Pulse-Detonation Thermal Spray

Abstract

In this article, thermal spray is explained first. The fundamental processes included in thermal spray and the classification of thermal-spray methods are described. Next, the detonation mode of combustion, the pulse-detonation technology, and the properties of the pulse-detonation thermal spray are explained. Also, some detonation guns for thermal spray developed in the past are introduced. After that, thermal-spray experiments carried out on a daily basis in Hiroshima University are introduced. Additionally, new technologies developed for the pulse-detonation guns for thermal spray in Hiroshima University are described. Finally, the past development and present status of the pulse-detonation technology are briefly discussed by using the Hype Cycle.
