摘要

涂层人工关节植入物及其周围的组织液是一个固-液系统，该系统的摩擦学行为是评价人工关节植入物使用性能的重要因素，一直受到人们的关注。在这里，我们研究了ZrN-Cu薄膜在牛血清白蛋白（BSA）溶液中的摩擦学行为。结果表明，Cu能有效改善ZrN-Cu/BSA体系的摩擦学性能。通过对摩擦化学产物、吸附行为、赫茨接触应力、闪变温度等方面的研究，阐明了ZrN-Cu/BSA体系的改进机理，具有催化活性的ZrN-Cu膜形成了源自BSA的碳基转移膜，Cu分离了接触面形成了稳定的表面吸附层。

Adsorption behavior regulates the frictional response of a solid-liquid system: A case study of the ZrN-Cu/bovine serum albumin solution system

Coated artificial joint implants and the surrounding tissue fluid are a solid-liquid system, and the tribological behavior of this system is an important factor to evaluate the service performance of the implants, which has received continuous attention. Here, we investigated the tribological behavior of ZrN-Cu films in bovine serum albumin(BSA) solution. The results show that Cu can effectively improve the tribological performance of the ZrN-Cu/BSA system. Through the investigation of the tribochemical products, adsorption behavior, hertzian contact stress, flash temperature, etc., we elucidated the improving mechanism of the ZrN-Cu/BSA system, forming a carbon-based transfer film deriving from BSA with the catalytically active ZrN-Cu film and a stable surface adsorption layer due to Cu separating the contact surface.

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.
