Abstract

Through analyzing and testing the microstructure and chemical component of the samples after laser remelting, the influence of laser remelting on K423A nickel-base superalloy were studied. The results showed that, laser remelting had a significant influence on surface topography of K423A nickel-base superalloy. With the increasing of laser power, the laser molten pool grew in both depth and width. The Similar situations occurred with the increasing of laser frequency. Meanwhile, the influence on chemical component of K432A was not that obvious. The content of major elements changed little, but Al content reduced.
