Wetting of Hot Metal Filaments by Molten Metals

In making thin films of metal by evaporation it is often convenient to evaporate the metal from an incandescent metal filament. In order that evaporation may take place properly the molten metal being evaporated must wet the incandescent filament. The work previously reported on the wetting of metal filaments by molten metals has been extended to include tantalum as a filament material. This report brings the work up to date. It includes the following metals as filament materials: nickel, platinum, molybdenum, tantalum, and tungsten. The following metals were evaporated from the molten state: aluminum, silver, gold, copper, nickel, chromium, and platinum
