Many techniques exist to measure the surface energy between aliquid and a liquid or a liquid and a gas (see e.g. the wikipage).
Methods to measure the surface energy between a solid and afluid are rare, but still there is a method developed by Zisman(see e.g. here) that allows you to at least estimate it byextrapolation for solid/gas or solid/liquid, depending on theenvironment that you use in your experiment
What I wonder: is there a method to measure the surface energybetween two non-elastic solids?
One option I could think of is that you could melt one of thesolids and then use the technique of Zisman, but this will limityour knowledge to high temperature surface energy, whereas the onesat low temperature are the thing you are typically interestedin.
