We investigated the improvement of the function of stainless steel with coating titanium oxide film. Especially, hydrophilicity of titanium oxide improves heat transmission coefficient of stainless steel and water. This property improves very much thermal efficiency of heat engine of stainless steel. TiO_2 films were coated with RF magnetron Sputtering method on stainless steel. This method has high advantage of adhering force than Sol-Gel method and Dipping method.The relation between the formation condition of film and the contact angle of water droplet was evaluated. It was found that the crystalline structure of titanium oxide affects the contact angle and stability of hydrophilicity. The anatase TiO_2 showed high hydrophilicity than rutile structure. This phenomenon was explained by the function of bridging site oxygen. We found the optimum formation condition to accomplish high photophilicity and adhering force.

研究了涂覆氧化钛膜对不锈钢性能的改善作用。特别是氧化钛的亲水性提高了不锈钢与水的传热系数。这一特性大大提高了不锈钢热机的热效率。采用射频磁控溅射法在不锈钢表面涂覆TiO_2薄膜。与溶胶-凝胶法和浸渍法相比，该方法具有较高的附着力。评价了膜的形成条件与水滴接触角的关系。研究发现，氧化钛的结晶结构影响了接触角和亲水性的稳定性。锐钛矿TiO_2具有比金红石结构更高的亲水性。这种现象可以用桥接位点氧的作用来解释。我们找到了最佳的形成条件，以获得较高的亲水性和粘附力。
