Title:
【発明の名称】プロセス有機物で電解液から金属を電解的に析出する方法
Document Type and Number:
Japanese Patent JP3454829
Kind Code:
B2
Abstract:
The invention concerns a method of electrolytically depositing metals from electrolytes containing organic additives designed to give particular physical properties. Such additives are continuously lost during galvanization, resulting in the formation of decomposition products which spread throughout the whole galvanization plant and are thus deposited on the articles being galvanized. The aim of the invention is therefore to avoid defects in the deposited layers caused by organic residues, thus ensuring continuous deposition of the metal and uniform quality of the metal layers produced. This aim is achieved by physically limiting the organic additives to that part of the electrolyte in which they are relevant. The electrolyte is cycled through a filter in order to keep it free of organic additives. Topping up with organic additives is carried out as a function of additive losses immediately outside that part of the electrolyte in which the additives are relevant.
