METHOD OF FORMING SELF-FLUXING ALLOY COATING LAYER

摘要

PROBLEM TO BE SOLVED: To provide a method of forming a self-fluxing alloy coating layer from a coated film of a slurry composition containing a self-fluxing alloy powder which enables formation of a strong self-fluxing alloy coating layer excellent in adhesion to the surface of a substrate, although a sintering step is carried out in the atmosphere. ! SOLUTION: A method of forming a self-fluxing alloy coating layer includes an application step of applying a slurry composition containing a self-fluxing alloy powder, a binder resin and a solvent to the surface of a substrate, a drying step of drying the coating film formed on the surface of the substrate and a sintering step of raising the temperature of the dried coating film to a specified sintering temperature in the atmosphere and sintering the self-fluxing alloy powder at the sintering temperature to form a self-fluxing alloy coating layer consisting of a sintered body on the surface of the substrate. In the temperature raising stage of the sintering st
