US6025536A
An orthopaedic implant is forged from a metallic body consisting of a cobalt-chromium alloy. The forged implant is descaled by blasting the implant with a particulate blasting agent at a momentum which is sufficient to remove scale formed on the implant during the forging step but insufficient to otherwise cause major structural surface deformation to the implant.
