- The purpose of this study was to investigate the wetting characteristics of three different oxide substrates (alumina, magnesia and dolomite) in order to examine the work of adhesion of Fe-Cr alloys on these substrates. The contact angle of a liquid drop (Fe-Cr alloy) on the oxide substrates was investigated at 1823 K under a H-2 atmosphere by the sessile drop technique. The contact angle slightly decreased on the alumina and dolomite substrates with increasing chromium concentration, but did not change as much on the magnesia substrate. Among the tested substrates, alumina exhibited the highest contact angle and dolomite exhibited the lowest one. Accordingly, dolomite had the strongest work of adhesion, which was in agreement with the observations in the practical process.
