Ceramic Coatings by Thermal Spraying – a Comparison between High Velocity Oxy-Fuel and Atmospheric Plasma Spraying
Metals, plastics and ceramics each have particular properties, which make them suitable for different applications. Density, thermal and electrical conductivity, thermal expansion, hardness, Young’s modulus, optical properties, melting point, chemical stability, manufacturing cost and environmentfriendliness are only some of the aspects which must be considered in the selection of a material class for a given application. Despite the development of a great number of new materials, a single material may not fulfil all the requirements of the intended application. In many cases, simply the modification of the surface of the structural material by means of a coating is sufficient to improve an existing application or to enable new ones.
