摘　　要：概述了身管内壁损伤的“热–力–化学”影响及其耦合特性,提出了身管损伤的主要机制,介绍了损伤机制的国内外研究现状。基于这些损伤机制,进一步提出了提升身管寿命的3类技术措施,即抗燃气化学烧蚀、抗弹带摩擦磨损、既抗烧蚀又抗磨损,并分别对每一类措施中的典型方法进行了介绍。具体来说,包括高能低爆温发射药技术、缓蚀添加剂技术、高热强炮钢技术、弹炮匹配设计技术、身管内壁抗烧蚀涂层技术等。文中研究结果可为火炮身管寿命基础理论和寿命提升方法的研究提供参考。The“thermal-mechanical-chemical”factors and their coupling effects on the damage of the barrel are summarized in this paper.The main mechanisms of the barrel damage are proposed,and the research progress on barrel damage at home and abroad is briefly introduced.According to these damage mechanisms,three kinds of techniques,namely,anti-erosion from propellant gas,anti-wear from rotating band,and simultaneous anti-erosion and anti-wear,are proposed to improve the barrel life.Moreover,the typical methods in the said three kinds are described,including new propellant with high energy and low detonation temperature,anti-erosion additives,gun steel with high strength at high temperature,matching design of projectile and gun,anti-erosion coatings,etc.As a result,this paper can serve as a reference for the investigation of fundamental theories of barrel damage and improvement methods of barrel life.
