Salt-deposit hot corrosion behaviors of directionally solidified DZ466 superalloy

Hot corrosion behaviors of DZ466 alloy at 850℃ and 950℃ were investigated by using a NaCl/Na2SO4salt-deposit method. It is found that there are three corrosion layers on the alloy. The outer and the middle layers consist of(Ni,Co) O oxide and(Ni,Co) Cr2O4 with a spinel structure,respectively. The in...
