AbstractThe effect of element Ti on adherence between a CoO-bearing single-layer enamel coating and steel was investigated. Falling-weights tests were carried out and cross-sections at interface of the enamel/substrate were analyzed with a scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS). Results show that addition of TiO2 reduced adherence of the enamel coating by hindering the formation of anchor-like alloy precipitates. The decrease of anchor points lies in the following three reasons: I. The diffusion path of Co2+ ions to the interface was lengthened because of the blocking effect of rutile and the FeTiO3 crystals; II. Formation of CoTiO3 crystals leads to a reduction of free Co2+ ions; III. Co-Fe precipitates form away from the enamel/substrate interface, as FeTiO3 crystals provide extra surface for the nucleation of Fe-Co alloy precipitates.
