摘要众所周知的高速氨基磺酸镍浴已用于共沉积铬颗粒，以提供成型所需的高电沉积速率。在导电颗粒存在下的电沉积通常会导致树枝状生长和多孔沉积物。我们的研究表明，Cr 含量主要受悬浮液中颗粒浓度的控制，而不是电流密度的控制。研究了影响孔隙率的因素；目前控制枝晶生长的最佳方法取决于机械方法，例如用海绵覆盖的刮刀旋转阴极。为了阐明其机理，已经进行了一些实验，结果表明，如果使用亚微米颗粒进行共沉积，则电沉积物将获得低孔隙率。
SummaryThe wellknown high speed nickel sulphamate bath has been used to codeposit chromium particles to give high rates of electrodeposition required in forming. Electrodeposition in the presence of conducting particles generally leads to a dendritic-like growth and porous deposits. Our investigations have shown that Cr content is mainly controlled by the concentration of particles in suspension rather than the current density. The factors affecting porosity have been studied; the best method of controlling the dendritic growth at present depends on mechanical methods such as rotating cathodes with sponge covered scrapers. Several experiments have been carried out in order to elucidate the mechanism and the results suggest that low porosity in electrodeposits would be obtained if sub-micron particles were used for codeposition.
