Resum
Plasma-sprayed hydroxyapatite coatings were used for many years to improve the osseointegration of joint implants. However, it was observed that their mechanical properties did not meet the requirements. Consequently, as in previous studies, an HAp-TiO2 mixture was considered. But, contrarily to these studies, where TiO2 is the majority phase (80-90 wt.% into the mixture), in this work the feasibility of coatings containing only 20 wt% Of TiO2 is proposed. Composite coatings were obtained via hi...
