EFFECT OF ADDITIONAL ELEMENTS Ni AND Cr ON WETTING CHARACTERISTICS OF LIQUID Cu ON ZIRCONIA CERAMICS

摘要

The effect of additions(Cr, Ni and 80Ni.20Cr)on the wetting characteristics of liquid Cu on ZrO-2 have been studied using a sessile drop method. Analysis of reaction layers at a solidified droplet/ZrO_2 Interface have been performed. Additions of 80Ni.20Cr alloy or Cr alone reduce the contact angle of liquid Cu on ZrO_2. The simultaneous addition of Ni and Cr can markedly improve the wettability of liquid Cu on ZrO_2.
