一、简 述 弹丸和高温、高压的火药气体对枪炮身管内膛的机械、物理、化学作用,使内膛烧蚀磨损,弹道性能下降,最终导致身管寿命终止。近年来,随着枪、炮战术技术性能的提高,身管内膛烧蚀日趋严重,因此对烧蚀机理、降烧蚀技术以及相应的测试技术的研究工作提出了更高的要求。 First, a brief description of the projectile and high temperature, high-pressure gunpowder gas gun tube barrel bore mechanical, physical, chemical effects, so that the ablation bore wear and tear, ballistic performance decline, eventually leading to the end of the life of the barrel. In recent years, with the improvement of the technical performance of guns and guns and tactics, the ablation of barrel borers is becoming more and more serious. Therefore, higher requirements are put forward for the research on ablation mechanism, ablation reduction technique and corresponding testing technology.
