Interfacial Adhesion Properties of Enamel-coated Alloyed Steels

The interfacial adhesion properties of enamel-coated, alloyed steels were in detail characterized by spectroscopic techniques. The surfaces of alloyed steels existed as oxidized states of Fe(3)O(4). Therefore, the oxidized sui-faces of the steels significantly interacted with the coated enamels for the adhesion. Ti-alloyed steel showed many micro-boundaries during thermal treatment and these micro-boundaries might cause the decline of the interfacial adhesion between enamel and steel. The depth profiles of enamel-coated, alloyed steels were investigated by GDS (glow discharge spectroscopy) and Ti component was found to be related to the interfacial adhesion between enamel and steel.
