At present, research on the influence of friction heat on the wear resistance of laser cladding layers is still lacking, and there is even less research on the temperature of laser cladding layers under different loads by a finite element program generator (FEPG). After a symmetrical laser cladding path, the wear performance of the moving jaw will change. The study of the temperature change of the moving jaw material in friction provides a theoretical basis for the surface modification of the moving jaw. The model of the column ring is built in a finite element program generator (FEPG). When the inner part of the column is WDB620 (material inside the cylinder) and the outer part is ceramic powder (moving jaw surface material), the relationship between the temperature and time of the contact surface is analyzed under the load between 100 and 600 N. At the same time, the stable temperature, wear amount, effective hardening layer thickness, strain thickness, and iron oxide content corresponding to different loads in a finite element program generator (FEPG) were analyzed. The results showed that when the load is 300 N, the temperature error between the finite element program generator (FEPG) and the movable jaw material is the largest, and the relative error is 4.3%. When the load increases, the stable temperature of the moving jaw plate increases after the symmetrical laser cladding path, and the wear amount first decreases and then increases. The minimum wear amount appears at a load of 400 N and a temperature of 340 °C; the strain thickness of the sample material increases gradually, and the effective hardening layer thickness increases. However, when the load reaches 400 N, the thickness of the effective hardening layer changes little; the content of Fe decreases gradually, and the content of FeO and Fe2O3 increases. The increase of the moving jaw increases in turn the temperature of the laser cladding layer of the test jaw material, which intensifies the oxidation reaction of the ceramic powder of the laser cladding layer.

对称激光熔覆路径后颚式破碎机动颚板磨损性能的有限元研究

目前，关于摩擦热对激光熔覆层耐磨性影响的研究尚缺乏，利用有限元程序生成器（FEPG）对不同载荷下激光熔覆层温度的研究更是少之又少。经过对称的激光熔覆路径后，动颚的磨损性能会发生变化。动颚材料在摩擦中温度变化的研究为动颚表面改性提供了理论依据。柱环模型建立在有限元程序生成器（FEPG）中。当立柱内部为WDB620（筒内材料），外部为陶瓷粉末（动颚面材料）时，分析100~600 N载荷下接触面温度与时间的关系. 同时，在有限元程序生成器（FEPG）中分析了不同载荷对应的稳定温度、磨损量、有效硬化层厚度、应变厚度和氧化铁含量。结果表明，当载荷为300 N时，有限元程序生成器（FEPG）与动颚材料之间的温度误差最大，相对误差为4.3%。当载荷增大时，动颚板经过对称激光熔覆路径后稳定温度升高，磨损量先减小后增大。最小磨损量出现在 400 N 载荷和 340°C 温度下；试样材料的应变厚度逐渐增加，有效硬化层厚度增加。然而，当载荷达到 400 N 时，有效硬化层厚度变化不大；Fe含量逐渐减少，FeO和Fe2O3含量增加。动钳口的增加反过来又提高了被测钳口材料的激光熔覆层的温度，加剧了激光熔覆层陶瓷粉末的氧化反应。
