摘要: Abstract This study was conducted to comprehensively investigate the effect of combination treatment on wear resistance, mechanical properties, and fatigue strength Ti–6Al–4V alloy. The composed plasma nitriding, short-time duplex heat (hereafter, treatment), fine-particle bombarding (FPB). A hardened layer formed by nitriding. substrate strengthened treatment. brittle compound layer, eliminated FPB, also high compressive residual stress introduced. Wear resistance improved treatment; however, hybrid surface treatment, nitriding more effective improve than tensile 30% Fatigue crack initiation from strongly suppressed introduced stress. Moreover, subsurface substrate. As a result, greatly improved, 59%,
