The method comprising: locally exciting the particles so as to increase the kinetic and/or thermal energy of the particles; and applying pressure to the particles by virtue of a press arranged so as to press the particles against the surface of the prosthetic component at an interface between the press and the prosthetic component. The kinetic and/or thermal energy of the particles causes localised heating of the component such that the particles may be embedded into the surface of the prosthetic component.
