摘　　要：对涂有酚醛防锈漆的摩擦型高强螺栓连接摩擦面分别采用香蕉水清洗、喷砂、百叶轮砂纸打磨、砂轮打磨等方法做表面处理,并进行抗滑系数试验测试。结果表明误涂防锈漆会严重降低连接面的抗滑移系数,无论经过何种方法进行摩擦面处理,抗滑移系数都不能达到未涂漆的情况。用香蕉水洗、喷砂和砂轮细磨处理摩擦面具有相对理想的效果,测得处理后的连接的抗滑移系数可达到0.30以上,其中砂轮细磨连接面的抗滑移系数可达0.377。利用测得摩擦系数进行设计校核,如能满足设计要求,可采取相应处理措施对误涂油漆摩擦面进行处理。In this paper, the steel junction surface coated with phenolic antirust paint were processed respectively by means of banana oil cleaning, grit blasting, sandpaper polishing, grinding wheel polishing, and then were experimentally tested to determine their sliding coefficients. The testing results show that the coating antirust paint will seriously reduce the sliding coefficient, and no matter what method is used to process the surface, the resistance to slide can not achieve the unvarnished situation. The banana oil cleaning, the grit blasting, and the grinding wheel polishing finely are the relatively good ways to process the surface coated, and the sliding coefficients .of the surface processed are more than 0.30. The coefficient of that treated by the grinding wheel polishing finely can reach 0. 377. If the design check based on the measured sliding coefficient can meet the requirement of the codes, the appropriate method can be used to process the false paint surface.
