Abstract: The laser cladding Cu/Cr alloy layers on commercial pure aluminum AA6061 which exposed to the atmosphere rapidly oxidizes,it is hardly to deal with since their melting points are quite different and the cracks are easily induced in the bound zone of cladding layers.This paper investigated the influences of laser process parameters on cracking trend in the bound zone by means of scanning electron microscope (SEM).The results indicate:the Cu/Cr cladding layers with pores and crack free can be prepared on Al substrates by the focusing Nd:YAG laser beam as a heating source under suitable laser process parameters,which is very useful to improve the surface properties of aluminum and furthermore to spread the applied values of aluminum as the electronic contacts.
