    • An erosion preventive method of securing reliability in production and in use of an erosion susceptible portion of a target member, such as a turbine rotor blade (41), to thereby provide the portion with an erosion preventive function. An erosion preventive section with an upper and lower double layer structure is formed on the erosion susceptible portion of the target member (1), which portion is susceptible to erosion caused by liquid drops and solid particles in its use environment. To form such a structure, a lower layer (low-hardness layer)(2) of an austenite material and an upper layer (hard layer) having higher hardness than the lower layer and made of a hard material such as satellite are applied by laser build-up welding to such a portion of the target member (1). In the laser build-up welding, a laser beam is applied from a laser source (6) to the portion while the austenite material and the hard material are supplied in the form of a rod or powder by welding material supply means (5).
    • 用于确保生产中的可靠性和使用诸如涡轮转子叶片(41)的目标构件的侵蚀敏感部分的侵蚀预防方法,从而为该部分提供防腐蚀功能。 在目标构件(1)的侵蚀敏感部分上形成具有上下双层结构的防腐蚀部分,该部分在其使用环境中容易受到液滴和固体颗粒的侵蚀。 为了形成这种结构,通过激光施加奥氏体材料的下层(低硬度层)(2)和具有比下层更硬的硬质材料例如卫星的上层(硬质层) 对目标构件(1)的这一部分进行堆积焊接。 在激光积聚焊接中,通过焊接材料供给装置(5)将激光源(6)施加到该部分的激光束,同时以棒或粉末的形式供应奥氏体材料和硬质材料。
