Post deposition heat treatment effects on hydroxyapatite vacuum plasma spray coatings
In the non-cemented femoral prothesis, hydroxyapatite (HA) coatings are currently widely used. If properly manufactured, this kind of prothesis permits a strong and durable joint. It has been noted that the degree of crystallinity of the HA coating is related to the adhesion properties of the ceramic on the substrate with higher crystallinity generally being associated with lower mechanical strength in the HA-substrate system. This work considers the possibility of modifying the crystallinity and the adhesion properties of both high and low crystallinity HA coatings using heat treatments.
