延寿修复材料在身管武器上的应用研究

为了研究延寿修复材料对武器身管的修复延寿效果,开展了延寿修复材料的应用研究。通过扫描电子显微镜、透射电子显微镜、能谱仪、烧蚀试验机、摩擦磨损试验机等对延寿修复材料的形貌、相结构、烧蚀性能、腐蚀性能、摩擦磨损性能进行了表征;并利用某型枪、某型滑膛炮进行了实弹射击试验。研究结果表明:修复后,在金属表面附着一层涂层材料,枪管及炮管表面的凹坑、裂纹逐渐被填补,表面渐趋光滑;修复材料使用后能够明显降低枪管温升,且不会对枪的精度产生影响;对于中小口径火炮,修复材料可在一定范围内增大弹丸初速,减小膛径磨损量。

Applied Research on the Life Prolonged and Restored Materials in Gun Tube Weapon

In order to study the effect of life prolonged and restored materials on gun barrel,the life prolonged and restored materials are studied.The morphology,phase structure,ablative resistance,corrosion resistance,friction and wear properties of the life prolonged and restored materials are characterized by scanning electron microscope (SEM),transmission electron microscope (TEM),energy disperse spectroscope(EDS),ablation test machine and friction wear test machine.The firing tests of gun and smoothbore cannon made of the life prolonged and restored materials were completed.The results show that a layer of coating material is attached to the metal surface after restoring.The barrel surface is filled with pits and cracks,and the surface is smoothed.The restored material can significantly reduce the barrel temperature,which will not affect the accuracy of the gun.For the small caliber gun,the restored material can not only increase the initial velocity,but also reduce the wear of gun barrel.
