Abstract | ||||
ABSTRACT This paper is devoted to recent accomplishments in basic and applied research on gaseous detonation guns for thermal spraying. The conditions of processing powder materials are governed by the thermal, velocity, and chemical relaxation of particles in a high-temperature two-phase pulsed stream generated at every working cycle of the gaseous detonation guns (GDG). The relaxation of particles is conditioned by the parameters of the entire system under consideration and depends not only on the energy of a single pulse and the parameters of the high-temperature gaseous medium, but also on the spatial arrangement of a fresh gas charge and a single dose (metered amount) of powder. The classification and design concepts of detonation guns are discussed. The possible versions of D-guns operation cycle are described. The better understandings of knowledge of the involved phenomena are necessary for improvement of the design of gaseous detonations guns. | ||||
