Abstract Influence of laserglaze on the microstructure and corrosion resistance of a cast nickel-base superalloy has been studied, which contains very high contents of refractory metals(Mo 33 Wt％, W 17 Wt％). After surface treatment by laserglaze the alloy structure changes extraordinarily. This change of microstruc-ture has beneficial influence on some of the alloy Properties. Hardness of the laser melted region is evidentiy increased, and corrosion resistance is also improved.
