| 摘 要： | 以Cr作为中间过渡层,采用磁控溅射的方法在ZL114合金表面制备了类金刚石(DLC)硬质涂层,对比分析了母材与涂层的硬度、耐蚀性能和干/湿摩擦学性能。结果表明:在ZL114合金表面制备了Cr过渡层厚度约为2μm、表面DLC涂层约为10μm的Cr-DLC涂层;Cr-DLC涂层具有DLC薄膜的特性,显微硬度和纳米硬度分别为母材的3.73倍和3.96倍;Cr-DLC涂层的腐蚀倾向和腐蚀速率都要小于ZL114合金母材,ZL114合金表面沉积Cr-DLC涂层后耐腐蚀性能得到提高;母材和Cr-DLC涂层在湿摩擦条件下的摩擦系数和磨损率低于干摩擦条件下,且干/湿摩擦条件下Cr-DLC涂层的磨损率都要低于ZL114合金母材;Cr-DLC涂层在湿摩擦(3.5%NaCl溶液)条件下仍然具有较好的耐磨性。
