Study of KCl-induced hot corrosion behavior of high velocity oxy-fuel sprayed NiCrAlY and NiCrBSi coatings deposited on 12CrMoV boiler steel at 700

The hot corrosion behavior of two kind of HVOF-sprayed NiCr-based coatings with different oxide-forming elements (such as Al and Si) was investigated and compared in the presence of KCl salt at 700 ℃. The results showed that the hot corrosion resistance of NiCrBSi coating was superior to that of NiC...
