Abstract
Running-in periods and friction coefficients of SiC and Si3N4 sliding against themselves under water lubrication were investigated with a pin-on-disk apparatus at sliding speed of 120 mm/s and a normal load of 5 N under ambient conditions. It was found that the running-in period of self-mated Si3N4 is much shorter than that of self-mated SiC, and also that the steady-state friction coefficient of self-mated Si3N4 was lower (≤0.0035) than that of self-mated SiC (0.01). The difference in mechanism was analyzed from the point of view of electronic structure and surface chemistry.
