Title
(EN) Surface modifying method and device
(ZH) 表面改质方法及装置、旋转部件及流体机械
Abstract
(EN) A spraying film is formed on the surface of a base material (42), and the spraying film is high-frequency-induction-heated while a portion in the vicinity of the surface layer of the spraying film is kept non-fluidized to thereby re-melt a portion on the lower layer side of the vicinity of the surface layer and allow the spraying film to closely bond to the base material (42). This method can smoothly form a quality, wear-resisting film on the surface of a base material to thereby modify the surface of even a complicated-shape matter to be treated having an inclined portion.
(ZH)

在母材(42)的表面上形成喷镀皮膜,通过一边将该喷镀皮膜的表层附近保持在非流动状态一边对该喷镀皮膜进行高频感应加热,使表层附近的下层侧再熔化,将该喷镀皮膜密合在母材(42)上。根据该方法,即使是具有倾斜部分的形状复杂的被处理物,也能顺利地在母材的表面上形成品质良好的耐磨损性皮膜,能够对表面进行改质。
