Alloying method using a laser beam on the surface of a metal or alloy material coated with a plating and repair method on the surface of a damaged material

摘要

The present invention relates to a method for manufacturing a metal or alloy material on a surface of a metal or an alloy material which is formed by plating a metal of an element to be alloyed on a surface of a metal or an alloy material and then melting the surface thereof with a laser beam in air to form an alloy surface of a composition different from that of the base material To an alloying method.;In addition, the method of alloying the surface of the metal or alloy material of the present invention includes a method of surface modification of a metal or alloy material surface.;The method of alloying the surface of the metal or alloy material of the present invention also includes a repair method of the surface of the damaged metal or alloy material.;According to the alloying method using the laser beam of the present invention, an alloy layer excellent in corrosion resistance, abrasion resistance, fatigue resistance and erosion resistance can be formed on the surface of metal or alloy, especially Ni-based alloy.
