摘要: 液态金属作为一种新型材料,通常是指熔点低于200℃的低熔点合金,是一种不定型的、可流动的金属,其中室温液态金属的熔点更低,在室温下即呈液态,正是因为这种不定型的液体形态,使其有着很好的流动性、导热性、热稳定性等性能,目前已经应用于诸多领域。国外在20个世纪就已经开始了对液态金属润滑性能的研究,但国内对液态金属用作润滑剂的研究目前还在起步阶段。介绍了液态金属的制备过程,从液态金属的润滑性能、液态金属的润滑机理和液态金属轴承的工作性能三大方面出发,总结了液态金属用作润滑剂的研究现状,并且提出了我国今后在该研究上的努力方向以及未来使用液态金属作润滑剂要解决的几个问题和技术。

Abstract: As a new material, liquid metal usually refers to a low melting point alloy with a melting point below 200℃. It is an amorphous, flowable metal. The liquid metal at room temperature has a lower melting point and is liquid at room temperature. Because of this amorphous liquid form, it has good fluidity, thermal conductivity, thermal stability and other properties. It has been used in many fields. It has been studied on the lubrication properties of liquid metal in foreign countries since the 20th century, but the research on the use of liquid metals as a lubricant in China is still in its infancy. The preparation process of liquid metals is introduced. From the three aspects of lubrication performances of liquid metals, lubrication mechanisms of liquid metals and working performances of liquid metals bearings, the research status of liquid metal used as lubricant is summarized, and the direction of the research and the problems and technologies to be solved in the future using liquid metal as a lubricant in China is proposed.

Key words: liquid metals, lubrication, working performance, friction, wear, prospect
