Chemical vapor deposition (CVD) of pyrolytic chromium carbide coatings (PCCCs) is proving to be a viable alternative to hard chrome plating used on cylinder piston group components. This article discusses the development and optimization of a CVD process for depositing PCCCs on piston rings and cylinder sleeves. It evaluates the coatings based on friction, wear, and adhesion properties in comparison with coatings produced by other methods.
