Abstract
A rotary liquid metal atomizer is positioned to receive a stream of molten metal on the top thereof. The atomizer is formed as a hollow disc means having a concave top surface and mounted for rotation at high R. P. M.'s on the top of a hollow drive shaft. A circular coolant baffle is located in the hollow disc means, for cooling fluid to flow around, and is mounted on the top of an inlet cooling tube located within the drive shaft. Cooling fluid is directed through the inlet cooling tube to the top of the water baffle where it flows through a hole in the center thereof and around the space between the baffle and the interior of the hollow disc means and down between the inlet cooling tube and drive shaft. The top of the disc means over the coolant baffle is formed of copper. A metal rim is placed around the upper outer periphery of the copper disc forming a recessed center portion. A ceramic coating is placed in the recessed portion with its outer edge against the inside of the rim. The metal rim acts to hold the coating against centrifugal force and to provide a material for the liquid metal to melt and form a fusion weld therewith to firmly attach a controlled solidified metal skull to the atomizer.
