| Outline of Final Research Achievements |
This study was conducted to comprehensively accumulate scientific knowledge concerning the effect of the advanced hybrid treatment composed of plasma nitriding, short-time heat treatment and fine-particle bombarding on additive-manufactured titanium alloy. The results showed that the hybrid treatment improved the fatigue strength of the additive-manufactured titanium alloy to the same level of its wrought material. At the same time, the wear resistance was greatly improved. Moreover, it was shown that the short-time heat treatment was markedly effective to improve the fatigue strength of the additive-manufactured titanium alloy as well as its ductility.
