Abstract:
Hybrid metal-ceramic or metal-polymer nanocomposite layers containing dispersed second-phase particulates usually have various special properties such as dispersion hardening, self-lubricity, high temperature inertness, good wear and corrosion resistance, or tribocorosion resistance and chemical compatibility. This accounts for the increased application of metal-based hybrid nanocomposite in industry applications and opens also a way to biocompatible films. In order to meet the requirement for developing novel metal-based hybrid nanocomposite, many preparation techniques have been investigated. As a technique conducted at a normal pressure and ambient temperature and of low cost and high deposition rate, electrodeposition is considered to be one of the most important techniques for producing hybrid and nanocomposite coatings with micro or nano structured surfaces. Electrodeposition is exceptionally versatile, so that new and exciting applications are still being invented. The paper presents some challenges and some results regarding the electrodeposition of nano bio ceramic dispersed phases as CeO2,TiO2,TiC, or polymeric dispersed phases as UHMWPE (ultra high molecular weight polyethylene) during cobalt or nickel electroplating processes in view of obtaining bio composite layers or resistant industrial hybrid coating applications.
The micro and nano particles incorporation into the metal matrix by electrodeposition usually causes a noticeable grain refinement and thus an increase in the corrosion and tribocorrosion resistance of hybrid or nanocomposite layers obtained in aqueous or in vitro simulating body fluids (SBF) specific environments.
