Cu-Co/Ni合金对渗钨石墨的润湿性研究

Research on the Wettability of W-coated Graphite By Cu-Co/Ni Alloys

本文首先在 １． ３３ × １０－３Ｐａ真空下对石墨表面进行了渗钨处理，并在石墨表面生成 了一层Ｗ＋Ｗ２Ｃ＋ＷＣ 表面膜．然后，用座滴法于１．３３×１０－４Ｐａ真空下测定了Ｃｕ－ Ｃｏ／Ｎｉ合金对不同条件下渗钨石墨的润湿角。实验发现，渗钨处理可以大大改善Ｃｕ－ Ｃｏ／Ｎｉ合金对渗钨石墨表面的润湿性。

The W-coating treatment of graphite was carried out under 1.33x10-3Pa vacuum at first and a thin film Of WC+W2C+W was formed on the treated graphite surface. The contact angles of Cu-Co/Ni alloys on the W-coated graphite were then measured using the Sessile-Drop technique. It was found that the W-coating treatment of graphite can improve the wettability of graphite by Cu-Co/Ni alloys markedly.
