ABSTRACT:
Methods and compositions are provided for coating a substrate with a strongly adherent hydroxyapatite coating, which allows for ingrowth of natural bone and strong bonding between the coating and the substrate. The procedure provides for repetitive coatings at varying concentrations of coating forming reagents, where the highest concentration is used initially. The coating has particular application for prostheses, where porous areas of the prostheses are completely coated with a thin sturdy coating of hydroxyapatite.
