受松质骨结构和关节软骨营养代谢的启发，我们提出了合成关节软骨类材料的新概念。这种仿生材料即使在超高载荷下也具有低摩擦系数，并具有极长的寿命。此外，复合材料表现出零磨损行为，对摩擦副的磨损损伤可以忽略不计。优异的摩擦学性能归功于自发生成的关节软骨样层，它不断地由摩擦、热和压力补充。我们的发现为工业规模增强应用于改善运动部件的摩擦磨损性能开辟了新的领域。
Inspired by the structure of cancellous bone and the nutrition metabolism of articular cartilage, we present a novel concept for a synthetic articular-cartilage-like material. The bioinspired material possesses a low coefficient of friction even under ultrahigh loads and has an extremely long lifetime. Furthermore, the composite shows zero-wear behavior and causes negligible wear damage to the friction pair. The superior tribological performance is attributed to the spontaneously generated articular-cartilage-like layer, which is constantly replenished by frictional;heat and pressure. Our findings open a new area for industrial scale engiheering applications to improve the friction and wear properties of moving components.
