【Abstract】 The effects of chromium on oxidation-resisting performance of Ni-base alloy at high temperaturehave been studied by SEM,EMP and X- ray diffractormeter. The result show that oxidizing increase of alloy descended and crystallization of oxid film closed with the increase of the chromium contentration in γ- phase. The oxidation- resisting performance of Ni- base alloy at high temperature will be increased.更多还原
