© 2014 Brazilian Metallurgical, Materials and Mining Association.This work presents a study on the effect of sliding distance on abrasive wear modes transition in micro-abrasive wear. Ball-cratering wear tests were conducted with specimens of P20 cemented carbide (WC-Co) and M2 tool steel, balls of 52100 steel and abrasive slurry prepared with SiC particles and distilled water. Results were analyzed in terms of Ag (area with grooving abrasion) and Ar (area with rolling abrasion) as a function of sliding distance and pressure; they have indicated that with the increasing of sliding distance and, a consequent decreasing of pressure, there is the transition from grooving abrasion to rolling abrasion.
