摘　　要：运用改装的摩擦试验机对45钢——灰铸铁HT150摩擦副做旋转对磨试验。在摩擦副中加入有机硅酸盐试剂, 在变载荷、定转速条件下在大气环境中进行试验。主要探索有机硅酸盐材料对45钢摩擦副表面改性的机理和耐磨规律。试验发现45钢摩擦试样表面有一层光滑、平坦的乳白色膜生成,微观发现有的区域有大量小质点镶嵌,表面微区亦增添了来自有机硅酸盐中的元素,显微硬度明显提高,表面粗糙度显著降低。起到了良好的减摩耐磨效果。The effects of organic silicate on the fiication performance of 45 steel/HT150 pair are studied by an improved frication apparatus. The reagent of organic silicate is added to the pair, and then the fiication experiment is carried out under variable load, constant velocity and air conditions. The results show that there is ivory-white film on the surface of 45 steel. Investigation by microscope indicates that many particles, such as the elements of organic silicate are embedded into the surface. The micro-penetration hardness and surface roughness are greatly increased and decreased respectively, which demonstrate the pronounced abrasion-resistant effects of organic silicate.
