摘要：As a kind of new concept kinetic weapons with hypervelocity, the electromagnetic railgun has a control technology on the sliding electrical contact between armature/rails. The initial sliding electrical contact belongs to the solid-solid dry friction state, which has a serious impact on the system launch efficiency and the rail life. This paper analyzes the research progress of liquid lubricated and solid lubricated technologies commonly used in the sliding contact of electromagnetic railgun in the initial launch stage. The application of hydrodynamic lubrication technique to electromagnetic railgun was discussed from the aspects of theory basis, preparation process, electro-thermal characteristics, mechanical properties and chemical properties. Finally, the application of low melting point alloy coating to improve the initial sliding contact of electromagnetic railgun was put forward. This article has important significance to the research of electromagnetic railgun technology.
