摘　　要：耐热钢S51740被广泛应用于燃气轮机中压气机等热端部件,摩擦磨损是导致其失效的主要原因之一。研究在400℃、600℃和800℃对其进行高温硬度及高温摩擦磨损实验,并基于ANSYS LS-DYNA对磨损过程中的磨损形貌、应力应变及瞬态温度进行数值模拟。结果表明:随温度升高,材料硬度降低,磨损形式由磨粒磨损向黏着磨损转变,磨损量逐渐升高;数值模拟发现,摩擦会导致局部材料的温度升高,加速材料的磨损;该材料在600℃以内具有较高的热强性和耐磨性。本研究为延长材料服役时间,提高零部件经济性具有一定的参考价值。Heat-resistant steel S51740 is widely used in hot-end components such as compressors in gas turbines,and friction and wear are the main reasons for its failure.In this study,high-temperature hardness,high-temperature friction and wear experiments were carried out at 400℃,600℃ and 800℃,respectively.The wear morphology,stress-strain and transient temperature during the wear process were numerically simulated based on ANSYS LS-DYNA.The results show that:with the increase of temperature,the hardness of the material decreases,the wear form changes from abrasive wear to adhesive wear,and the wear amount increases gradually;Numerical simulations show that friction causes local material temperature increase and accelerates the wear of material.The material has high thermal strength and wear resistance within 600℃.This research has a certain reference value for prolonging the service life of materials and improving the economical values of the parts.
