Performance and Economic Characteristics of Multi-Chamber Detonation Sprayer Used in Thermal Spray Technology

This paper describes the basic design and operation of a multi-chamber detonation sprayer (MCDS) and explains how it differs from conventional detonation sprayers and other spraying methods. It presents and analyzes ceramic, metal, and cermet coatings produced with the new sprayer, highlighting its ability to deposit low-melting point and refractory materials. It compares the efficiency and operating costs of the MCDS with some of the more common HVOF torches and reviews the coating properties that have been achieved with different powders and spraying parameters.
