Abstract: Mo and Mo-N surface modified layers were prepared on Ti-6Al 4 V alloy using a double glow plasma surface alloying technique. Impact tests were performed to determine the critical impact load that characterizes the fatigue behavior of the plasma modified Ti-6Al-4 V alloy. Impact tests on nitrided Ti 6Al 4 V alloy specimens were also performed for comparison. Results show that all the three surface modifications have enhanced the surface hardness and load-bearing capacity of the modified Ti-6Al-4 V alloy, Cohesive failure mode wits observed on all failed specimens. Amongst the three tested surface modifications. Mo modified Ti 6Al 4 V specimens have the best fatigue strength due to the excellent toughness of their surface modified layers, It seems that surface hardness and toughness of the modified layers should be optimized to ensure a better fatigue strength, (c) 2005 Elsevier Ltd.
