摘要：

The Mo-N, Mo-C, Mo-Cr modified layers on Ti-6Al-4V alloy were prepared using a double glow discharge plasma alloying technology. Repeated impact tests were performed to evaluate the fatigue behavior of the plasma modified Ti-6Al-4V alloys. Results show that the three surface modified layers exhibited a different depth distribution in microhardness and different failure mode in repeated impact tests. Among the three modified layers the Mo-N has the best matching of impact fatigue strength with hardness. (C) 2006 Elsevier B.V. All rights reserved.
