Bioceramic materials based on CaTiZr 3 (PO 4 ) 6 were synthesised by a ceramic route, characterised by XRD and EMPA analyses, and used as a precursor material to coat Ti6Al4V substrates by atmospheric plasma spraying. This led to multiphase bioactive layers with sufficient porosity for medical applications. In‐vitro biocompatibility tests conducted with primary cultures of rat bone marrow cells incubated for two weeks showed that the CaTiZr 3 (PO 4 ) 6 substrates supported a distinctly higher cell growth rate compared with Thermanox™ cell cover slips used as a control.
