Abstract
Current weapon system lubricants have performance limitations in extreme climatic conditions, specifically in sand and dust and cold environments. An alternative solid lubricant based lubrication system was investigated and validated using the ASTM subscale tests. The solid lubricants were selected and evaluated based on weapon system lubrication requirements. The solid lubrication systems were evaluated for coefficient of friction, wear, load carrying capacity, endurance (wear) life and corrosion resistance. The novel lubrication system showed superior subscale performance compared to current gun lubricants. It has the potential to provide much better performance than current gun lubricants, especially in sand, cold and humid environments.
