Al-Cr COATINGS PREPARED BY DIFFUSION AT LOW TEMPERATURE AND ITS PHASE CHARACTERIZATION
Al-Cr涂层低温扩散制备及其相组成的研究

The Al-Cr coating exhibits a good steam oxidation resistance and can act as tritium permeation barrier.It is necessary to prepare Al-Cr coating at low temperatures to avoid detrimental effect on the mechanical properties of the substrate.In the present study,a new process was proposed to prepare Al-Cr coating by electrodeposition of Cr/Al composite coatings firstly,and then heat treatment at low temperatures.The Cr/Al composite coatings were obtained by electrodepositing Cr from aqueous solution followed by...
