英文摘要Oxidation behavior of a Ni-Co-based superalloy prepared by vacuum induction melting (VIM) plus electron beam smelting layered solidification technology (EBSL) and VIM plus electro slag remelting (ESR) at 1180 degrees C was investigated. The predominant oxides from the outer layer to the inner layer are TiO 2 , Cr 2 O 3 , (Al, Ti) -rich oxide and Al 2 O 3 , respectively. The (Al, Ti) -rich oxide is considered to be Al 2 Ti 4 O 9 , which is formed by TiO 2 and Al 2 O 3 . At high temperature, the external oxides experienced significant spalling, particularly in ESR-alloy, which indicated that the EBSL-alloy is more preferable in terms of oxidation resistance. This can be attributed to the presence of finer grains in EBSL-alloy, which facilitates the diffusion of elements and promotes the rapid formation of oxidation scales on the surface of the alloy. Additionally, the presence of a TiO 2 layer cover on Cr 2 O 3 reduces the degree of spalling of oxides in EBSL-alloy.
