Abstract

The research conducted for the characterization of the friction and wear behavior of an austenitic stainless steel is shown. Tests were performed on a ball-on-ring tribometer with an experimental design based on a Taguchi array. The evaluated material was AISI 304 stainless steel and AISI 52100 steel was used as a counterpart. The parameters (and their levels) selected in order to study the tribological response were: slip velocity (0.9 m/s and 2 m/s), normal load (9 N, 19 N and 29 N) and sliding distance (500 m, 1000 m and 2000 m). For the studied conditions, the coefficient of friction resulted in average values between 0.3227 and 0.9674, where the normal load was the most influential parameter. The average values of the coefficient of wear were obtained in the range from 0.000860 to 0.003191. The factor that most affects the coefficient of wear is the slip distance. The wear regime was identified as moderate to severe. The wear mechanism for AISI 304 under the studied conditions was adhesion.
