Abstract
A process for coating a surface of a metal-containing substrate with a bioceramic material includes activating the surface of the metal-containing substrate by applying a voltage to the substrate in a liquid containing an electrolyte; and, immersing the substrate in a deposition solution containing the bioceramic material or precursors for the bioceramic material. The coated substrate may be heat treated to enhance coating bond strength. The bioceramic material may be hydroxyapatite. Coated substrates are useful for the fabrication of prostheses.
