The current state and future trend of laser bio-cladding technology are discussed. Laser bio-cladding
is used in implants including fabrication of metal scaffolds and bio-coating on the scaffolds. Scaffolds have
been fabricated from stainless steel, Co-based alloy or Ti alloy using laser cladding, and new laser-deposited Ti
alloys have been developed. Calcium phosphate bioceramic coatings have been deposited on scaffolds with
laser to improve the wear resistence and corrosion resistence of implants and to induce bone regeneration. The
types of biomaterial devices currently available in the market include replacement heart valve prosthesis, dental
implants, hip/knee implants, catheters, pacemakers, oxygenators and vascular grafts. Laser bio-cladding
process is attracting more and more attentions of people.
