Abstract
Known methods of melting Titanium and its alloys for the purpose of sheathing a ceramic filament include the premelting of the metal in a crucible. This method results in contamination of the metal. The present invention obviates the crucible and instead positions a rod of solid Titanium or an alloy thereof adjacent the filament and locally heats the end of the rod. The melt continuously coats the filament which is then traversed laterally of the rod. The method is employed in an inert atmosphere and contamination is thus avoided. In a preferred embodiment, a computer controls the rate of melting of the rod, the movement of the rod, and the lateral movement of the filament.
