| Abstract: |
| Lase cladding fabrication of hydroxyapatite (HAP) bioceramic coatings on titanium has become one of the research hotspots in the field of biomedical implant materials and relevant fields worldwide in recent years. Firstly, characteristics and meanings of HAP bioceramic coatings were summarized; historical development and characteristics of biomedical titanium metal and bioceramic were introduced; advantages and disadvantages of bioceramic coatings fabricated by adopting existing technologies in preparation and application were pointed out; and features and merits of the bioceramic coatings fabricated by laser cladding were introduced. In addition, research features, current situation and progress were reviewed for HAP bioceramic coating, laser rapid forming bioceramic coating and relevant materials fabricated by laser cladding on Ti alloy at home and abroad. Features as well as merits and demerits were emphatically introduced for laser cladding of different raw materials, fabrication mechanism of bioceramic coatings with rare earth at different wavelength, and laser cladding fabrication of bioceramic coatings. Laser cladding fabrication of bioceramic coatings and relevant materials is a research field involving multi-crossed disciplines. Based upon laser surface modification of titanium alloys, laser cladding fabrication of bioceramic coating has broad prospect in terms of theory research and clinical usage. Future research fields of HAP bioceramic coatings being fabricated and synthesized by laser cladding process were discussed and prospected. |
