Abstract
A technique for plasma spraying of a magnesium-substituted tricalcium phosphate powder has been developed; optimum modes of the plasma-jet arc current and the particle size of the sprayed powder have been determined. It has been found that the structure of the resulting coating contains microparticles and nanoparticles with a size of up to 90 μm and up to 100 nm, respectively. The adhesion of the substituted coatings is 13 MPa; on average, it is 20% higher than the adhesion of coatings based on unmodified powders.
