中文摘要：

有 0-1.4  at.% 的 Cu 集中的 TiAlN/Cu nanocomposite 涂层在高速度的钢(HSS ) 上被扔由过滤 cathodic 弧离子 plating 的底层技术。化学作文，微观结构，形态学，粘附力量，机械并且 TiAlN/Cu 涂层的 tribological 性质被描绘并且分析。结果表明涂层结构和性质取决于不仅 Cu 集中，而且免职条件。Cu 的增加显著地减少谷物尺寸并且在 TiAlN/Cu 涂层削弱质地。与增加 Cu 集中，涂层坚硬与 1.4  at.% Cu 从纯 TiAlN 涂层的 30.7  GPa 稍微减少到 TiAlN/Cu 涂层的 28.5  GPa。所有 TiAlN/Cu 涂层介绍足够的粘附力量。另外，在 TiAlN/Cu 涂层的添加剂 Cu 的存在状态也被调查。

英文摘要：

TiAIN]Cu nanocomposite coatings with Cu concentration of 0-1.4 at.% were deposited on the high- speed steel （HSS） substrates by filtered cathodic arc ion plating technique. The chemical composition, microstructure, morphology, adhesion strength, mechanical and tribological properties of the TiAIN/Cu coatings were characterized and analyzed. The results reveal that the coating structure and properties depend on not only the Cu concentration, hut also the deposition condition. The addition of Cu significantly decreases the grain size and weakens the texture in the TiAlN/Cu coatings. With increasing the Cu concentration, the coating hardness decreases slightly from 30.7 GPa of the pure TiAlN coating to 28.5 GPa of the TiAlN/Cu coating with 1.4 at,% Cu. All the TiAlN/Cu coatings present sufficient adhesion strength. In addition, the existing state of additive Cu in the TiAlN/Cu coatings is also investigated.
