Cell adhesion on biomaterial surfaces with nanocomposite oxide coatings

Abstract

Deposition of functional coatings is one of the most optimal ways of surface modification enabling an efficient control of stoichiometry, impurity elements, functional groups and surface charges. Nanocomposite coatings based on Al, Zr, Ti oxides exhibit unique properties: high inductivity, density, bio-and chemical inertness [1-3], which are very important for subsequent implant and tissue engineering applications. Corrosion is one of the major processes that cause problems when metals and alloys are used as implants in the body [4]. Corrosion of implants in the aqueous medium of body fluids takes place via electrochemical reactions [5], and it is necessary to understand the electrochemical principles that are most relevant to the corrosion processes. The body fluid environment may well decrease the fatigue strength of the metal implant and enhance the release of iron, chromium, nickel,

The improvement of tribological parameters of nano structural multilayer coatings for unipolar modular joint applications

“…The application of metal materials with ceramic coatings is the effective way of alternative bearing surfaces formation. The ceramic aluminum nitride AlN, aluminum oxide Al 2 O 3 and nano composite oxynitride coatings are widely used as protective coatings against wear, diffusion and corrosion [22][23][24]. The enhancement of mechanical properties such as hardness parameters, effective Young's modulus, and toughness of the coatings is very important for tribological performance of the next generation of ceramic-coated femoral heads of modular and total joints.…”
