小口径速射武器在发射过程中,由于火药爆炸气体及高速运动弹丸的作用,使枪膛(或炮膛下同)表面产生严重的烧蚀、冲刷及磨损,从而引起武器的失效。 实践表明,除去正确选用身管材料,合理确定冷、热加工工艺之外,采用表面防护方法,在枪膛表面上,涂覆一层耐磨、耐蚀涂层,是提高武器使用寿命的一条重要途 Small-caliber rapid-fire weapons in the firing process, due to the explosive powder gunpowder and high-speed movement of the projectile, the barrel (or the same below) the surface ablation, erosion and wear and tear, causing the failure of weapons. Practice shows that, in addition to the correct selection of barrel material, a reasonable determination of cold and hot processing techniques, the use of surface protection methods, the surface of the chamber, coated with a layer of wear-resistant, corrosion-resistant coating is to improve the life of a weapon Important way
