The deposition of a biocompatible calcium phosphate coating on the surface of materials for biomedical implants by rf-magnetron sputtering is reported.

Crystalline hydroxyapatite coating with a Ca/P ratio of 1.60 ± 0.07 can be deposited if the rf-power density is 0.49 W cm2 and if the samples are arranged within the area of the target erosion zone. A thorough investigation of the influence of rf-power, DC-bias on the substrate, deposition time on the properties of the calcium phosphate coating allowed to formulate a mechanism for the film growth.
