Spraying in a controlled atmosphere produces a coating that is thin, dense, oxide-free, and very pure. Because of these properties, applications include land-based and in-flight turbine components and medical implants. Commonly used materials include metals, ceramics, and cermets.
Controlled atmosphere plasma spraying (ChamPro) refers to coatings applied in a chamber, usually at near vacuum. It applies superior coatings characterized by high densities or very controlled porosities with extremely low contamination. With this method, we can achieve certain results not possible with any other thermal spray process, such as thin layers, ceramic structures, and the application of refractory metals.
