| Research Abstract |
We have been conducting three basic studies to develop sliding materials that can be successfully used in seawater. The first is improvement of the wear resistance of diamond-like carbon(DLC)films in seawater: such films are known to exhibit low friction against almost all mated materials. The second study is on the use of surface modification to confer low friction and high wear resistance to corrosion-resistance stainless steel. The third study concerns surface modification of carbon steel, which is often used in industry, in order to increase its corrosion and wear resistance, and its coefficient of friction. From these studies several findings which are useful for improving sliding properties in seawater were obtained.
