Titanium-ceramic composites are potential implant material candidates because of their unique mechanical properties and biocompatibility. This review focused on the latest advancement in processing of titanium-ceramic materials. Previously, titanium-ceramic incorporated using different coating techniques, i.e., plasma spraying and electrophoretic depositions, to enhance the biocompatibility of the implants. A major drawback in these coating methods is the growth of tissue at only the surface of the composite and might peel off over time. Recently, metal-ceramic composite was introduced via powder metallurgy method such as powder injection moulding. A porous structure can be obtained via powder metallurgy. Producing a porous titanium-ceramic structure would improve the mechanical properties, biocompatibility and tissue growth within the structure. Hence, further research needed to be done by considering the potential of powder injection moulding method which offer lower costs and more complex shapes for future implant.
钛陶瓷复合材料因其独特的机械性能和生物相容性而成为潜在的植入物材料候选者。本综述重点介绍了钛陶瓷材料处理的最新进展。以前，使用不同的涂层技术，即等离子喷涂和电泳沉积，将钛陶瓷结合在一起，以提高植入物的生物相容性。这些涂层方法的一个主要缺点是仅在复合材料的表面生长组织，并且随着时间的推移可能会剥落。最近，通过粉末冶金方法（例如粉末注射成型）引入了金属陶瓷复合材料。通过粉末冶金可以获得多孔结构。制造多孔钛陶瓷结构可以改善机械性能、生物相容性和结构内的组织生长。因此，需要通过考虑粉末注射成型方法的潜力来进一步研究，该方法为未来的植入物提供了更低的成本和更复杂的形状。
