Abstract
Disclosed is a process for producing a rubber-based composite material, including the steps of forming, by sputtering, an adhesion film on a substrate to be mated with a rubber for constituting the composite material, laminating a rubber composition on the adhesion film, and vulcanizing the rubber composition, the sputtering is conducted by using a first target and a second target, composed of different metallic components and provided in a chamber, while moving the substrate in sputtering atmospheres formed by applying electric power simultaneously to the first and second targets. Also disclosed is a process for producing a rubber-based composite material, including the steps of forming, by sputtering, an adhesion film on a substrate to be mated with a rubber for constituting the composite material, laminating a rubber composition on the adhesion film, and vulcanizing the rubber composition, wherein the sputtering is conducted by using a plurality of targets, composed of metals or metallic compounds containing different metallic elements and provided in a chamber, while rotating the substrate in sputtering atmospheres formed by applying electric power simultaneously to the targets.
