中文摘要	Shot-peening and ion implantation were adopted to treat the surface of machined specimens of Ti-6-22-22 alloy, then stress-controlled fatigue tests were performed at room temperature and 400 degreesC. Experimental results indicate that the effects of shot-peening and ion implantation C on the S-N curves are dependent on temperature. For Ti-6-22-22 alloy fatigued at room temperature, the effects of both, shot-peening and ion implantation of carbon ions on fatigue strength at high cyclic lives are slight. At 400 degreesC, the fatigue strength at high cyclic lives is obviously increased for both. shot-peening and ion implantation of carbon ions in comparison with the untreated counterparts.
