This Small Business Innovation Research (SBIR) Phase I project proposes to investigate a new coating for artificial knee replacements, using nano-ceramic materials. The proposed nanoceramic artificial joints, with the wear surfaces containing ceramic coating against ceramic coating, are expected to be superior in wear resistance to a CoCrMo alloy against ultra high molecular weight polyethylene ("UHMWPE") pair. Also, the metallic substrate will provide considerably higher strength and toughness compared to UHMWPE - ceramic combination, thereby avoiding brittle fractures. This project will select a suitable nanocoating composition using a plasma spraying technique for follow on in-vitro evaluation and physical property characterization.The commercial application of this project is in the area of prosthetic devices. This project will allow for the development of artificial prostheses for the knee, hip, elbow, shoulder and other joints, as well as for treatment of osteoporosis and sports related joint damage.

这个小型企业创新研究 (SBIR) 第一阶段项目提议研究一种使用纳米陶瓷材料的用于人工膝关节置换的新型涂层。所提出的纳米陶瓷人工关节，其磨损表面包含陶瓷涂层与陶瓷涂层，预计在耐磨性方面优于CoCrMo合金与超高分子量聚乙烯(“UHMWPE”)对。此外，与 UHMWPE-陶瓷组合相比，金属基材将提供更高的强度和韧性，从而避免脆性断裂。该项目将利用等离子喷涂技术选择合适的纳米涂层组合物，进行后续体外评估和物理性能表征。该项目的商业应用是在假肢装置领域。该项目将开发用于膝、髋、肘、肩和其他关节的人工假肢，以及治疗骨质疏松症和运动相关的关节损伤。
