The objective in this research is to gain a fundamental understanding of the wetting and adhesion of aluminum alloys to SiC. The preliminary approach has been to study the infiltration kinetics of molten aluminum alloys into green silicon carbide compacts and relate the results to the interfacial bond strength. Since both infiltration rate and interfacial bond strength are related to the interfacial tension at the interface, our approach has been to isolote those parameters which affect both infiltration kinetics i.e. viscosity, density, and pre size and interfacial bond strengthi.e. enthalpies of solution and electronic contributions and then to correlate the kinetics and bond strength to the most fundamental parameters.
