    摘要
  • 摘要: 以Zr55Al10Ni5Cu30非晶态合金棒为电极，利用电火花沉积技术在ZL101铝合金表面制备了锆基合金涂层.利用X射线衍射仪（XRD）、扫描电镜（SEM）、显微硬度计和摩擦磨损实验机等对涂层的微观结构、表面形貌、显微硬度和摩擦磨损性能进行了分析测试.结果表明，沉积层表面较致密、均匀，为典型的“溅射状”花样形貌；沉积层主要由非晶、ZrO2和Cu8Zr3等相组成；沉积层的平均显微硬度为1 555 HV 0.01，约为基材的15倍，摩擦系数仅为0.096，呈现出良好的减摩耐磨特性，沉积层的磨损机制主要为疲劳磨损和磨粒磨损.
    Abstract: Using Zr55Al10Ni5Cu30 (at.%) metallic glass alloy rods as electrode, Zr-based alloy coatings were prepared on ZL101 alloy surfaces by electrospark deposition technique. The microstructure and tribology behaviors of the deposited coatings were analyzed by optical microscope (OM), X-ray diffraction (XRD), microhardness tester, and friction and wear tester. The results show that the Zr-based deposition coating is mainly consists of amorphous, Al(Si), ZrO2 and Cu8Zr3 phases. The surface morphologies of the deposition coatings are formed by deposition points superimposed to each other showing typical splash pattern morphology. The average microhardness of Zr-based deposited coating is about 1 555 HV0.01, the coefficient friction is 0.096, which indicates that the coatings have good friction and wear performance. The main abrasion mechanism of the deposited coating is abrasive wear and fatigue wear.
