Establishment of New Hybrid Surface Modification Including DLC Coatings as Final Treatment

本研究旨在建立一种有利于提高机械产品性能和效率的复合表面改性新工艺。该工艺由各种DLC涂层（Me-DLC、多层DLC）和预处理组成。目标材料是钛合金和不锈钢，它们的耐磨性较差，但具有良好的功能。本研究就DLC涂层及预处理对摩擦磨损性能、力学性能和疲劳性能的影响积累了系统的研究结果。

This study was conducted to establish a new process of hybrid surface modification which can contribute for improving performance and efficiency of mechanical products. The process was composed of various DLC coatings(Me-DLC, multi-layered DLC) and pre-treatments. The objective materials were a titanium alloy and stainless steel possessing poor wear resistance but fine functionalities together. This study accumulated systematic results concerning the effects of the DLC coatings and pre-treatments on the friction-wear properties, mechanical properties and fatigue properties.
