摘　　要：轨道材料的性能是决定电磁轨道炮工程应用的关键因素。在大载流、高温的苛刻工况下,表面刨削、转捩和电弧烧蚀以及载流摩擦磨损是电磁轨道表面的主要损伤形式。综述了电磁炮轨道刨削现象及其产生原因和微观机理的研究现状,总结了转捩和电弧烧蚀对轨道性能的影响,概括了电磁轨道炮中载流摩擦磨损的特点,为开发新型轨道材料提供依据和借鉴。The performance of rail materials is the key to the application of the electromagnetic rail-gun.Under high carrier current and high temperature,the main surface failure forms of the electromagnetic rail are surface gouging,transition and the arc erosion,the current carrying friction and wear.This paper reviews the phenomenon,reasons and microscopic mechanism of gouging.A comprehensive summary of transition and arc erosion are expounded.The characteristics of current carrying friction and wear in the EM rail-gun are also summarized.The aim is to provide basis and reference for the development of new rail materials.
