Abstract

In order to analyze temperature field of Co-based alloys laser cladding, the model of Co-based alloys laser cladding with preset-powder method has been made by finite element method. The temperature field of coatings was analyzed by SYSWELD software, and Experimental verification is done. The results showed that temperature field changed from non-steady-state to steady-state in the laser cladding process. Favorable metallurgy bonding with 8.26% dilution was obtained by scanning velocity was 5 mm/s, the temperature gradient of surface coatings is obviously decreased to 1/20 of bonding interface, the solidification rate of surface is nearly 70 times of bonding interface. Right power with 1.6 kW and 1.87 kW was found when scanning velocity was 3 mm/s and 4 mm/s by SYSWELD software. Based on solidification theory, shape factor of crystallization are analyzed, these are consistent with experimental results. These results provide reference and guide for parametric optimization and control dilution rate of laser cladding. Key words: Laser cladding, Co-based alloy, SYSWELD, Simulation
