摘要：
Titanium boronitride coatings were deposited by reactive magnetron cosputtering. The Ti and the TiB2 targets were sputtered by using an Ar-N-2 gas mixture. The deposition configuration allowed us to obtain a composition gradient along the substrate length. The coatings have been characterized by reflectivity measurements and X-ray diffraction while, for mechanical applications, scratch tests, hardness indentations and wear tests were used. The zone explored in the Ti-B-N diagram shows very different behavior with chemical composition. Coatings 10 mu m thick with 6000 HV hardness exhibit wear rates nine times lower than those of TIN coatings. (C) 1997 Elsevier Science S.A.
