Fatigue properties of materials with protective thermally deposited layers
Original language description
spray technologies were used: plasma spray, warm spray, low-pressure cold spray and portable cold spray. The specimens were then tested for the influence of the coatings deposition on the fatigue lives. The results were compared to as-received set and grit-blasted set and the causes of the failure were investigated for each set. It was found that the grit-blasting did not alter the fatigue lives of the steel specimens (1% increase as compared to the as-received set), while all thermal spray technologiessignificantly increased the measured fatigue lives. The thermal technologies led to relative lives increase of 210% (portable cold spray), 234% (lowpressure cold spray), 303% (plasma spray) and 355% (warm spray). The increase in relative lives of the individual sets could be attributed to a combination of fatigue resistant coatings and introduction of compressive peening stresses into the substrates.
