Glass and Ceramics Aims and scope Submit manuscript

The technology for synthesizing fluoromagnesium apatite powder and the plasma-spraying technology for forming a coating based on it are presented. The recommended conditions for forming a coating based on fluoromagnesium apatite powder with open porosity > 40%, adhesive strength 15 MPa, hardness 190 HB and wettability are: arc current 300 A, dispersity of titanium powder up to 150 μm, dispersity of fluoromagnesium apatite powder up to 90 μm, consumption of plasma gas 20 L/min, spraying distance of titanium powder up to 150 mm, and the spraying distance of fluoromagnesium apatite powder up to 50 mm.
