Finite Element Analysis and Experimental Study on Temperature Field of 4Cr5MoSiV Cladding Ni60
4Cr5MoSiVis a widely used material in the mold industry.Laser cladding is an emerging repair process.In order to re-veal the variation of temperature in laser cladding zone is an important basis for guiding the rational selection of cladding param-eters of 4Cr5MoSiVdie steel cladding with Ni60 powder.The finite element technique was used to model and analyze the tempera-ture field of the cladding zone,and the synchronous powder feeding process was simulated.The influence of laser power and scan-ning speed on the temperature field distribution law was studied.The simulation results were confirmed by experiments.The results show that:The depth of the zone and the single point temperature field are proportional to the laser power and inversely proportion-al to the walking speed.For better cladding effect,the laser power in the repair process is preferably greater than 1600W.
