Thermally Stable Machine Gun Barrel

The overall objective of the proposal is to develop and demonstrate a recently developed metal treatment and combine it with alternative barrel designs. Dark Metal Technology (DMT) is a unique technology that provides a highly wear resistant and self-lubricious surface for finished steel parts in military weapons. DMT improves the performance of machine gun barrel steel by providing: • Outstanding wear resistance, high lubricity, and anti-galling without increasing hardness for both low and high grade carbon steel alloys used in machine gun components. • Maintain dimensionally stable parts, whose surface tolerances are unaffected, because there is no build up on surfaces from diffusion treatments. • A process that can be used both on new parts and field service parts as well.
