| Résumé | Surface coating can be used to enhance and/or optimize the functionalities of medical implants and devices. Laser cladding, a material additive technology, has a potential to apply various functional coatings on the metallic materials for biomedical applications. Two laser clad coatings have been investigated for potential medical implant applications: (1) Ti-6Al-4V alloy coating laser-clad on porous titanium foams; and (2) Composite coating of Ti-6Al-4V combined with CoCrMo alloy laser-clad on solid Ti-6Al-4V substrates. The microstructure of the laser-clad coating was examined by optical microscope (OM) and scanning electron microscope (SEM). Microhardness was measured in the laser-clad coating. Sliding wear testing was particularly performed to evaluate the wear resistance of (Ti-6Al-4V + CoCrMo) composite coating using pin-on-disc wear testing. Initial results show that laser-clad Ti-6Al-4V coating on porous titanium foams is dense and crack-free. The addition of a small amount of CoCrMo alloy will significantly increase the wear resistance of the Ti-6Al-4V composite coating. |
