Nonequilibrium Wetting in Si/Al-Si and Ni/Al-Ni Systems

Abstract

Wetting phenomena have been investigated for a long time. The investigation of the wetting phenomena originated from the field of adhesion and waterproof treatment, but the chemical reaction or the mass transfer between liquid and solid have not been considered. In this paper, the influence of the reaction and the mass transfer on wetting were studied.
During the contact angle measurement of metal/metal and ceramics/metal systems at high temperature, we have to take care with interfacial reactions and mass transfer at the interface. The influence of the interfacial reactions and the mass transfer is microscopically inspected on the interface between solid and liquid after the contact angle measurement.
