| ABSTRACT Diamond-like carbon (DLC) layers due to their good mechanical properties are a very interesting material for many industrial applications. But to thick DLC layer results in high internal stress, and is the reason of problems, connected with their poor adhesion and self delamination processes. This problem is widely discussed in world literature. Despite of their very good friction parameters very often the maximum thickness possible to obtain is not sufficient to be applied. Authors of this work propose improvement of adhesion and increase of the thickness of carbon layers by the deposition of Ti inter and buffer layer between the substrate surface and the carbon layer on the top. Specially to that purpose a new apparatus was designed, which is the connection of impuls magnetron sputtering and plasma assisted chemical vapor deposition in one reaction chamber. Gradient layers were deposited on typical materials which are used in automotive industry and work under friction conditions. Manufactured layers were investigated on SEM and AES, friction coefficient and wear resistance was measured by ball – on – disc method. As the result of investigation it was noticed that carbon layers manufactured in new deposition system are very promising material for automotive applications. It was possible to obtain thick and well adherent DLC layers with keeping of their very good friction parameters. | ||
