Abstract：

We　study　the　oxidation　of　SiO2-Al2O3-CaO-BaO-MgO　based　enamel　coated　Ni　based　superalloy　at　900°C　and　find　that　the　enamel　coatings　are　highly　capable　of　protecting　the　Ni　based　superalloy　from　oxidation.　During　the　oxidation,　the　complicated　composition　crystals　precipitated　in　enamel　lead　to　two　linear　variation　stages　of　oxidation　weight　gain.　Moreover,　the　increased　roughness　of　the　superalloy　interface　due　to　oxidative　attack　and　the　immersion　of　the　enamel　coating　in　superalloy　should　increase　the　interface　bonding　strength.　Finally,　oxidations　of　Al,　Ti　and　Cr　from　superalloy　dominates　the　interfacial　reactions.　©　2020　Elsevier　Ltd
