摘要：
The related factors to affect WC ceramic-metal composite coatings prepared by laser induction hybrid rapid cladding (LIHRC) are investigated. The results show that, with the preheated temperature of substrate increasing, the efficiency of LIHRC increases. The substrate types also have a significant effect on the efficiency of LIHRC, which is determined by the thermophysical properties (i.e. melting point, resistivity and permeability). With the laser specific energy and the preheated temperature of substrate increasing, the dilution of the composite coating increases, while the dilution decreases with the increase in the powder density per area. Moreover, the efficiency of the composite powder not only depends on the laser processing parameters and the preheated temperature of substrate, but also relates to the weight percent of WC particle and the types of the bonding metal during LIHRC.
