Processing of Iridium and Iridium Alloys

Iridium and its alloys have been considered to be difficult to fabricate due to their high melting temperatures, limited ductility, sensitivity to impurity content and particular chemical properties. The variety of processing methods used for iridium and its alloys are reviewed, including purification, melting, forming, joining and powder metallurgy techniques. Also included are coating and forming by the methods of electroplating, chemical and physical vapour deposition and melt particle deposition.
