摘要

采用湿喷丸技术对Ti-6Al-4V 合金进行表面强化处理，研究了部分滑移、混合滑移和完全滑移等不同状态下钛合金样品的微动磨损行为，从微动状态角度探讨喷丸强化对钛合金微动磨损行为的影响规律。试验结果显示，喷丸处理对于完全滑移状态下Ti-6Al-4V 合金的微动磨损行为影响较小；而在混合滑移状态时，喷丸处理使得微动磨痕的塑性变形积累区消失，有效抑制局部疲劳损伤造成的微裂纹萌生。这是因为喷丸引入加工硬化作用使材料表层局部强度提高，进而改善局部疲劳损伤。

Abstract

Wet peening was taken on Ti-6Al-4V titanium alloy as a surface strengthening treatment. Effect of shot peening on fretting wear behavior was investigated under different conditions of partial slip

mixed slip and gross slip. The fretting wear experiment indicates that wet peening has little influence on fretting wear behavior of Ti-6Al-4V titanium alloy at condition of gross slip. However

wet peening can inhibit crack initiation occurred in accumulation of plastic deformation zone when the condition is partial slip. It is suggested that the improvement of local yield strength at surface layer by shot peening was the key reason for avoiding local fatigue damage.
