摘要：研究了采用硅质量分数为50%的Fe-Si合金颗粒为原料,以循环镀液电沉积法制备Fe-Si复合镀层,考察了电极位向、镀液流速、颗粒质量浓度及电流密度对Fe-Si复合镀层形貌及硅质量分数的影响。结果表明:采用竖直电极电镀时,当电镀槽镀液向下循环搅拌时,获得的镀层中硅质量分数较低;当镀液向上循环时,镀层中硅质量分数随镀液流速增大呈先升高后降低趋势,镀层硅质量分数达10.33%;采用水平电极电镀时,随镀液流速增大,镀层中硅质量分数呈先升高后降低趋势,镀层硅质量分数可达28.47%,但显著高于竖直电极电镀时获得的镀层硅质量分数;同时,随电流密度增大,采用竖直电极电镀获得的镀层硅质量分数升高,在电流密度为2.5A/dm^2时达最大;采用水平电极电镀获得的镀层硅质量分数随电流密度增大而显著降低。
Fe-Si composite coating was prepared using Fe-50%Si alloy particles by electrodeposition of circulating electrolyte. The effects of electrode orientation, liquid flow velocity, particle concentration and current density on the morphology and silicon content of Fe-Si coating were examined. The results show when in vertical electrode system, the silicon content in coating is very low by down cyclic electrolyte,the silicon content in coatings first increase then decrease and reach the maximum of 10.23% by up cyclic electrolyte. In level electrode system, the silicon content in coating first increase then decreased,but much higher than that by vertical electrode plating,the silicon content in coating can be up to 28.47%. At the same time,with increasing of current density,silicon content increase in vertical electrode plating coating and reach the maximum at current density of 2.5 A/dm2 , but further increases the current density, the silicon content in coating decrease. The silicon content in coating significantly decrease with increasing of current density in level electrode plating system.
