【Abstract】 NiCr Cr 3C 2 cermet coating was designed and deposited with subsonic velocity flame spraying, and its high temperature oxidation resistance was evaluated in comparison with 20G boiler tube steel and NiCrTi coating which is used widely at present for protection of boiler tubes. The mechanism of high temperature oxidation of NiCr Cr 3C 2 and NiCrTi coatings was explored by SEM and XRD analyses.更多还原
