摘要

The friction coefficient and wear rate in structural ceramic materials are often too high to make them attractive for applications requiring dry sliding. The role of a thin soft silver film in improving the tribological characteristics of silicon nitride materials is investigated in this study. In a pin-on-disc contact configuration in reciprocating motion, the friction coefficient was reduced by about 50% and the wear rate by one to two orders of magnitude. The friction reduction is thought to be due to the reduction of the contact interface shear strength by the presence of the soft film. The wear rate reduction is likely due to modification of the contact stresses by the film. Combined, these two factors lead to a decrease in the magnitude of the damaging tensile stresses. The durability and thus the effectiveness of the film is very dependent on the bond strength (i.e., adhesion strength) between the film and the substrate. 21 refs., 4 figs., 1 tab.
