Abstract
A basic study on the development of sliding materials which can be used in seawater is made in this paper. As well known, stainless steel and titanium alloy are both fine anti-corrosive materials in seawater, but these are easily worn as resulting from corrosive type of wear in seawater. In order to overcome the disadvantage silicon (Si) particles were embedded into the surface layers of them, by applying the rubbing treatment process which was developed by the authors. The wear tests were done in artificial seawater by using the reciprocating wear apparatus. The results show that the coefficient of frictions are not so improved, but wear resistant properties are improved, especially for Si treated stainless steel mated by the same substrate material. Based on the results the wear mechanism of the developed materials is discussed.
