Abstract: Using a pin-on-dish wear tester friction and wear behavior of W9Gr4V high speed steel with different diameter and distance of concaves treated by laser texturing methods was investigated at 25 ,200 , 350 and 500 respectively. Semi-sphere-shaped concaves have three different diameters of 150,250,350 microns. Two concaves distance at rows is 250 microns. Distance between concaves at ranks has three classes of 150,250,350 microns. Result shows that samples with concaves exhibited lower wear resistance with increasing of temperature when temperature is ranging from ambient to 500 , and its wear increased slowly when temperature was lower than 200 , but its wear increased sharply when temperature was over 200 . Size and distribution of concaves did affect wear and it is found that the larger the concave diameter and space between two ranks, the lower the concaved sample's wear. Concaved samples exhibited lower friction coefficient with increasing of temperature. The results are helpful for investigating bionic texturing of high temperature anti-wear materials.
