road and rail traffic. With technologies from Sigma Materials and Applied Nano Surfaces, at least brake dust emissions can be sustainably reduced.

 

When cars stop at traffic lights or a train stops at the platform, the brakes have to cope with enormous loads. As sophisticated as modern braking systems have become, however, most systems are still based on discs made of grey cast iron, which wear out through abrasion and have to be replaced regularly. In the past, this was more or less taken note of and hardly anyone paid attention to the question of where the abraded metal particles ultimately remain.

 

Growing awareness of the problem and modern analysis technology draw increased attention to brake discs and brake dust

However, with advances in analytical technology and a growing awareness of the potential health hazards of particulate matter, brake abrasion is now coming more and more into focus. The attention of environmental researchers and health experts is focused in particular on particles with a diameter of less than 10 micrometres, officially referred to as “fine dust”, and even more so on particles with diameters below 2.5 micrometres, which can penetrate deep into the respiratory tract and cause lasting damage to the lungs and other organs. It is now clear that brake abrasion contains a high proportion of such particles. The State Institute for the Environment, Measurements and Nature Conservation Baden-Württemberg (LUBW) puts the annual brake dust emission for Germany from road traffic alone at 14,000 tonnes. As if that were not enough, brake dust contains particles of metals such as copper, iron or even antimony, which in turn can cause damage to health, the extent of which is still largely unexplored. Meanwhile, brake dust continues to be deposited along roads and railways, is stirred up as vehicles pass by and enters the air we breathe everywhere in densely populated areas.

 

Brake abrasion reduced to an absolute minimum: Tribo-conditioning and alternative materials make it possible

Wherever the principle of a disc brake is used, the abrasion of the finest particles can hardly be completely prevented: The braking process releases mechanical forces on the surface of the discs and generates heat, and friction repeatedly tears individual particles out of the material structures. However, the extent of the abrasion can be influenced, for example by coating the basic metal structure with wear-resistant materials such as tungsten carbide. With the triboconditioning developed by Applied Nano Surfaces (ANS), brake abrasion can be reduced even further: In this process, the brake discs are treated in a special surface finishing process in such a way that a “tribofilm” chemically bonds with the disc material and drastically reduces the abrasion of individual particles even under high material loads. As a result, not only is there less brake dust, but the durability of the brake discs is also increased several times over. However, this only works if the brake discs are made of special materials.

 

MMC: wear-resistant, temperature-resistant and lightweight

A technology developed by ANS partner company Sigma Materials is suitable for manufacturing such products. Sigma Materials uses so-called metal matrix composite (MMC) alloys with aluminium and/or titanium as a basis, which are enriched with particles and fibres from other materials depending on the application or to improve strength. As metal-matrix composites (MMC), the alloys go through a special manufacturing process: the material mixture is compacted by direct pressure sintering. The use of this type of sintering – i.e. pressing the powder together under high pressure and at temperatures close to the melting point – results in the ingredients bonding together extremely densely and homogeneously, with no residual porosity either on the outside or inside.

 

95 percent less particle emission and temperature resistant up to 800°C

When used as a brake disc, Sigma Materials reinforces the friction surfaces of the MMC product with special and particularly hard substances. On contact with the adapted brake pad, this structure ensures the formation of a fine transfer film between the contacting surfaces, which additionally reduces material wear. Although brake discs made of light metal are nothing new per se, such brake discs can only withstand temperatures of up to the order of 450°C and can therefore only be used as an alternative to classic grey cast iron products to a limited extent. The special MMC brake discs manufactured by Sigma Materials, on the other hand, can even be integrated into front axle brakes in which temperatures of up to 700°C can be generated during the braking process. And compared to conventional brake discs made of grey cast iron, the particle emission of MMC products is even up to 95 percent lower.

 

„Increasing electromobility only partly solves the brake dust problem“

For Andreas Storz, Managing Director of Applied Nano Surfaces GmbH and owner of Sigma Materials GmbH, tribo-conditioning and MMC-based products are currently the most suitable solution for getting the still acute brake dust problem under control in the long term. “In the current discussion about the expansion of electromobility, it is easy to get the impression that the occurrence of brake dust will virtually take care of itself over time thanks to recuperation,” says Storz, a mechanical engineer. “In reality, however, cars are getting bigger and heavier, which ultimately leads to higher loads on the brake discs and does not really reduce particle emissions, despite the recovery of braking energy via electric motors. Moreover, only part of the braking energy can ever be “saved”, and by not using the discs in everyday life due to recuperation, disc rust is a huge problem.” Apart from that, the brake dust emitted in road traffic also represents only a part of the total pollution, he said. “At the moment, it is not even possible to roughly estimate what brake dust is produced in freight traffic above ground on the railways or in passenger transport in the underground and is permanently swirled in the air along the tracks,” Andreas Storz points out, “and even if there are even brake dust filters in the meantime which add weight and service cost, the toxic residues still have to remain somewhere.”

Classic brake discs made of grey cast iron (painted silver in the photo in the background) release finest metal particles through abrasion, which pollute the environment as fine dust. The ANS tribo-conditioning (light grey surface of the segment in the foreground), on the other hand, enables an almost wear-free braking system. The segment shows the innovative material concept (dark MMC layers on a conventional aluminium carrier layer in the middle).

 

 

 

 

 

 

 

 

With the help of MMC technology from Sigma Materials, extremely compact and highly resilient composite materials can be created. The light areas on the micrograph consist of an aluminium-titanium matrix, while the dark spots are ceramic hard particles. While conventional aluminium alloys typically melt at 560°C, this material remains stable up to over 1,000°C.

In a recent article published in the magazine for industrial design, the new process Triboconditioning® CG for complex geometries is described. ANS achieves unique features of the surface in terms of smoothness as well as chemical and microstructural composition of the utmost material layer. This results is significant reduction of friction and wear and enables an optimization of parts, which are otherwise difficult to treat with Triboconditioning®, e.g. gears, cam lobes or sheet metal stampings.

In einem in der November-Ausgabe 2020 des Magazin für den Konstruktionsingenieur veröffentlichten Artikel wird das neue Verfahren Triboconditioning® CG für komplexe Geometrien beschrieben. ANS erzielt einzigartige Eigenschaften der Oberfläche in Bezug auf die Rauheit sowie die chemische und mikrostrukturelle Zusammensetzung der äußersten Materialschicht. Dies führt zu einer signifikanten Reduzierung von Reibung und Verschleiß und ermöglicht eine Optimierung von Teilen, die sonst nur schwer mittels Triboconditionieren® zu behandeln sind, wie z.B. Zahnräder, Nocken oder Blechstanzteile.

We are pleased to announce that we have started cooperation with CEVT on improving electric vehicle transmissions within the Swedish FFI framework. In this program, ANS will help CEVT to increase efficiency and drive range by applying the new Triboconditioning® CG treatment on gears in order to minimize friction losses as well as maximizing wear resistance. Further, the Triboconditioning® CG treatment also aims at improving the vehicle’s NVH characteristics by reducing annoying noise coming out of the gearbox. The BEV drivers will thus enjoy a nice and silent ride.
