1船舶水润滑尾轴承服役性能研究及其进展显示文摘尾轴承是船舶推进轴系的关键部件,近年来水润滑尾轴承的研究有新的进展。在润滑水黏度低、载荷环境复杂(重载、边缘负载和不确定性负载)、低速、启停和沙粒侵扰等恶劣工况条件下,尾轴承的承载机理复杂、磨损严重和摩擦噪声大。从船舶水润滑尾轴承的特点出发,围绕其性能演化与防治机理,就承载机理和模型、试验技术、摩擦磨损机理和预测方法、异常摩擦噪声机理及性能提升措施等五个方面,综合分析船舶水润滑尾轴承的研究进展,指出尚待解决的问题和今后的研究方向。严新平 梁兴鑫 刘正林 周新聪 袁成清 欧阳武 2017中国造船2017,58,3:20

4Regulation mechanism of biomolecule interaction behaviors on the superlubricity of hydrophilic polymer coatings显示文摘Hydrophilic polymer coatings can improve the surface characteristics of artificial implants.However,because they are used in vivo,they inevitably come into contact with biomolecules that affect their interfacial tribological properties.In this paper,the friction behaviors of poly(vinylphosphonic acid)(PVPA)-modified Ti6Al4V and polytetrafluorethylene balls were analyzed using albumin,globulin,aggrecan,and hyaluronic acid as lubricants.The interaction properties and dynamic adsorption characteristics of the biomolecules and PVPA molecules were explored by a quartz crystal microbalance to identify the cause of the friction difference.It was found that protein molecules disturbed the superlubricity of the PVPA-phosphate-buffered saline system because of the formation of a stable adsorption film,which replaced the interfacial characteristics of the PVPA coating.Polysaccharides,with their excellent hydration properties and polymer structure,had an unstable dynamic interaction or zero adsorption with PVPA molecules,and hardly changed the superlubricity of the PVPA and phosphate-buffered-saline system.The influence mechanism of the specific friction of proteins and polysaccharides was analyzed.Interactions were observed among different biomolecules.Polysaccharides can potentially reduce protein adsorption.The result of the synergistic regulation of the friction coefficient for PVPA-modified Ti6Al4V is approximately 0.017.The results of this study will provide a theoretical basis for the use of polymer coatings in vivo.Caixia ZHANG Junmin CHEN Mengmeng LIU Yuhong LIU Zhifeng LIU Hongyan CHU Qiang CHENG Jianhua WANG 2022Friction2022,10,1:0
