摘要

钛合金，尤其是 Ti6Al4V，作为关节植入材料已得到广泛认可。针对 Ti6Al4V 植入材料在实际应用中存在的摩擦力大、易感染等问题，提出了一种对 Ti6Al4V 进行表面改性的策略。受关节软骨的启发，这项工作制备了一种集润滑和抗菌特性于一体的坚韧水凝胶，并用粘合剂将其紧密涂覆在 Ti6Al4V 表面。水凝胶涂层的强度与人体关节软骨的强度相近，同时具有显著的润滑和抗菌效果。这项研究为水凝胶涂层在生物医学、水下设备、智能操控等领域的应用提供了新的视角。

Improving the lubricity of titanium alloy joint by using tough, antibacterial and strongly adhesive hydrogel

Titanium alloy, especially Ti6Al4V, has gained widespread recognition as a material for joint implant. Aiming at the problems such as high friction and easy infection of Ti6Al4V implant materials in practical applications, a strategy of surface modification of Ti6Al4V was proposed. Inspired by the articular cartilage, a tough hydrogel integrated with lubricating and antibacterial properties was prepared in this work, and tightly applied to the Ti6Al4V surface with an adhesive agent. The strength of the hydrogel coating was similar to that of human articular cartilage, and play remarkable lubricating and antibacterial effects at the same time. This work presented new perspectives on the application of hydrogel coatings in biomedicine, underwater equipment, smart manipulation, and other fields.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
