KM is a low temperature deposition process that employs a specially designed, two-phase, friction compensated sonic nozzle to accelerate micron-size powder particles entrained in a helium carrier gas. The sonic nozzle directs the gas/particle suspension at a temperature well below the powder's melting point onto a substrate. The high speed collision (700-1000m/s) of the micron-size powder particles cause very large strain and strain rates in the particles, which produces depositions having unique strain-hardened properties resulting from plastic deformation.
