Abstract
A process for attaching a porous layer to a substrate adapted to form the core of a hip prosthesis, the substrate is placed in a cavity in a mould. Spherules are introduced into the space between the substrate and the walls of the cavity. The mould is placed in a furnace, which is heated to a temperature at which the material of which the substrate is made is superplastic. Then a pressure of the order of 10 to 30 MPa is applied to the mould, enabling the spherules to be encrusted on the substrate at a relatively low temperature.
