Heat and Mass Transfer in Formation of Diverse-Function Coats by a Supersonic Heterogeneous Flow
RÉSUMÉ
The paper presents the laws governing the mechanism of the formation of surface coatings by the low-temperature gas-dynamical method. It is shown that the level of the kinetic energy of the particle plays a deterministic role in the process of coating formation by a supersonic two-phase flow. The required magnitude of the kinetic energy depends uniquely on the kind of a coating, its predictable properties, and the properties of the substrate. The analysis of the dynamics of collision between a hard particle and an obstacle is carried out for a velocity of particles of about 1000 m/sec. An equation of energy balance (in the zone of impact) is derived and solved.
