摘要
为分析某型号机枪枪管的延寿机理,对4种不同工艺制备的镀铬枪管进行了寿命射击实验。通过解剖失效枪管,发现镀层下基体的初始烧蚀行为存在界面烧蚀、次界面烧蚀和穿透性烧蚀3种典型方式,枪管寿命相应由低到高。
In order to reveal the relation between the fabrication process and erosion life of chromium plated gun barrel used in model products, the eroded gun barrel with four different fabrication processes have been examined. It has been found that three different erosion modes, i. e. interface erosion, sub-interface erosion and penetrating erosion correspond to the low, medium and high erosion life, respectively.
