Effect of Laser Energy on Friction and Wear Properties of Laser Shock Peened 45 Steel
-
摘要: 在不同激光能量（4，6，8 J）下对45钢试样表面进行激光冲击强化，研究了激光能量对试样显微硬度、残余应力、微观结构和摩擦磨损性能的影响。结果表明：随着激光能量的增加，45钢的晶格畸变程度、残余压应力、显微硬度和耐磨性能不断提升。在8 J激光能量下，45钢的表面（211）晶面半高宽、残余压应力和显微硬度分别增加到3.50°，500 MPa，345 HV，摩擦因数和磨损质量损失分别减小到0.61和157 mg，同时磨损表面剥落物最少，犁沟的深度和宽度最小。45钢摩擦磨损性能的提升与激光冲击强化诱导的高密度位错结构和高幅值残余压应力有关。Abstract: Laser shock peening was conducted on the surface of 45 steel specimens under different laser energy (4, 6, 8 J). The effects of laser energy on the microhardness, residual stress, microstructure and friction and wear properties of the specimens were studied. The results show that with the increase of laser energy, the degree of lattice distortion, compressive residual stress, microhardness and wear resistance of 45 steel were improved. Under the laser energy of 8 J, the surface (211) crystal plane full width at half maximum, residual compressive stress and microhardness of 45 steel increased to 3.5°, 500 MPa and 345 HV, and the friction coefficient and the wear mass loss decreased to 0.61 and 157 mg, respectively; the wear surface had the least peeling material, and the depth and width of the furrow were the smallest. The improvement of friction and wear properties of 45 steel was mainly due to the high-density dislocation and high-amplitude compressive residual stress induced by laser shock peening.
