ABSTRACT:
A method for removing nitride coatings from metal tooling and mold surfaces without damaging the underlying base metal includes placing the nitride coated metal surface into a plasma reactor and subjecting it to a gaseous plasma comprising a reactive fluorine species. The reactive fluorine species may be derived from one or more of many well known gases. An optional step of cleaning the nitride coating is recommended.
