Abstract

PURPOSE: To form a porous layer having high heat transfer perfomance on a metallic surface by mixing a binder with metallic powder and brazing filler metal powder of specific grain sizes to prepare a slurry, and coating the slurry on the metallic surface then heating the same in a non-oxidative atmosphere thereby brazing and joining the same.
CONSTITUTION: A binder is mixed with metallic powder of 20W500μm diameters and brazing filler metal powder of 20W200μm diameters. The binder is preferably a plastic. Suitable liquid is mixed with this mixture to prepare a slurry having uniform and moderate viscosities. The weight ratio of the brazing filler metal powder and the metallic powder is preferably about 1:8. The slurry of the mixture is coated on a metallic surface. Depending upon the thicknesses of the object to be coated, the thickness of the porous layer is controlled. Thence, the coated object is heated in a vacuum, non-oxidative or reducing atmosphere, whereby it is brazed and joined, and the porous layer is formed inexpensively and easily on the metallic surface.
