英文摘要	Three kinds of hardness counter-bodies(HV680GCr15, HV1500Si3N4 and HV2300Al2O3) were selected as variables to study the evolution of tribological characteristics of TC4 titanium alloy in fretting partial slip regime at room and elevated temperatures. The test results showed that under the three pairs, fretting wear of TC4 alloy were in the typical partial slip region at room and elevated temperature, and no transition to other two regions occurred. The tribological characteristics in partial slip regime were affected by the hardness of counter-bodies significantly: the effect on the degradation of worn surface was the most critical, the morphologies of worn scars were varied from a clearly distinguishable adhesive and slightly slippery zone to a circular intersection with severe plastic deformation generated newly; the profiles were transformed from a concave-convex peak curve to a regular "U"-shape with a sharp center and rough edges. The influence on damage mechanisms was minor, gradually transitions from adhesive to oxidation and adhesive wear. The effect on coefficient of friction was almost negligible, the curve evolved regularly, and the stability values was basically the same. © 2021, Materials Review Magazine. All right reserved.
