摘要

Ni-Co duplex coating has been successfully cladded on copper substrate by continuous wave CO_2 laser. The average microhardness of cladded coating was 635 HV_(0.05). which was about 7 times of Cu substrate (92 HV_(0.05)). During sliding wear tests, the volume loss of copper substrate was about 7 times of Ni-Co duplex coating at 60 min. The high microhardness and crack free advantages of Ni-Co duplex coating, were favorable to reduce the plastic deformation and adhesive wear of copper substrate, resulting in the improvement of wear properties.
