镁搪瓷的研究

<正> The method for preparing the enamel to be coated on magnesium alloy has been described. It is believed that the main factors effecting on adherence of magnesium enamel are substrate, surface treatment, enamel composition, and enamel drying and firing time. The enamel magnesium alloy with good adherence and bending angle of θ≈80° has been obtained in the experiment, during which low melting lead enamel was applied to the surface of magenesium alloy pretreated with water glass. On the other hand, adherence became poor and surface appeared black when the lead enamel was applied to the surface of magnesium alloy pretreated with the Dm method. The black surface resulted from lead which had been reduced by Mg and released from the interface between enamel and magnesium a loy, exerting a bad effect on adherence.The experiment has also shown that neither phosphate enamel nor antimony enamel resulted in good adherence when they were applied to the magnesium alloy.
