| Abstract: |
Detonation spraying is used for applying metal, cermet, polymer and ceramic coatings. The advantages of this technology include good adhesion and density of coatings. Minimal residual stresses in the spray process give the possibility to apply coatings to thin-walled parts and foil. The new design of the detonation spraying system allows its use for additive manufacturing of 3D parts with near sub-micron structure in hybrid processes. This result was obtained due to a new design of the valve head, new computer control system, electronics and software that allows to increase the firing rate frequency and ensure the reliability. Numerical modeling methods of the energy parameters of the powder particles enable to predict the interaction of the particles with the gas flow and the properties of the parts.
