Army Team Tests Cold Spray Repair on Bradley Turret Gun

Jeff Brody

Engineers and scientists from multiple U.S. Army groups have teamed to develop a cold spray technology for repairs on the M2 Bradley Fighting Vehicle’s turret gun mount. The team consisted of personnel from Army Research Laboratory, Ground Vehicle Systems Center, Armaments Center, Bradley Product Manager and Red River Army Depot, the service branch said Wednesday.

“This project demonstrated the ability to apply new manufacturing technologies to bring components back into service that would otherwise be scrapped during depot maintenance operations,” said Gehn Ferguson, ARL materials engineer at Army Combat Capabilities Development Command.

The cold spray process uses accelerated micron-sized particles to fill gaps on damaged surfaces. A repair using cold spray would cost only $1,000, compared to the $25,000 cost of a gun mount replacement.

ARL chose Bradley’s turret gun as a cold spray subject due to the laboratory’s experience with similar metals. Four to five more gun mounts will undergo cold spray repair over the next six months.  The Army’s Manufacturing Technology Program funded the project.

Rich Ryan, director for international programs, nuclear forensics, resiliency and survivability in the office of the deputy assistant secretary of defense for nuclear matters, said the U.S. military has opened a cloud-based library to support the protection of microelectronics used in nuclear systems. The Department of Defense handles strategic deterrence through its nuclear triad and space systems, whose electronic components can be vulnerable to ionized radiation, electromagnetic pulse and other threatening types of stimulus.
