摘要：
Effects of interlayer composition on bonding strength and interfacial microstructure of green joined Al2O3-ZrO2 ceramics were studied in this paper. Green bodies of Al2O3 and ZrO2 ceramics were joined by using interlayer composed of Al2O3-Al-SiO2 system at 1550 degrees C for 2 h without applied pressure. The effect of Al on the bond strength and microstructure of the joints were investigated. Through comparing five approaches or conditions, the results indicate that when adding 22% Al, the joints are the best in terms of bend strength and the microstructures of the joints are homogeneous and without obvious cracks, pores and defects.
