The poor adhesion of carbon thin films was the main restriction for its massive application in recent years. Physicochemical interaction improvement at the adhesion interface between substrate and thin film is one of the most important fields of rese

In dry sliding, the coefficient of friction depends on the material pair and contact conditions. If the material and operating conditions remain unchanged, the coefficient of friction is constant. Obviously, we can tune friction by surface treatments

Computer simulations are becoming increasingly useful for studying friction, enabling the application of controlled conditions and setups that are not usually achievable in physical experiments and ensuring that no other undesirable variable is actin

Hydrogenated amorphous carbon (a-C:H) thin films show low adhesion on ferrous alloys. The addition of a silicon-containing interlayer could minimize the problem but traditionally high deposition temperatures are still needed (at least 300 °C). Howev

Hydrogenated amorphous carbon thin films (a-C:H) have attracted much attention because of their surprising properties, including ultralow friction coefficients in specific conditions. Adhesion of a-C:H films on ferrous alloys is poor due to chemical
