ELECTROLYTIC SOLUTION FOR ELECTROCHEMICAL DEPOSIT OF PALLADIUM OR ITS ALLOYS |
摘要 |
The invention concerns an aqueous electrolytic solution with acid pH for electrochemical deposit of palladium or its alloys comprising a palladium compound, and optionally at least a secondary metal compound to be co-deposited in the form of an alloy with the palladium, and comprising further ethylenediamine as complexing agent for the palladium and an organic brightening agent wherein said brightening agent is 3-(3-pyridyl)acrylic acid, 3-(3-quinolyl)acrylic acid or one of their salts. The invention also concerns a method for electroplating palladium or a palladium alloy comprising electrolysis of an electrolytic solution as defined above, using current densities ranging between 0.5 and 150 A/dm<2>.
