Thermal Spray Technologies

Certain interfaces of engine components are coated with thermal barrier, wear, or abradable coatings. As a result of engine operation and heat treatment processes, these coatings need to be replaced periodically. Tungsram Aero Space Power uses a sophisticated thermal spraying system which can create unique coatings with access to different kinds of surfaces and cavities, thanks to robotics solutions.

Moreover, thermal spraying is also applicable for minor dimensional adjustments combined with machining of the coated areas. Hard masks are usually developed to protect adjacent surfaces during the coating process. The performance of the coating can also be tested in a destructive laboratory.
