The surface tension and the wettability of molten metal-ceramic system, which are the indispensable parameters in considering molten metal infiltration into pores of ceramics, have been studied by the use of the sessile drop method. Manganese and zirconia ceramics containing yttoria were prepared as the metal and the ceramic, respectively.
The surface tension of molten manganese was approximately 1.1 N/m at 1573∼1773 K. The contact angle was in the range of 74°∼86°, suggesting that this metal-ceramic system had a good wettability. Manganese diffused into zirconia matrix. Estimating the bond strength at interface, it was presumed that not only intermolecular force but also chemical interaction force contributed to the interfacial bond.
