Abstract

The effect of additions (Cr, Ni and 80Ni·20Cr) on the wetting characteristics of liquid Cu on ZrO₂ have been studied using a sessile drop method. Analysis of reaction layers at a solidified droplet/ZrO₂ interface have been performed. Additions of 80Ni·20Cr alloy or Cr alone reduce the contact angle of liquid Cu on ZrO₂. The simultaneous addition of Ni and Cr can markedly improve the wettability of liquid Cu on ZrO₂. According to SEM and EPMA observations, dissolution of the additions into liquid Cu droplets occurred. A uniform distribution of Ni throughout the Cu droplet and segregation of Cr at the Cu droplet/ZrO₂ interface were observed in solidified specimens.
