Introduction Silicon carbide-based materials usually have high hardness (2500 – 2800 HV) and thus have superior wear resistance. Nevertheless, the tribological performance of SiC is determined by many factors, such as the grain size of mated materials or the reactions in the presence of oxygen and humidity in the surrounding atmosphere.
