Development of High Functional Coatings by Smart Plasma Spraying Method

Regarding thermal processing, an important key should be the performance of the applied heat source. The plasma is one of the most superior heat sources, because of high temperature, high energy density, easy controllability, etc. The gas tunnel type plasma system developed by the author has high energy density and also high efficiency. It can be applied to various thermal processing. One practical application is plasma spraying of ceramics such as Al2O3 and ZrO2. The characteristics of these ceramic coatings were superior to the conventional ones. The ZrO2 composite coating has the possibility of the development of high functionally graded TBC (thermal barrier coating). Other application of gas tunnel type plasma is plasma reactive spraying of metal Ti. The TiN thick coatings with good quality were formed in a very short time of 10s. Now, advanced plasma spraying methods such as smart coating technology are expected to use the excellent characteristics of ceramics. Typical application of the smart plasma spraying in the formation of the metallic glass coating with high function, and in hydroxyapatite coating for bio-medical application.
