摘　　要：采用有限元法中的电磁-热耦合技术,建立了感应熔涂温度场模型,研究了感应熔涂温度场的分布、变化规律及影响因素。结果表明,熔涂过程中,电流频率、密度和加热时间都对温度场有明显影响。此外,高频电流下,高温趋于熔覆层,是感应熔涂的一个明显特点。Using electromagnetic-thermal coupling technology in finite element method,the temperature field model of Cylinder Workpiece in induction cladding was established,the temperature distribution,variation and influence factors in induction cladding was studied.The results show that,in the cladding process,the current frequency,density and heating time have obvious influence on temperature field.In addition,under high frequency current,it is an obvious characteristics in induction cladding that high temperature tends to the cladding layer.
