Our research group devised a technology to create a coating layer with fine powder by continuously sending hard fine powder mixed with carrier powder between the substrate and the tool and rubbing it under local high surface pressure. This is called friction reforming. In addition, we are also working on the combined use of heat treatment for the purpose of hardening the friction reforming layer, improving the adhesion between the friction reforming layer and the substrate, and improving the corrosion and wear resistance associated with these. This paper introduces efforts to develop friction materials that can be used in marine environments by providing corrosion resistance and low friction / wear resistance to high-strength metals using friction reforming technique and heat treatment in combination.
