Effect of the Plasma Deposition Parameters on the Properties of Ti/TiC Multilayers for Hard Coatings Applications

Abstract:

Titanium carbide (TiC) hard coatings have been obtained on steel and silicon substrates by r.f. magnetron sputtering process. Two layer coatings have been deposited in order to improve adhesion on steel. The lower layer was titanium metal and the upper TiC layer was obtained by reactive sputtering of the titanium target in Ar and methane gas mixture. The study confirmed that the TiC layer composition depends on the reactive sputtering gas composition. Film microhardness was measured by microindentation. Measurement results showed that high hardness coatings can be prepared at a relative low concentration of methane in gas mixture and that good adhesion on steel is achieved with the two layer coating.
