High Cycle Fatigue Study of Plasma and Cold Sprayed Ti Layers on Ti6Al4V Substrates
Original language description
The influence of thermal spray technologies on the high-cycle fatigue properties of specimens was studied. Ti powder was deposited onto grit blasted Ti6Al4V substrates using plasma and cold spray technologies. Non-treated specimens (reference set), gritblasted and coated specimens were subjected to fatigue cantilever-beam cyclical bend loading with a constant deflection of the free end. 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 reference set (fatigue life of 462 949 cycles), the grit blasting procedure increased the fatigue life by 81%. Plasma spray deposition of Ti layers induced a drop in the average fatigue life to 65% ofthe grit-blasted set lives and the cold sprayed specimens exhibited the lowest average fatigue lives among the samples, 421 772 cycles, representing only 91% of the reference set lives. Delamination of deposited coatings led to a recover
