Abstract：According to the effect of electric field on atomic diffusion, combined with the advantages of pulse plasma sintering which rapid temperature rise and high cooling rate can be achieved to realize rapidly aluminizing of nickel base alloy. In this paper, the effect of aluminizing temperature on aluminized process of K403 nickel-based superalloy and the high temperature oxidation resistance and wear properties of the Ni-based superalloy were studied. The results show that the aluminized coating with a thickness of about 109 μm is obtained through aluminized at 900 ℃ for 30 min, which belongs to low temperature and high activity aluminizing. The thickness of aluminized layer at 1 000 ℃ is about 89 μm, which belongs to aluminizing at high temperature and low activity. After 1 000 ℃ oxidation, the mass gain from 2.5 mg/cm2 of untreated nickel-based superalloy decreases to 1.3 mg/cm2 of the aluminized nickel-base superalloy, reduced by 48%. Meanwhile, the friction coefficient decreases by 50% from 1.2 to 0.6. The volume wear rate decreases from 4.08% to 0.392%, reduced by 90.4%.
