摘要： A method is provided, which ensures reliability during manufacture and in the use environment, and allows affording erosion prevention capability in an inexpensive manner, to an erosion-susceptible portion such as turbine rotor blades. An erosion preventive section 4, comprising a lower layer (low-hardness layer) 2 of an austenitic material, and an upper layer (hard layer) 3 of a hard material, such as stellite, harder than the low-hardness layer 2, is formed by laser build-up welding on a portion, which is susceptible to erosion caused by liquid droplets and solid particles in a use environment, of a target member 1 such as a turbine rotor blade. Laser build-up welding is carried out through irradiation of a laser beam from a laser light source 6 while a welding material supply means 5 supplies an austenitic material and a hard material in the form of, for instance, a rod, powder or the like.
