Abstract
Ti–Ca–P bioceramic composites for load bearing implants developed by a new powder metallurgy processing technique were studied for their electrochemical corrosion properties. For determining corrosion behavior of such composites having in situ formed bioactive Ca–P phases, potentiodynamic and studies were conducted in simulated body fluid namely Hank's balanced salt solution. Potentiodynamic polarization tests showed no evidence of pitting corrosion. Corrosion potentials (−0.27 to −0.53 V) and corrosion rates (0.17–4.46 mills per year) of Ti–Ca–P bioceramic composite samples were superior to earlier reported results for coated Ti implants due to the formation of passive layer of bone‐like calcium phosphate on the sample surface.
