Apparatus for improving surface quality of rotary machine parts |
摘要 |
An apparatus for improving the surface quality of a rotary machine part in which a high density beam such as laser beam or electron beam is condensed with collimation to a parallelepiped spatial intensity distribution, the intensity being controllable. The beam is directed to a predetermined surface area of the rotary machine part rotating at a constant angular velocity. A solidified layer formed by rapid solidification of a surface portion of the rotary machine part, which is melted by irradiation by the condensed beam, and a transformation-hardened layer formed below the solidified layer are uniform in thickness, and the transformation-hardened layer is uniformly formed throughout the periphery of the rotary machine part, and thus no cracking and/or pitting occurs.
