Title:
METHOD FOR COATING OF SPRAYED BASE FILM ON COPPER BASE METAL MATRIX
Document Type and Number:
Japanese Patent JPS5983756
Kind Code:
A
Abstract:
PURPOSE: To form flame sprayed copper base film effective as protective coat, by a method wherein the surface of copper base metal matrix is coarsened and the film is formed on its surface by flame spraying and treated by heating it within a specified range of temperature.
CONSTITUTION: The surface of copper base metal matrix composed of copper alloys containing Ag, Fe, Mn, Pb, etc. is coarsened mechanically on by spraying sand and grit or by flame spraying of Mo, Ni, W, Ni-Al alloy, etc. Then, the copper base film is formed thereon by flame spraying and treated thereafter by heating it at 250W1,100°C. Thus, the coating strength of copper base film to copper base metal matrix is increased.
