Researching of the structural and morphological characteristics of coatings based on metal-containing calcium phosphates

Structural and morphological characteristics of plasma-sprayed coatings on a titanium base, using powders of zinc-, magnesium-containing calcium phosphates, were studied by optical and scanning electron microscopy. The coatings consist of deposited particles with a size of 50 - 150 μm. The particles form agglomerates of 200 μm or more. Using such modes of plasma spraying of powders of metal-containing calcium phosphates as: plasma arc current - 300-350 A, spraying distance - 50-100 mm, powder dispersion - up to 90 μm, transport gas consumption - 5-7 l / min, it is possible to form a uniform coating.
