Due to the introduction of cleaner and in particular more fuel-efficient engines, it is becoming increasingly difficult to improve or even maintain engine performance levels. The automotive sector has found solutions for these issues, but these solutions come at the cost of higher temperatures and increased wear and tear in the engines, thereby making it necessary to modify the surface materials used in the engine. In contrast to other surface treatments, which do not guarantee a sufficient lifespan, the diffusion-based surface solutions offered by Chromin Maastricht bv provide effective long-term solutions for such issues. The treatment technologies most often used by the automotive sector are hard inchromizing, stainless steel surface hardening, vanadizing and borizing.
