Iridium and its alloys play an important role in the field of high temperature applications due to their high melting temperature,excellent corrosion resistance and oxidation resistance at high temperature. However,iridium has been considered to be one of the metals which are most difficult to be fabricated,which confines its applications. The variety of processing methods used for iridium and its alloys are reviewed in the present paper,including the purification,melting,powder metallurgy,deformation and deposition processing. Emphases are placed on the deposition processing methods of iridium coatings,including electrodeposition in molten salts,CVD,PVD,and then these methods are evaluated respectively. Applications of iridium and its alloys are also refered to briefly.
