Hi, Ghataliya. Please tell us the procedure you are using that you are finding unsatisfactory because it takes more than an hour.

Sorry that no one answered you, but it's probably because nobody wants to spend their time carefully writing up a procedure for you which you may well instantly dismiss, saying "that's what we do; it takes too long" :-)

Please start by describing what you are presently doing. Thanks!

It is possible to de-TiN using electrochemical method. Use TiN coated material as anode and another material as cathode.
