| Abstract: | Stellite coatings were deposited on stainless steel 2Crl3 by DC magnetron sputtering and then were melted by electron beam. Corrosion resistances in 0.5M H2SQ4 and 0.1M NaCl solution were investigated by means of electrochemical technique. It was found that corrosion resistance was greatly improved by this treatme t. The critcal current I, and passivation current Im were reduced by one and two order of magnitude, respectively. Analyses of micrograph and chemical compoesition in surface coating were carried out by SEM-EDAX |
