【摘要】 设计12组电镀工艺参数,并对304不锈钢进行处理。利用DCAT-21型表面/界面张力仪测量处理前后304不锈钢试样的接触角,根据公式γ(1+cosθ)=2(γsdγd)1/2+2(γspγp)1/2计算处理前后试样的界面张力系数,并利用扫描电镜(SEM)对试样进行形貌分析。结果表明:电镀工艺可以显著的改变304不锈钢试样的界面张力系数,其最大减少量为39.24,最小减少量为0.19。不同的电镀工艺对试样表面形貌的影响不同。同时,获得了12组电镀工艺参数的最佳值。这将为304不锈钢表面颗粒的去除提供科学依据。更多还原

【Abstract】 The 304 stainless steel was treated by twelve different plating processes. Contact angles of 304 stainless steel specimens before and after plating processes were measured by DCAT-21 surface/interfacial tension meter. According to the formula γ(1+cosθ)=2(γsdγd)1/2+2(γspγp)1/2 calculated the interfacial tension coefficients of these samples. The morphology of 304 stainless steel samples before and after plating processes was analyzed by scanning electron microscopy(SEM). The results show that plating processes can significantly change interfacial tension coefficients of 304 stainless steel, the greatest change is 39.24 and the minimum is 0.19. Different plating processes have different influence on surface topography of 304 stainless steel. The best values of the twelve different plating process parameters are achieved. It will provide scientific basis for the removal of particles on 304 stainless steel.更多还原
