On Technology Progress of Plasma vs. Cold Spray: High-cycle Fatigue Study

Popis výsledku v původním jazyce

This paper presents a summary of the research on the influence of the thermal spray technology on the high-cycle fatigue properties of specimens. Bio-grade Ti powder (ASTM F1580, 10-44um) was deposited onto designed-shape Ti6Al4V substrates using plasmaspray and cold spray technologies. SEM and EDX analyses of the micro-structure allowed ascertaining the differences in the physical and chemical features of the deposited layers. Non-treated, grit blasted and the coated specimens were then subjected to cantilever-beam cyclical bend loading with a constant deflection of the free end and the crack propagation in the critical area was monitored via a drop in the natural resonance frequency of the tested bodies. The number of cycles at 40% sample cross-section damage (?fatigue life?) was used as a decisive criterion. It was found that the grit blasting procedure significantly altered the resistance of the Ti6Al4V material to a micro-crack initiation and propagation: as compared to the refer
