Cold spray (CS) is a solid-state additive process, whereby material layers are added onto substrates or more general engineering components through the acceleration of the feedstock material (in the form of powder) up to supersonic speed in a converging–diverging nozzle. Melting temperatures in the process are typically not reached.
Theory and Application
Introduction and Working Mechanism
In the 1980s, a group of scientists from the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (ITAM of RAS) in Novosibirsk, Russia, conducted experimental and theoretical work on the interaction of a two-phase flow with the surface of immersed bodies. They used new gas dynamics diagnostic tools to study two-phase flow around bodies, which resulted in the discovery of some sort of “deposition phenomena.” The scientists had in...
