本文通过对某大口径枪管采用激光强化后,其显微组织结构发生的变化和在寿命试验中的数据进行分析,从内到外、从理论到实践地对激光强化这一特种技术如何能有效提高枪管内膛疲劳强度,从而能延长枪管寿命的原因进行了深入探讨,并对枪管内壁激光强化良好的工艺性进行了较为全面的阐述。 In this paper, a large-caliber barrels using laser enhanced microstructure changes and life-long test data analysis, from the inside out, from theory to practice on the laser enhancement of this special technology can be Effectively improve the fatigue strength of the barrel bore, which can extend the life of the barrel of the cause of in-depth discussion, and the barrel of the laser enhanced good process of a more comprehensive exposition.
