Tungsten is a heavy metal that can be classified as a refractory metal, i.e., one with a high melting point. Refractory metals can be useful for their strength at high temperatures and their...
Refractory metals are characterized by their extremely high melting points, which range well above those of iron, cobalt, and nickel. They are used in demanding applications requiring high-temperature...
Often called TIG welding (Tungsten Inert Gas), this welding process joins metals by heating them with a tungsten electrode which should not become part of the completed weld. Filler metal is sometimes...
Tests on PVD chambers show that an aluminum twin-wire-arc spray coating effectively reduces the flaking of refractory metals from chamber shields and helps control particle generation. Escalating...
Refractory and reactive metals include boron (B), tungsten (W), tantalum (Ta), molybdenum (Mo), niobium (Nb) / columbium (Cb), zirconium (Zr), hafnium (Hf), thorium (Th), vanadium (V), chromium (Cr),...
