Abstract

PURPOSE:To join easily and positively two or more materials selected from a group of metals, rubbers and plastics with good adhesion, by forming a flame- sprayed coating layer on at least one of the materials, and joining the materials via this layer. CONSTITUTION:In the production of a composite body by joining two or more materials selected from a group of metals, rubbers and plastics, a flame-sprayed coating layer is formed on at least one of the materials, and the materials are joined via the sprayed coating layer. The formation of the flame-sprayed coating layer is made by a direct method wherein a spraying material is directly flame-sprayed, or an indirect method. In the indirect method, the surface of a mold is sprayed with a spraying material to form a sprayed coating layer, then a metal, rubber, or plastic is joined to the sprayed coating layer directly or via an adhesive, and finally the mold is removed. The indirect method is suitably used for a material which becomes hardly adhesive after the hardening by heating such as a vulcanized rubber. In the case of the indirect method, the material for the mold is selected such that it can be removed easily from the sprayed coating layer.

For example, when joining metal and rubber or plastic, the metal is blasted to improve the adhesion at the bonding interface, but the blasted composite has poor durability on the blasted surface. not enough. Therefore, to avoid this, metals are subjected to chemical conversion treatment, but chemical conversion treatment has the disadvantages of hot treatment, such as increased equipment costs, the need for wastewater treatment, and difficulty in treating large objects.

Furthermore, when joining difficult-to-adhesive plastics such as rubber and thermosetting resins, they are subjected to appropriate treatments such as chromic acid treatment, flame treatment, metallic sodium treatment, plasma treatment, and corona discharge treatment. Even if these methods are used, the adhesion effect is often insufficient, and it is generally difficult to process large articles with these methods.

Furthermore, in the past, packing or gaskets have been inserted between parts where airtightness is required; however, this method of maintaining airtightness by interposing packing or gaskets is There is a problem with long-term security due to component creep. For this reason, in places where such airtightness is required, it is considered preferable to permanently fix seals and gaskets to the component rather than simply inserting them into the component drawing. There have also been few proposals for joining techniques that enable fixation.
