STUDY OF STRUCTURE OF DACROTIZED COATING
锌铬膜层结构的研究

The composition and structure of dacrotized coating were studied by SEM, XPS,XRD,DTA,etc. The mechanism of producing dacrotized coating is proposed. Result showed zinc in the coating exists as zinc powder, zinc powder was wrapped in zinc oxide and the space between zinc powders and between zinc powders and metrix was filled by trivalence chromium oxide.
