Abstract In this present paper,the operation technology for preparation of aluminium-chromium alloy coating by electron beam evaporation pla ting was studied.Corrosion resistance of the coatings was investigated,meanwhile the phase,morphology and the effect of heat treatment on the diffusion between the Al-Cr coating and the matrix were discussed.The analysis of ingredients of t he coating and the target shows that the chromium contents of the coating are ve ry different from that of the target.It is proved that Al-Cr alloy coating of th e chromium contents of 1.5%～5% can be regarded as the anodic coatings for norma l steel matrix,which accordingly has good electrochemical protection function i n 283K,30 g/L NaCl solution.The major phases of the coating are Al and a small q uality of Cr9Al17.Cr9Al17 in the coating increases with the Cr c ontent of the target.The deposited coating takes on the orientation.After 600℃, 1 h heat treatment,ingredients of the coating and matrix diffuse each other.
