Microstructure Analysis of Al2O3 Ceramic Coatings Composite Steel Plate Prepared by Self-Propagating High-Temperature Synthesis
Abstract:
This manuscript was used to test feasibility that the Al2O3 ceramic composite steel plate was fabricated by Self-propagating High-temperature Synthesis (SHS).The Al2O3 ceramic coatings were prepared on the steel plates.The ceramic coatings had been subsequently characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) attachment. The results showed that the ceramic coatings could be divided into three layers called Al2O3 ceramic layer, Fe/Al2O3 blending layer and iron layer from the roof to the bottom. Al2O3 ceramic layer had many porosities and low density. The tissue structure of Fe/Al2O3 blending layer was compact and had no porosities.
