| 摘 要： | 用金相显微镜，X射线衍射(XRD)，扫描电镜(SEM)，透射电镜(TEM)和X射线能谱(EDS)对等离子弧堆焊Co—Cr—W系多元合金层进行了研究，结果表明，合金层基体为具有(200)晶面择优取向的Co基固溶体，Co基固溶体中存在许多堆垛层错；与固溶体组成共晶体的碳化物主要为具有六方点阵并含有层片状孪晶的(Cr,Fe)7C3。

| Abstract: | The microstructure of Co-Cr-W alloy plasma surfacing has been investigated using metallurgical phase, X-ray diffraction, SEM and TEM. The results indicated that the alloy layer was composed of Co base solid solution with the preferred direction at (200) crystal plane and (Cr, Fe)7(C, B)3. The TEM research showed that there was a lot of stacking fault ribbons lying in Co-base solid solution. The result also showed that (Cr, Fe)7(C, B)3 was hexagonal lattice with lamellar and flake twin. |
