The Effect of TIN /Ti Composite Film and Multilayer on Fretting Fatigue Resistance of Ti811 Alloy at Elevated Temperature
TIN / Ti 复合膜与多层膜对Ti811 合金高温摩擦性能及微动疲劳抗力的影响

TiN/Ti composite film was prepared on Ti811 surface by vacuum cathode arc deposition(VCAD) and magnetron sputtering(MS) technique,respectively.TiN/Ti multilayer was deposited by MS.The composition distribution,bonding strength,micro-hardness and ductility of the films were measured.The effects of the films with different structures on the tribological property and fretting fatigue(FF) resistance of the titanium alloy substrate at elevated temperature were comparatively studied.The results indicated that bot...
