In order to extend a life of sliding surfaces, we developed an aged surface by mirror finishing and aging surface with 10 um features and 10 um lubrication film.Through sliding life tests, it has confirmed that the mirror finished surface had ten times longer life compared with the conventional one. The surface with 10 um lubrication film worked only for 1 minute, because the film peeled off. To solve this problem, we strengthen the film by putting fillers in the film. A composite plating with particles with several micrometers in diameter produced a 10 um feature on the lubrication film, and it achieved higher hardness than normal lubrication film.

为了延长滑动表面的使用寿命，我们开发了镜面老化表面，老化表面具有10um特征和10um润滑膜。通过滑动寿命测试，证实镜面抛光表面比传统表面寿命延长了十倍。具有10um润滑膜的表面仅工作1分钟，因为膜脱落。为了解决这个问题，我们通过在薄膜中添加填料来增强薄膜。直径为数微米的颗粒的复合镀层在润滑膜上产生了10微米的特征，并且获得了比普通润滑膜更高的硬度。
