Abstract
Peculiarities and characteristics of the method of microplasma spraying allowing a reduction of up to 5-15 % in powder losses in spraying on small objects are given. The process of production and properties of microplasma coatings of bioactive ceramics, i.e. hydroxyapatite (HA) are investigated. Phase and structural transformations occurring in the HA particles during their heating in a microplasma jet and conditions of formation of the coatings are studied. The feasibility of spraying HA coatings with a low degree of dissociation and amorphization is shown.
Keywords: microplasma spraying, hydroxyapatite, process parameters, spraying spot, phase composition, investigations
