FORMATION OF METAL-SINTERED LAYER ONTO SURFACE OF METALLIC BASE MATERIAL

摘要

PURPOSE:To prevent the exfoliation of a tape-shaped metallic powder molding and to form a metal-sintered layer having a smooth surface by winding and fixing the metallic powder molding onto the surface of a metallic member by superposing partly the molding via an adhesive fixing material. CONSTITUTION:A tapered face 11a is formed to one surface side at one end 1a of the tape-shaped metallic powder molding. a length of the adhesive fixing material 2 is provided to the other end 1b and a tapered face 12b is formed onto the other surface side thereof. Such metallic powder molding 1 is wound and fixed onto the surface of the metallic base material 3 in a manner as to have overlap parts 10 by bringing the one surface 11 side of the molding to the inside. The member is then sintered in a non-oxidative atmosphere The material 2 induces the condensation polymn. reaction by thermal decomposition during sintering and is converted to a carbon precursor. Said precursor exhibits the function to assist the adhesive fixing of the molding 1 onto the material 3 surface in the temp. range up to about 700 deg.C at which the molding 1 begins to sinter.
