CrN stripping by chemicals
I want to use chemicals to strip the CrN coating on the stainless steel by PVD.I tried chlorhydric acid, which can strip CrN but not completely.And I tried alkali and KMnO4,still can not strip the CrN completely.Can anybody give me some advice?
Thanks a lot.

Dear Guillermo Marrufo
ni hao!
Your Chinese is good. Welcome you to come China someday.
Thank you for your advice. I have tried it but didn't get a good result.Maybe because of the different parameter.Whatever, I will do more work.
Thanks again and hope your Chinese will be better and better.
Zai jian.
