Stripping/Ashing of DLC (diamond-like carbon) Coatings
Q. I am looking for a method to strip DLC with Ti underlayer on a 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 is there any other experience success in doing this?

A. DLC coatings with an 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.

RFQ: We have some Tungsten Carbide parts coated with Diamond-like-carbon(DLC) coating. As time goes on, we will periodically need to peel off this DLC coating--without damaging the tungsten carbide surface. I heard of a method of ashing-off the carbon coating. Do any of you know such a place that provides this service? Your responses are highly appreciated.
Thanks in advance.
