Abstract

Development in thin-layer diamond-like coatings is a very crucial advance in the field of improvement of biomaterial biocompatibility. Owing to their already investigated properties, diamond-like carbon (DLC) and nanocrystalline diamond (NCD) coatings deposited on implants, which are made of materials that can cause undesirable reactions in the organism, can significantly improve the parameters a spare part of the human body should be characterised by. Diamond-like carbon (DLC) is attractive as a wear-resistant coating for biomedical applications due to its high hardness and low coefficient of friction, chemical inertness and smooth surface finish. One important property of both hard and soft DLC is their biocompatibility, and the potential of DLC coatings for biomedical applications has been extensively reported in the literature. In addition to biocompatibility, this potential is related to the fact that DLC is wear-resistant, smooth/low friction, and inert to chemical attack, and it forms a hermetic coating.

薄层类金刚石涂层的开发是生物材料生物相容性改善领域的重要进展。由于它们已经被研究过的特性，类金刚石(DLC)和纳米晶金刚石(NCD)涂层沉积在植入物上，它们是由可能在生物体中引起不良反应的材料制成的，可以显著改善人体备用部分应该表征的参数。类金刚石(DLC)由于其高硬度、低摩擦系数、化学惰性和光滑的表面光洁度而成为生物医学应用的耐磨涂层。硬质和软质DLC的一个重要特性是它们的生物相容性，DLC涂层在生物医学应用方面的潜力已经在文献中得到了广泛的报道。除了生物相容性外，这种潜力还与DLC耐磨损、光滑/低摩擦、对化学侵蚀不敏感有关，并且它可以形成一个密封涂层。
