Metal and ceramic materials have their own unique excellent performance and obvious performance weaknesses, how to metal and ceramic materials, the advantages of their respective advantages, has been the material science and engineering research direction. Metal ceramic composite coating technology, that is, the plastic matrix evenly distributed with the shape of particles, the size of the appropriate ceramic phase, the successful realization of the advantages of metal and ceramic combination, the preparation of both the strength and toughness of metal, but also ceramic high temperature , Wear-resistant, corrosion-resistant and other advantages of composite materials, greatly broadening the metal materials and ceramic materials, their respective applications in the aviation, aerospace, chemical, mechanical, power and other industrial applications have been successful [20] [21]. In the industry, the most widely used metal-ceramic coating are: Cr3C2-NiCr, WC-Co. Most use HVOF, plasma and explosive spraying process.
