Whether in F1, Nascar, MotoGP, WRC, DTM, or OSS racing, reliable and efficient performance of racing powertrains is critical to racing success. Such powertrains are designed to extract maximum energy from every ounce of fuel, which requires pushing the materials to the limits. This is where Tribobond™ coatings shine, helping to combat wear, decrease friction losses, enable use of lightweight materials and ensure reliable performance.
Valve train components
The Tribobond™ family of coating offers solutions for many critical components of the valve train. Low-friction diamond-like carbon (DLC) coatings (Tribobond™ 40/41/42/43) provide excellent performance in heavily loaded contacts of finger followers, backet tappets and camshafts. A different class of ceramic coatings for high-temperature applications helps protect valve stems and the sealing surfaces of engine valves.
Crank train components
Whenever possible, modern racing engines use lightweight materials to reach optimal engine dynamics and reduce overall weight. Most of these materials (e.g. titanium and aluminum) are relatively soft and cannot provide the level of wear resistance required for stable performance. This is especially true for some components of the crank train, such as connecting rods, pistons and piston pins. Tribobond™ coatings on such components provide a remarkable improvement in surface hardness and wear resistance, with the added benefit of decreasing friction. In extreme cases, the coatings can also be applied to crankshafts for enhancement of their tribological properties and performace boost.
Chassis and suspension
There are many components on the chassis and suspension that benefit greatly from the use of low-friction, wear-reducing coatings to increase their safe functioning. The Tribobond™ line of component coatings offers a wide range of options for individual situations.
Typical parts include:
- Wheel hubs
- Shock absorber tubes (motorbikes)
