摘要:
通过高能喷丸方法（HSP）使工业纯钛获得约60 μm的表面纳米层，并通过表面形貌仪对喷丸后表面粗糙度进行了测量，结果表明，纯钛表面HSP处理后，表面粗糙度增大，喷丸10 min时粗糙度达到最大值，继续喷丸粗糙度降低，喷丸60 min时粗糙度趋于稳定。喷丸时间60 min时表面粗糙度对其疲劳性能的影响最小，表面纳米化效果最佳。

Abstract:
Surface nanocrystallization of pure titannium was obtained by means of HSP, and then the variation of Ra was measured by the profilometer. The results showed that Ra increases after surface nanocrystallization, which can cause stress concentration and accelerate the initiation of cracks on the surface, therefore will decrease the fatigue intensity. The effect of shot peening for 60 minutes was best.
Key words:  surface nanocrystallization  pure titannium  surface roughness  stress concentration
