Method for Manufacturing Cast Iron Member, Cast Iron Member and Vehicular Engine |
摘要 |
There is provided a method for manufacturing a cast iron member in which the production of gas defects such as blowholes or pinholes in a clad layer formed on the surface of a cast iron material can be reduced, and the generation of bead cracks in the clad layer can be restrained. In the method for manufacturing a cast iron member, including a step of forming the clad layer by melting a material for cladding by means of irradiation of a laser emitted from a laser irradiation device and by depositing the melted material on the surface of a part of the cast iron material, the step of forming the clad layer is performed by using a material the main ingredient of which is a copper element as the material for cladding so that when the clad layer is formed, a hardened layer having a thickness of 0.01 to 2.0 mm is formed on the surface of the cast iron material.
