Abstract
The present invention provides a method for producing a steam turbine member that is highly superior in smoothness. The present invention provides a method for producing a steam turbine member including a cladding layer forming step of forming a cladding layer from a powdered material containing a metal in a region of a base material in which corrosion easily occurs, and a surface heating step of heat-melting a surface of the cladding layer.
Claims9
A method for producing a steam turbine member, comprising:
- a cladding layer forming step of forming a cladding layer from a powder material containing a metal in a region of a base material in which corrosion easily occurs;
- and
- a surface heating step of heat-melting a surface of the cladding layer.
A steam turbine member comprising a corrosion resistant region in which a cladding layer is formed on a base material, wherein a portion from a surface of the cladding layer to a depth of 100 to 200 μm is melted.
