Abstract: A new approach was developed for surface modification of metallic surface. By treating nano-zirconia particles and metal surface in different charge state, nano-zirconia particles can be dispersedly inlaid in metal surface owing to electrostatic and nanometer effects. By using this method, metal components of complex shapes, especially those having inside surfaces, might be easily improved, i.e., enhanced surface hardness and wear rate.

Abstract: A new method of plastic forming was carried out for zirconia ceramics, which was based on more uniformly mixed and de-agglomerated pastes produced by a process thatinitial dispersion of suspension and subsequent coagulated at a sufficient high solid loading. Through comparing of three approaches or conditions, our results proved that this plastic forming process can give rise to components of higher strength compared to those produced by existing processing route.
