ABSTRACT:
A porous metal coated implant is produced by diffusion bonding metal powder particles, preferably spherical or flattened spherical metal powder particles of commercially pure titanium grade, in the form of an insert or pad to a substrate, preferably commercially pure titanium or Ti 6Al-4V ELI, a prosthesis, below the beta-transus of the substrate material, under pressure and temperature in a non-reactive atmosphere, such as vacuum. The use of pressure permits bonding temperatures to be reduced to approximately 50% of the melting point of the substrate material. A clamping mechanism for applying pressure to the components is also disclosed.
