摘要： PURPOSE:To form a thermally sprayed film free of residual bubbles and excellent in adhesion by forming a film to be electrically heated on a base material capable of being electrically heated such as metal and cermet by thermal spraying, diffusing the film into the base material and pressure-sintering the film. CONSTITUTION:The thermally sprayed film of the high m.p. metal, corrosion- resistant metal, etc., to be electrically heated is formed on the surface of the base material made of metal or cermet which generates resistance heat when energized. The base material and film are pressed and heated by a spot welder, etc., hence the film is melted and diffused into the residual bubble to improve its true density, and the film and base material are diffusion-joined to improve the adhesion of the film to the base material. The film is not released in working, and a thermally sprayed film material withstanding severe environment is obtained.

摘要： PURPOSE:To make it possible to coat a base metal with a glass lining material by relieving the difference between the coefft. of thermal expansion of the metal and that of the lining material with thermally sprayed layers formed on the metal. CONSTITUTION:A metallic material, cermet or ceramic having a coefft. of thermal expansion between the coefft. of thermal expansion of base steel to be lined with glass and that of a glass lining material is thermally sprayed on the base steel to form several thermally sprayed layers. At this time, the coefft. of thermal expansion of the layers is gradually reduced from the lower layer toward the upper layer by varying the compsn. of the material to be thermally sprayed and the coefft. of thermal expansion of the outermost layer is made close to that of coating glass. The lining of the base steel with the glass lining material having a low coefft. of thermal expansion is enabled.
