综合考虑了激光熔覆热流施加、材料传热两方面的自身特点（在热源施加方面，激光熔覆是小面积、快速、分布不均匀的热流输入形式；在材料传热方面，激光熔覆是多层异质、预置涂层多孔非实质的材料传热方式），建立了合理的激光熔覆数值模型，利用有限元法，通过计算模拟，结果表明：所得激光熔覆温度场模拟结果与实际测量情况吻合良好，从而证明了本文数值模型的正确性，为今后各种参数下激光熔覆的温度场模拟提供了一理论基础。
Considering both the application of laser cladding and the heat transfer of materials, laser cladding is a small, rapid and uneven distribution of heat flux in the application of heat source. In the heat transfer of materials, laser cladding is Multi-layer heterogeneous and pre-coating porous non-physical material heat transfer mode), a reasonable laser cladding numerical model was established, and the finite element method was used to calculate the simulation results. The results show that the simulation results of the obtained laser cladding temperature field and The measured results agree well with each other, which proves the correctness of the numerical model and provides a theoretical basis for the temperature field simulation of laser cladding under various parameters in the future.
