Abstract: Ni-15Cr-5Al-5Si (mass fraction/%) alloy was prepared by powder metallurgy method. After pre-oxidation at different temperatures (500,700,900,1 100℃), cyclic oxidation tests were carried out on the alloy at 1 100℃. The effect of pre-oxidation temperature on the high temperature (1 100℃) cyclic oxidation resistance of the alloy was studied and compared with that of Ni-15Cr-5Al alloy without silicon addition. The results show that the high-temperature cyclic oxidation resistance of the Ni-15Cr-5Al-5Si alloy was higher than that of the Ni-15Cr-5Al alloy. Pre-oxidation improved the high-temperature oxidation resistance of the alloy. With increasing pre-oxidation temperature, the high-temperature cyclic oxidation resistance increased, but the increase effect was not obvious.
