Study on Preparation and Properties of Al₂O₃-Fe Based Metal Ceramics

Abstract:

Al₂O₃-Fe based metal ceramic is a functional ceramic material prepared by high temperature sintering with Al₂O₃ as the main component, plus iron powder (binder phase) and other additives. In this paper, the composition design of Al₂O₃-Fe based metal ceramic was made, and the performance of the material was tested and studied. The change of the content of iron powder also has a great influence on the compressive strength and bending strength of the Al₂O₃ metal ceramic. Experiments also show that the Al₂O₃-Fe-based cermet has good corrosion resistance. Finally, the following conclusions were obtained through the comprehensive analysis: the best test formula is No.4 sample, and its compressive strength is 79.79MPa, bending strength is 15.90 MPa, corrosion resistance rate is 0.028 g/dm²·h.
