摘　　要：采用激光织构技术在激冷合金铸铁表面制出不同尺寸沟槽形织构,开展摩擦磨损试验,研究织构间距和织构宽度对摩擦系数和磨损量的影响。结果发现,当织构间距和宽度均为100μm时,试样与对磨球间平均摩擦系数值为0.1885,试样磨损量为17.1mg,与无织构时相比显著降低。研究表明沟槽形微织构可有效提升激冷合金铸铁表面的耐磨性。�Laser texturing technology was employed to create groove-shaped micro-textures of varying dimensions on the surface of chilled alloy cast iron.Friction and wear tests were conducted to investigate the effects of micro-texture spacing and width on the friction coefficient and wear loss.It was found that when the spacing and width of the micro-textures were both 100μm,the average friction coefficient between the specimen and the counter-face ball was 0.1885,and the wear loss of the specimen was 17.1mg,which was significantly reduced compared to the non-textured condition.The study indicates that groove-shaped micro-texture can effectively enhance the wear resistance of the surface of chilled alloy cast iron.
