摘　　要：采用纳秒脉冲激光在45钢表面进行加工,制备了三种不同周期的光栅织构和两种不同周期的微坑织构,并对织构化后的45钢表面进行摩擦磨损测试。测试结果表明,油润滑状态下,织构化的45钢表面摩擦系数无明显减小,但耐磨损效果明显改善,周期为400μm的光栅织构和微坑织构的耐磨性最好。Grating textures with three kinds of periods and micro-crate textures with two kinds of periods were fabricated by nanosecond laser micro fabrication technique on 45 steel surface.Then,tribological testing was conducted on the textured45 steel surface.The results show that the friction coefficient of textured 45 steel surface is basic equal with untextured surface.In addition,textured surface has better anti-wear performance,and grating and micro-crate textures with 400 μm period have the best wear resistance.
