摘要
基于Ansys软件仿真电子束熔覆过程中的温度场分布规律,估测熔覆层截面熔化深度、熔化宽度值,进而通过仿真估测熔覆层稀释率值的大小,随后进行电子束熔覆实验并计算稀释率的实际值,对比模拟值与实际值的情况,确认通过仿真可得出电子束熔覆的稀释率值。测试熔覆后试样的显微硬度和典型试样的耐磨性能,结果表明稀释率值小的试样,熔覆层的质量更优异。
Based on the distribution law of temperature field in the electron beam cladding process simulated by ANSYS software,the melting depth and melting width of the cross section of cladding layer were investigated,and then the dilution ratio of cladding layer was estimated through simulation.Afterwards,the electron beam cladding experiment was conducted to measure the actual dilution ratio.Through the comparison between simulated and experimental dilution ratios,it can be verified that the dilution ratio of electron beam cladding can be obtained by simulation.The microhardness and the wear resistance of specimen after cladding were investigated.Results show that the smaller the dilution ratio,the better the quality of the cladding layer.
