Abstract:

One of the important mechanisms by which a filter can remove particles from a melt is its surface adsorption effect. A thermo-dynamical criterion is presented on which particles are adsorbed spontaneously, according to the relative interfacial energies. Factors which affect the driving force of particle adsorption are discussed. The driving force of particle removal in the filtration of a superalloy is estimated.

Key words: superalloy, filtration, interface
