Suspension detonation spraying of ceramic coatings

Experiments on detonation spraying of ceramic coatings are carried out by feeding a powder as part of a suspension into a barrel for the first time. Spraying of $\mathrm{Al}_2\mathrm{O}_3$ and $\mathrm{TiO}_2$ nanopowders and hydroxyapatite shows that the new method for obtaining coatings (suspension detonation spraying) can be implemented on a CCDS2000 detonation device. Unlike conventional detonation spraying technologies using micron-sized powders, suspension spraying makes it possible to work with powders whose particle size is smaller than 1 $\mu$m, serving as a basis for a suspension fed into the projector barrel during spraying.
