摘要：
In order to improve the defects of multi-layer Ni/(TiCP/Ni)/Ni composite coating and only TiB2 layer. TiB2-TiC composite coating is a good way. Because TiB2-TiC composite coating layer has well stability in high temperature conditions, high conductivity and TiB2-TiC composite coating layer has better wetting with the surface of copper electrodes in resistance spot welding of Zn-coated sheet steel. The TiB2-TiC composite coating electrodes were investigated by electronic balance, SEM, and microscope during different coating parameters. The best coating parameters include: coating voltage is 24V, coating capacitance is 3000 mu f, coating time about 2 similar to 3 minutes.
