Abstract

Experiments on detonation spraying of ceramic coatings are for the first time carried out by feeding a powder as a part of a suspension into a barrel. Spraying of Al2O3, TiO2, and hydroxyapatite nanopowders 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 a micron and which serve as a basis for preparing a suspension injected into the detonation device barrel.
