摘要

Co-Si modified aluminide coating on nickel based superalloys was prepared by pack cementation process, then microstructure and hot corrosion resistance were studied. The mass gain of Co-Si modified aluminide coating is 0.32mg/cm² after hot corrosion at 1173K for 100h. Si can boost the hot corrosion resistance by improving the formation of Al₂O₃ SiO₂ has low solubility over a wide range of salt acidity and good stability in the melting Na₂SO₄+NaCl, preventing rapid corrosion attack and prohibiting the high fluxing rate.
