Corrosion Analysis of Damage Resistant Materials used in Military Armoured Vehicles in Poisonous Gas Environment

With the improvement of China’s military strength, military armoured vehicles are very effective in dealing with various harsh environments. The poisonous gas environment is very serious against the body of the military armoured vehicle. For this reason, the damage-resistant material for the car needs to be developed, and the corrosion resistance of the material is analysed. Metal and polymer damage resistant materials are selected as research objects. In the three environments of alkaline poison gas, industrial poison gas and acid gas, the outdoor exposure test is carried out, and the indoor accelerated test under the combined environmental factors is implemented to obtain the mechanism of corrosion and aging behaviour of the typical material of the vehicle. Experiments show that the damage resistant material can effectively enhances the corrosion resistance of the car body in a poisonous gas environment.
