PURPOSE: To reduce qualitative irregularity, to enhance working efficiency, to reduce cost and to perform atmospheric pressure thermal spraying by applying a metal material having a low m.p. and rich in ductility to a synthetic resin material by thermal spraying and further applying a desired to the metal layer by thermal spraying.
CONSTITUTION: First, bond coat 8 is applied to a material to be subjected to thermal spraying composed of a synthetic resin 9. In many cases, copper is thermally sprayed but a material composed of silver, alminum or an alloy is also thermally sprayed. Thereafter, a desired material is thermally sprayed. When an electrical material is simply subjected to thermal spraying, for example, a powder of ceramics such as alumina or alumina titanic is used and thermal spraying is carried out under reduced pressure or atmospheric pressure. When abrasion resistance is imparted, for example, the thermal spraying of a tungsten carbide cermet is performed.
