Opis:: The aim of this paper is to report the results of field emission experiments on undoped, flat diamond-like carbon (DLC) thin films deposited at various self-bias voltages using radio frequency plasma chemical vapor deposition (RF PCVD) technique. It has been observed that the emission properties improve when the absolute value of self-bias voltage becomes higher, e.g., the turn-on field value decreases. The correlation between electron field emission and sp2 content in these films showed improvement of electron emission properties of DLC films for higher amount of sp2 phase.

Opis:: Co-Cr and Ni-Cr alloys are widely used in dental implants production. However, there is a risk connected with application of this kind of materials like allergy and methalosis caused by Cr, Ni ions, very dangerous for patients’ health and life. Moreover metal ions released into human body can affect inflammation of the surrounding tissue. Biomaterials’ surface treatment by the deposition of diamond-like carbon films can noticeably improve the corrosion and mechanical features. Widely discussed in world’s literature problems with adhesion of DLC layers can be solved by the deposition of gradient a-C:H/Ti layer. Due to that, it is possible to manufacture thick and well adherent carbon layer on the implant’s surface which will constitute a very good protection against wear and corrosion. Our goal was to evaluate the mechanical properties of a-C:H/Ti layers deposited on CoCr and NiCr alloys in hybrid deposition system RF PACVD/MSand to find the influence of layer thickness on the selected properties. As the result of the investigation it was noticed that deposition of a-C:H/Ti layer improves the mechanical properties of CoCr and NiCr alloys. High hardness and good adhesion of gradient carbon layers makes them a very perspective material for this kind of applications.
