The purpose of this work is to study the influence of the micro-abrasive wear modes on the behaviors of the
\nvolume of wear (V) and on the coefficient of friction (µ) of thin films. Experiments were conducted with thin
\nfilms of TiN, TiAlN, TiN/TiAlN, TiHfC, ZrN and TiZrN, using a ball of AISI 52100 steel and abrasive slurries
\nprepared with black silicon carbide (SiC) particles and glycerine. The results show that the abrasive slurry
\nconcentration affected the abrasive wear modes (“grooving abrasion” or “rolling abrasion”) and, consequently,
\nthe magnitude of the volume of wear and of the coefficient of friction, as described: i) a low value of abrasive
\nslurry concentration…
