摘要
采用等离子束在Q235钢基体上熔覆了铁基合金涂层,分析了熔覆过程中温度场的主要影响因素,在考虑边界条件、热源模型、材料非线性的基础上,建立了等离子束熔覆的温度场有限元模型,得到了熔覆层上温度变化规律.分析结果表明:等离子束熔覆温度场呈椭圆形,最高温度达到1 988℃,与试验结果基本符合.
The Fe-base alloy coating was prepared by plasma arc cladding technology. The main effective factor of temperature field was analyzed and its calculation model in plasma arc cladding was built. In the model the main consideration was given to the thermal boundary conditions and heat source. And the temperature field of plasma cladding process on plate was calculated. The analysis results show that simulation results are in accordance with the experimental results. Temperature near the surface of the weld molten is the highest, and up to about 1988℃.
