i T S S e the disc wear test. The good candidate [Fig. 3(b)] shows very little noise level indicating excellent low wear characteristics with no galling and a low friction coefficient. Based on this study, Triboglide coating without silver was chosen as the candidate for testing on the Honeywell foil bearing shaft.
