自修复技术对减轻身管内膛烧蚀磨损的研究

Study on Alleviating the Rubbing Abrasion and Erosion on the Barrel Bore with Self-repairing Technology

通过对火炮身管内膛表面进行检测,认为微裂纹是导致火炮身管烧蚀磨损的重要原因。提出运用纳米技术修复火炮身管内膛的方法,并模拟火炮发射工况进行模拟实验。结果表明,该技术可利用基体工作时的高温高压环境,有效修复基体表面微裂纹。

By detecting the surface of canal, the microcrack was considered as the vital reason which causes the nabbing abrasion and erosion on the barrel bore. The method using the nanometer technology to repair canal was put forward, and simulation experiment was carried out to test it. The results show that microcracks can be repaired efficently on the condition of high-temperature and pressure.
