Fretting Behaviour of 1Cr13 Stainless Steel from Room Temperature to 400℃ in Gross Slip Regime and Slip

Fretting wear behaviour of the 1Cr13 stainless steel from room temperature to 400℃ were investigated on a Deltalab-Nene7 fretting wear test rig. Dynamic analysis and microscopic examinations have shown that the fretting behavior depended strongly on the fretting regime. Coefficient of friction and wear volume reduced as the increasing of temperature in slip regime, and little difference was observed in partial slip regime. The fretting wear mechanism is analyzed: As the temperature increases, an oxide film forming on the surface of 1Cr13 stainless steel for the high temperature oxidizing. The crack on oxide film generates and fractures under the effect of fretting, and the crack propagates parallel to the surface. The wear debris is de- tached from the substrate by the repeated stress action.
