This is an explanation of thermal spraying terminology.
Alumina (aluminum oxide) is an oxide of aluminum. Abradable spraying is a thermal spraying process conducted to obtain a coating with a property that allows it to be easily abraded. An example of its application is spraying onto the inner wall of a case opposing the turbine rotor to optimize the gap between the rotor and the case. Abrasive wear is a form of wear primarily caused by the cutting action of hard particles interposed between the uneven surfaces in contact. Electric arc spraying is a thermal spraying method that generates an arc between two linear metal spraying materials, and the metal droplets produced by the heat are atomized and accelerated by a jet of compressed air to be sprayed onto the substrate to form a coating. Yttria (yttrium oxide) is an oxide of yttrium. For more details, please download the catalog.
