Abstract
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.
