The influence of substrate morphology on the structure and composition of rf sputter deposited calcium phosphate thin films

摘要

Calcium phosphate bioceramics are widely used as bioactive coatings on hard tissue implants. Their presence as relatively thin films has significant advantages for the stability of the coating during the important osteoconductive phase. RF magnetron sputtering is one of the techniques favoured for the deposition of such films, due primarily, to its ability to provide a high degree of process control. Hence, the properties of the films can be manipulated, such that, the resultant chemistry and morphology engenders a favourable tissue response.
