摘要：

Diamond coating on steel by microwave plasma chemical vapour deposition (MPCVD) is investigated. Direct growth of diamond film on steel substrate is possible, but its adhesion is poor because of the formation of a rather thick graphite layer at the diamond/steel interface. Calculation is performed in order to select a suitable interlayer. The results show that titanium is one of the promising candidates. Under optimized process conditions, adherent diamond film is coated on the steel with a titanium interlayer approx. 2 mu m thick. Pull-off tests and micro-indentation tests are performed to evaluate the coating adhesion. (C) 1998 Elsevier Science S.A.
