SEM analysis of plasma-sprayed hydroxyapatite coatings obtained with induction preheating of titanium substrate

Abstract

Production of biocompatible nano-ceramic coatings is one of the major goals in prospective materials technology, particularly, in biomedical items, e.g. intraosseous implants and joint endoprostheses. Ceramic coatings obtained by the existing methods do not have the required structural properties of biocompatibility, which causes quality reduction. It has been stated that thermal induction preheating of substrate ensures the required structural organization of hydroxyapatite coating, grain size and shape in particular.
