Abstract
In view of the serious erosion problem of the gun barrel with the R2 high-energy propellant, an erosion tube device method was adopted, and silane organic substances, silicate inorganic substances, titanium dioxide nanoparticles and paraffin wax were selected as erosion-reducing additives. The effect of different erosion-reducing additives on the erosive property of R2 propellant was investigated by means of external addition. The erosion inhibition principle was also briefly investigated by scanning electron microscope and energy dispersive X-ray spectroscopy. The results show that paraffin wax has excellent ability to improve gun barrel erosion resistance, the erosion-reducing efficiency can reach up to 31.2%, the erosion-reducing efficiency of silanes is the next most effective, and silicate is poor.
