弹丸(主要是弹带)与炮管膛面的相互作用是引起炮管磨损烧蚀的重要原因之一。因此,国外在研究炮管磨损烧蚀的热、机械和化学过程时,也对弹丸与炮管膛面相互作用的机理作了不少研究工作,以便减小弹带的嵌入压力和弹带材料与膛面的相互作用。本文简要叙述美国的一些研究情况,包括弹带的摩擦和磨损特性,炮口磨损的特点与机理,黄铜(90％
The interaction between the projectile (mainly the elastic band) and the barrel bore surface is one of the important causes of ablation of the barrel. Therefore, when studying the thermal, mechanical and chemical processes of ablation of barrel wear, many researches have been done on the mechanism of the interaction between the projectile and barrel bore in order to reduce the embedding pressure of the elastic band and the material of the elastic band Interaction with the breech. This article briefly describes some of the research situations in the United States, including the friction and wear characteristics of the elastic band, the characteristics and mechanism of muzzle wear, brass (90%
