Abstract: 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.Key
