In this research, the metal and ceramic laminates Ti/Al2O3, Ni/Al2O3 were prepared by PAS. The bonding interfaces of Ti/Al2O3, Ni/Al2O3 were observed and analyzed. The microstructures of laminates were observed by SEM. It was shown that the joints of the samples were tight and had not visible flaws. Moreover, the comparison of Ti/Al2O3 and Ni/Al2O3 laminates showed that the join mechanisms of them were different. Ni/Al2O3 laminates that had not apparent conversion zone were joined by diffusion and had lower bond strength. Ti/Al2O3 laminates have obvious conversion zone because Ti and oxygen have strong combining power. Three-point bending test indicated that the fracture of laminates was correlated to the bond strength of the interface.
