Interfacial Energetics in Metal-Metal, Metal-Ceramic, Metal-Semiconductor, and Related Solid-Solid and Liquid-Solid Systems
Several years ago when some of the topics to be discussed were first presented; it was pointed out that there had been very few measurements of the so-called work of adhesion or adhesive energy in any practical, technologically important systems, and almost no attempts to measure this property over a range of temperatures for specific metal-ceramic or related systems (Murr, 1978). The same is still true even though films and coatings, composites, complex laminates, and similar solid-solid and even solid-liquid systems are becoming increasingly and technologically more important; viz. electronics, solar materials applications, etc. Measurement of the work of adhesion can also provide some basis for understanding the macroscopic changes in friction and wear properties, e. g. the Co-cemented WC hard composites (Hartley, 1979).
