초록
The inner surface of a steel pipe could be lined with ceramics by means of a SHS reaction under centrifugal force. Some physical characteristics of the ceramic layer were investigated with the change of filling ratio (thermit mixture, Fe2O3 and Al) and the addition of silica. Two compositions, -Al2O3 and FeAl2O4, were detected in the dispersed phase. The size of alumina grains became larger towards the pipe innermost side at high mixture filling ratios. Additionally, it was found that amorphous silicate materials formed by the addition of silica makes the layer dense significantly. The apparent density and hardness of the ceramic layer were improved from 2.9 g/cm3 and 1,430 Hv to 3.7 g/cm3 and 1,700 Hv with the effect of additive, silica.
