Summary

Tribological behavior of plasma-treated silicon nitrides was investigated. The coefficient of friction was measured with a tri-pin-on-plate machine lubricated with a small amount of commercial engine oil. Some of the tests on plasma-treated silicon nitride specimens resulted in a coefficient of friction as low as 0.01, while other tests showed normal values around 0.12. A high bias voltage and a relatively low substrate temperature were thought to be responsible for the ultra-low friction behavior. The surface was analyzed by scanning probe microscopy in order to clarify the friction mechanisms involved.
