Stripping of DLC with Ti underlayer
+++
I am looking for a method to strip DLC with Ti underlayer on the
stainless substrate. I tried to used concentrated HF solution, but
there is no chemical stripping action even after an hour! Some people
say burning DLC at high temperature can do this, but are there any
other experience success in doing this?

DLC coatings with underlayer of Ti can be stripped by reactive ion
etching. The process is a reactive plasma based process and is very
successful in removing the DLC coating and metal underlayers without
ruining the substrates. Some post removal polishing may be required,
but it would be minor.
