Effects of Fretting Parameters on the Fretting Friction-Wear Behaviors of 2Cr13 Stainless Steel

The effects of fretting slip amplitude, load and number of cycle on the fretting friction and wear behaviors of laser transformation hardened, laser melt-solidification cemented and annealed 2Cr13 stainless steel were investigated in this paper. The rasults shown that fretting wear volumes increase with the increasing of the above mentioned three parameters, the changes of the fretting friction coefficient is complicated: along with the increase of load it decreases rapidly at the first, and then this decrease becomes more and more slowly and tends to stabilizing, the enlargement of fretting amplitude has no effect on the fretting friction coefficient.
