Influence of plasma and cold spray deposited Ti Layers on high-cycle fatigue properties of Ti6Al4V substrates

Popis výsledku v původním jazyce

This paper presents a summary of the research on the influence of plasma and cold spray deposition of bio-grade Ti powder on the high-cycle fatigue properties of Ti6Al4V substrates. Four sets of flat specimens (as-received, grit-blasted, plasma and coldsprayed) were prepared and subjected to cantilever?beam cyclic bend loading with a constant deflection of the free end. It was found that the grit-blasting procedure significantly increased the fatigue lives of the specimens compared to the as-received set (1.81 x increase). The deposition of the coatings onto grit-blasted specimens led to deterioration of fatigue properties. The average fatigue lives of the plasma sprayed and cold sprayed samples reached 1.16 x and 0.91 x of the as-received specimens,respectively. In order to understand the positive effect of the grit-blasting procedure and the adverse effect of the coatings deposition on fatigue lives, chemical analyses, fractographic analysis, microstructural investigations as well
