摘要
Abstract
The iridium coatings were prepared on the surfaces of molybdenum,tungsten and rhenium substrates by electrodeposition in molten salts of chlorides.The microstructures,compositions and phase constituents of the coatings were investigated by scanning electron microscopy（SEM） and energy-dispersive X-ray spectrometry（EDX）.Characteristics of molybdenum,tungsten and rhenium substrates during electrodeposition were studied.The results indicated that molybdenum and tungsten were severely corroded in molten salts of chlorides,interlayers composed of chlorides and corrosion products were formed after electrodeposition,which greatly reduced the binding force between the coating and substrate,and the iridium coatings fractured easily.However,rhenium has a good stabilization in chlorides.No corrosion was found during electrodeposition,there is no interlayer formed,and the iridium coating and rhenium substrate immediately combined,a dense and smooth iridium coating was obtained on the rhenium substrate.关键词
