Title:
METHOD FOR PRODUCING FINELY PATTERNED MOLDED PRODUCT BY METAL SPRAYING
Document Type and Number:
WIPO Patent Application WO/2020/218207
Kind Code:
A1
Abstract:
Provided is a method for producing a finely patterned molded product, wherein a molten metal is sprayed onto the surface of a substrate, on which a desired surface morphology can be formed, to form a film, thereby obtaining a thin plate having a desired surface morphology. This method is a method for producing a finely patterned molded product, which is given a surface having a fine concavo-convex structure pattern, through metal spraying using metal powder, the method being characterized in that the metal powder is sprayed together with flames onto a substrate which has a surface having an inverted fine concavo-convex structure pattern with respect to said fine concavo-convex structure pattern, a film having a flat thickness is formed on the surface of the inverted fine concavo-convex structure pattern of the substrate by burying protrusions and recesses of the inverted fine concavo-convex structure pattern by means of a quenching spray gun by which a melt of the metal powder that is made molten due to the heat of the flames is sprayed in the flames and is cooled by a refrigerant for each flame to form a film on the surface of the substrate, and the film is released from the substrate to thereby obtain a molded thin plate which has a surface having a fine concavo-convex structure pattern.
