| Abstract: | This paper compared serveal technologies for preparing the metal/ceramic composite coatings by laser cladding and reviewed the materials system for these coatings. It concentrated on the analysis of ceramic phases in the wear-resistant metal/ceramic composite coatings and their wear mechanisms in different working regimes,including abrasive wear, sliding wear and fatigue wear,and discussed preliminarily also the behavior of ceramic particles in laser cladding process and its effect on the properties of coatings. Eighteen papers were reviewed. |
