Abstract
A process is provided for depositing hydroxylapatite on the surface of materials suitable for implantation into animals and humans. In this process, a coating of hydroxylapatite is applied to dental or surgical implants using a sputter technique that employs a high energy ion beam and a negative potential to coat the implant. The process is carried out in a vacuum into which a controlled amount of oxygen is introduced.
