Abstract

A ceramic layer was produced on a steel pipe inner surface by a centrifugal thermite process. A powdery mixture of ferric oxide and aluminum was used with the glass whose major compositions were SiO₂, Na₂O, CaO, and MgO. The ceramic layer consisted of the crystalline structures of corundum (a-Al₂O₃) and hercynite (FeAl₂O₄). The amorphous phases of Ca₃Al₂(SiO₄) ₃, MgFeAlO₄ and NaAlSiO₄ in the ceramic layer were found to be responsible for a significant improvement of the dense structure. The glass addition increased the density of the ceramic layer from 2.9 g/cm³ to 3.6 g/cm³ and the hardness from 1,450 to 1,800 Hv.
