Physical and mechanical properties of hydroxyapatite plasma sprayed materials applied in implantology

Abstract

Background The research involved the evaluation of physical and mechanical properties of hydroxyapatite (HAp) bio-ceramics sprayed on titanium substrate of the type Ti-grade 2 (CP-Ti) by means of the plasma method. An innovative method of coating is applied when using implantology for healing bone defects in the body. Material and Methods Hydroxyapatite coating was prepared in order to conduct research. The powder was made using wet-chemical technology consisting in separating the solids from the solution. Next, a titanium substrate was prepared, onto which hydroxyapatite was applied with a plasma technique. Results As a result of the research it has to be noted that the properties of the obtained coating may be used for covering large surfaces of implants of any shape. Conclusions During the research into the physical and mechanical properties of hydroxyapatite composites it has been observed that they show sufficient mechanical properties to be used in implantology. The further aim of the research will involve selecting technological parameters of spray coating in order to increase adhesion and cohesion of HAp coatings. Med Pr 2018;69(6):651–661
