330 表面ひずみ計測によるセラミックス溶射SUS304鋼のヒートサイクル損傷過程の観察(OS1-5 環境・高温および熱疲労)(OS1 高強度材・表面改質材の疲労と破壊)  [in Japanese] 330 Surface Strain Monitoring Approach to Heat Cycle Fatigue of Ceramics-Sprayed Type 304 Stainless Steel  [in Japanese]

Heat cycle test of ceramics-sprayed type 304 stainless steel was carried out. Surface strain was measured using the laser speckle strain/displacement gauge (SSDG) during the heat cycle test. Fatigue processes were discussed with result of both surface strain measurement and microscopic observation in the longitudinal section of the specimen. It was found that heat cycle fatigue life of LPPS-bond-coated specimen was longer than that of APPS-bond-coated specimen.
