The U.S. Army has declared that with funding from the Military’s Manufacturing Technology Program, a crew of engineers and scientists from the U.S. Military Combat Capabilities Development Command Army Research Laboratory and the Armaments Center worked collectively to develop a cold spray process to restore costly blister gun mounts on the Military’s M2 Bradley Fighting Vehicle.
The project started in 2017 when CCDC ARL visited RRAD to view the reviewing process and access the wear on the Bradley turret gun mounts. RRAD, the first depot responsible for the Bradley vehicle, examines gun mounts for extreme damage. In upcoming months, CCDC ARL developed and demonstrated a process for improving the gun mounts utilizing cold spray. Before growing the cold spray procedure, worn gun mounts that were scrutinized and recognized as non-repairable were disposed of.
While the price of a brand new 25mm gun mount is over $25,000, a cold spray fixture prices approximately $1,000. Moreover, the cold spray process improves zeal by reducing the time that a Bradley is out of service while decreasing the burden on the supply chain by reducing the need for stockpiling new gun mounts.
Cold spray is a course where micron-sized particles are stimulated in a high-velocity gas stream through a nozzle and subsequently connected on a target surface. The accelerated particles impact and bond to the floor, leading to a buildup of the sprayed materials. Each sprayed particle and the target surface stay solid in the course.
While the venture initially started as a way to fix gun mounts, the material used in the cold spray process is much more sturdy, which implies it may even be used to increase the life of new gun mounts.
