Summary for hard chrome plating peel off Discussion
Hard chrome plating peel off after chemical additions is the issue raised by Behrouz Rezaei of Tehran, who says the bath has been peeling for some time after chromic acid and catalyst are added. In response, the answerer says the post does not provide enough information to diagnose the cause and notes that the assumption that the additions are responsible may be correct, but is unproven. He says he cannot think of a clear explanation from the details given and asks for more data, especially what part is being plated, before anyone can offer useful troubleshooting advice. The main takeaway is that the problem may be related to the bath additions, but the thread does not establish a cause and needs more process information.

A. Hi cousin Behrouz. Your question offers no information except your conclusion that the peel off problem is caused by the addition of chromic acid and catalyst. That conclusion may be right, and a reader may be able to help you, but I can’t think of a good explanation myself 🙂
If you’re open to the possibility that the cause might be otherwise, we would need to hear some data including what it is that you are plating.
Luck & Regards,
