Coating technology plays a vital role in ensuring the durability and performance of motorsport components, be they cast, machined, 3D printed or electronic. The technology helps to protect them from the harsh environments to which they are subjected and improves their durability and lifespan, reducing the need for frequent maintenance and replacement and aiding motorsport’s drive for sustainability.
Moreover, coatings can enhance the performance of components by reducing friction and improving heat dissipation, helping to maintain an optimal operating temperature and consistent performance. Friction reduction, in particular, is critical in motorsport as it reduces the stress and energy lost in the form of heat, improving overall efficiency in a system.
In this article, we’ll explore various coating technologies currently used in motorsport applications and how they are used to enhance racecar performance.
Material properties
Most coatings are used within the powertrain components at the heart of a racecar. Here they play a vital role in protecting and enhancing performance. The materials used depend on the specific application, but at the very least should have high temperature resistance, corrosion resistance and a low coefficient of friction.
One of the most commonly used coatings for engine components is a thermal barrier coating (TBC). TBCs are applied to internal parts to reduce heat transfer from the combustion chamber to the cylinder head, engine block and other systems to reduce the risk of overheating. For example, a thermal barrier coating on the piston crown and/ or combustion chamber and exhaust ports will
