Trivalent chromium plating bath composition and process

摘要

An aqueous acidic trivalent chromium electroplating solution and process for depositing chromium platings employing a bath containing trivalent chromium, a complexing agent, a reducing agent and a controlled effective amount of an anionic or nonionic surface active agent selected from the class of organic mono- or di- or tri-ester phosphates which contributes to improve operating characteristics and efficiency of the electroplating bath and enhances the uniformity of the chromium deposit.
