| Outline of Final Research Achievements |
Friction reforming technique is a technical treatment to create a coating layer of hard powder by continuously feeding a mixed of hard fine powder that easily alloys with the base material and carrier powder between a base material and a tool and rubbing them under local high pressure. In this study, this friction reforming technique and heat treatment were used to provide a high strength metals with a surface having high adhesion and corrosion resistance, low friction and excellent wear resistance in seawater. And then, we obtained useful results that contribute to the development of high strength frictional materials that can be used in seawater through various evaluation test.

| Academic Significance and Societal Importance of the Research Achievements |
海水中用高強度摩擦材に必要とされる条件は，耐食性と低摩擦・耐摩耗性を有することが挙げられるが，これらを海洋環境の汚染なく満足する摩擦材は強度・耐久性に難がある高分子材料を除けばほとんどなく，またこの分野の研究自体極めて少ないのが現状である．本研究では，強度の高い金属に，優れた耐食性と低摩擦かつ優れた耐摩耗性を独創的な方法で付与し，海水中にて使用可能な高強度の摩擦材の開発に資する有益な成果を得ることができた．これは学術的にも社会的にも意義のあることである．
