摘要(Abstract)：

采用等离子和电弧两种方法制备厚度不同的Ni-Cr-Al涂层,对比涂层在不同喷涂工艺下的组织结构、结合强度、涂层挠度和耐磨性能,并研究涂层结合强度和挠度随涂层厚度变化的规律。结果表明:涂层组织均呈现出典型的层状结构特征,界面结合良好。结合强度和挠度均随着厚度的增加而降低,当厚度>0.5 mm时,等离子涂层的结合强度和挠度随厚度下降的幅度要大于电弧喷涂涂层,其中等离子涂层最大厚度为1.3 mm时结合强度为21.57 MPa,挠度为10.9×10-3in(l in=25.4 mm),而电弧喷涂涂层厚度为2.2 mm时的结合强度为22.79 MPa,挠度10.3×10-3in,涂层的绝对磨损量随着磨损时间的增加而升高,但相对磨损量则降低,涂层的磨损量随着磨损试验载荷的增大而增大。
