Abstract
The bearing surfaces of joint implants created the need for a specific class of materials that are resistant to wear and corrosion in the environment of the human body, all the while staying biocompatible. Diamond-like carbon (DLC) layers are one of the most prominent solutions, proposed in scientific literature to fill this niche. The ability to dope amorphous DLC structures with atoms that enhance desirable properties or display biological activity further justifies high interest in the topic. This work explores and compares gradient and non-gradient doping with silicon and nitrogen in the case of DLC layers deposited by PECVD (Plasma Enhanced Chemical Vapor Deposition). The scope of this article entails a comparison of morphologies and topographies investigated by SEM and AFM, differences and similarities in chemistry are emphasized with the help of FTIR, Raman and XPS spectroscopy. Relevant mechanical (Young's modulus, hardness) and tribological (coefficient of friction, wear) properties are measured and paralleled in the case of gradient and non-gradient Si:DLC/(Si,N):DLC layers. Superior hardness of gradient DLC layers was proven with (Si,N):DLC layer showing the best result (17.9 GPa), compared to non-gradient equivalent (13.6 GPa). Additionally, gradient Si:DLC layer and silicon gradient (Si,N):DLC layer showed lower coefficient of friction (down to 0.14) and wear (down to 5.37·10−6 mm3/N·m), in comparison to non-gradient equivalents.
