ABSTRACT


This study showed the capability of the Uniform Droplet Spray (UDS) process to produce uniform droplets of high melting point copper-tin alloys. An apparatus was designed, fabricated, and utilized to produce uniform powders of bronze.

Unlike conventional manufacturing techniques such as spray forming, the UDS process produces droplets of uniform diameters with variances of 3 to 4%. Uniform Cu-20%Sn droplets were produced from 100 5m and 175 5m diameter orifices.

Although uniform bronze droplets were produced, the modified system is not as consistently robust as it should be, and recommendations are made to solve this problem.
