  • The fretting wear behavior tests on cylinder contacts of TA16/0Cr18Ni9 have been carried out under the normal load(50N and 80N),frequency(2 Hz) and displacement amplitude(from 80μm to 200μm) using the hydraulic fretting test machine with a high precision.Experimental results showed that the normal loads and displacement amplitudes may have remarkable influence on the damage degree and injury mechanism of materials.Degree of injury of material increases with the increasing displacement amplitude and normal loads,however,the friction coefficients decrease.Three-body layer consists of two parts: plastic deformation layer and debris layer that has effect on the restriction and control in the fretting wear.The analysis found that there are some micro-crack and delamination in the plastic deformation layer,and the abrasive dust have based mainly on the oxide of titanium and titanium alloys,and attached on the surface of wear.Adhesive wear,abrasive wear and friction oxidation are the main fretting wear mechanism.
