How to strip TiAlN from high speed steel

How to strip TiAlN form high speed steel? I'm using H2O2 +NaOH +H2O + EDT, but the time is long ( > 10 hours).

Dear Ronaldo Ruas,

hi!

Have you tried different proportions of the alkaline and H2O2? In my experience, it can decoat the coating is not very long. Maybe because of your coating's thickness.

By the way, I am a crazy football fan of Inter Millan and Argentina, so your name is really sensitive to me. I am kidding of course :)
