Plasma biocomposite coatings based on copper substituted calcium phosphates
The structure of powders of copper-substituted hydroxyapatite and tricalcium phosphate was studied by X-ray diffraction and infrared spectroscopy. The modes of plasma spray coating on the basis of copper-substituted hydroxylapatite and tricalcium phosphate powders are given, as well as surface treatment technologies before coating. Scanning electron microscopy of plasma biocomposite coatings based on copper-substituted powders was made to reveal the particle sizes of the powder that make up the coating. The chemical composition of coatings based on substituted calcium phosphates is analyzed. The adhesion and hydrophilic characteristics of plasma spraying coatings were studied.
