Metallic Ceramic Particles

There are a wide range of ceramic coating materials that can be applied to metal components in order to enhance their functional properties.

Metallic ceramic particles.

The effect of the ceramic particle velocity. Most ceramic coatings are electrically nonconductive making them excellent insulators have a significantly higher level of abrasion resistance than most metals and are capable of maintaining their integrity under severely elevated temperatures sometimes up to 4 500 degrees fahrenheit. This makes it possible to combine the low weight of the metal with the resistance of ceramics. However these materials have some disadvantages such as low ductility poor wettability particle matrix debonding presence of porosity or particle clusters.

Hard ceramic particles are normally used as reinforcements in the metal matrix. The spectrum of applications for light metal components is growing more and more especially in automotive engineering. Third body débris such as metallic particles pmma cement or even cortical bone can be entrapped between the articulating surfaces of the prosthesis causing abrasive wear of both the soft uhmwpe and the hard surface of the femoral head metal or ceramic 29. In composite materials made from metal and ceramics a metallic substrate material is reinforced with ceramic hardened particles.

Abstract and figures in this paper metal ceramic coatings are cold sprayed taking into account the spray parameters of both metal and ceramic particles.
