| 摘要 |
The invention relates to an aqueous electrolysis bath of acidic pH for the electrochemical deposition of palladium or its alloys, said bath comprising a palladium compound and optionally at least one compound of a secondary metal to be codeposited in the form of an alloy with the palladium, and also comprising ethylenediamine as a palladium complexing agent, and an organic brightening agent, in which bath said brightening agent is 3-(3-pyridyl)acrylic acid, 3-(3-quinolyl)acrylic acid or one of their salts. It further relates to a process for the electroplating of palladium or a palladium alloy which comprises operating an electrolysis bath as defined above by using current densities of between 0.5 and 150 A/dm<2>. |
