摘要

为了开发能直接应用于海洋环境的自润滑材料,在不锈钢表面制备无氢四面体非晶碳(ta-DLC)膜,分别测试和比较ta-DLC膜在海水、水和油中的摩擦学性能。结果表明:ta-DLC膜在海水中的摩擦系数小于0.1,磨痕最窄且浅,表现出最优异的摩擦学性能,其水中摩擦学性能略差于其海水中摩擦学性能,在油中摩擦学性能最差。ta-DLC膜在海水润滑领域具有广阔应用前景。
        A nonhydrogenated tetrahedral amorphous carbon(ta-DLC) coating was fabricated on the surfaces of stainless steel to develop self-lubricating materials that can be employed directly in the marine environment. The tribological performances of the ta-DLC coating in seawater, water, and oil were tested and compared. Experimental results showed that the ta-DLC coating had a friction coefficient of less than 0.1 and the shallowest and narrowest wear track in seawater. The tribological performance of the ta-DLC coating in seawater was the best and that in oil was the worst. The tribological performance of the ta-DLC coating in water was slightly worse than that in seawater. The ta-DLC coating has extensive potential applications in seawater lubrication.
