英文摘要
Fatigue tests were conducted at both 893K and room temperature for a zirconia-sprayed type 304 stainless steel. Surface strain was monitored by using a laser speckle strain gauge during the fatigue test to examine the fatigue processes such as cracking and, delamination of subsurface layer. Fatigue life of an Atomospheric Plasma Spraying(APS) zirconia-coated specimen was similar to that of a blasted substrate. A cracking occurred in the ceramics layer at the early stage of fatigue failure and the crack penetration into the substrate. In case of a Low Pressure Plasma Spraying (LPPS) zirconia-coated specimen, the fatigue life was longer than that of a blasted substrate. The bond coating layer made by LPPS was found to restrain a crack from initiating in the substrate.
