ABSTRACT:
The average diameter of atomized droplets is reduced thereby reducing both the frequency of collisions between droplets as well as the turbulence at the liquid/solid interface. Reducing the porosity of a spray cast deposit leads to improvements in both the ductility and the electrical conductivity of the deposit.
