Effect of surface texturing on friction reduction between ceramic and steel materials under lubricated sliding contact
TL;DR: In this article, the effect of micro-dimples on the frictional properties of a silicon nitride ceramic mated with hardened steel was investigated and it was found that the porosity depended greatly on the size and density of the microdimples, whilst the dimple shape did not significantly affect the friction coefficient regardless of rounded or angular profiles.
