摘要：

To enhance the staying quality of the surface of the copperplate, the laser hybrid cladding technology can be used to clad Ni-Cr alloy on the surface of the copperplate. By the traditional laser cladding technology, it is hard to directly form good coat on the surface of the copperplate. In the article, the coat is made on the surface of the copperplate by the laser hybrid cladding technology, and the staying quality tests are made for samples by several methods, and the micro-hardness and the staying quality of the coat are far higher than the cooper substrate, and coat has good roughness of surface. And the test result indicates that the method adopting the laser hybrid cladding technology can prepare the alloy coat on the surface of the deep copperplate.
