Thermochemical erosion of propellant with nanometer additives

The bore-wear reducing additives are usually used in the gun propellant for reducing the wear or erosion of gun barrel because of its evident effects and simple technique. Though nanometer materials have many distinctive features, the problem of how to use nanometer materials as the bore-wear or bore-erosion reducing additives in guns has not been investigated deeply. For solving the problem, some experiments were conducted. The erosion data of both propellant with nanometer additives and standard propellant were obtained by a semi-closed bomb. The experimental result shows that nanometer additives play a role in reducing erosion to a certain degree. SEM pictures show that the nanometer additives have no influence on formed quality of the grains.
