【摘要】 采用实况采相观察了Ｃｏ－Ｃｒ３Ｃ２合金与ＷＣ的润湿现象，采用ＪＣＸＡ－７３３型电子探针显微分析仪和３０１４型Ｘ射线衍射仪研究了Ｃｏ－Ｃｒ３Ｃ２合金熔渗ＷＣ所形成的组织，为ＷＣ－Ｃｏ合金中添加Ｃｒ３Ｃ２的作用机理提供解释依据。更多还原

【Abstract】 The phenomena of wettubility of Co-Cr3C2 alloy with WC have been observed by adopting on-the-spot video recording and the structure formed by the infiltration of Co-Cr2C3 alloy into WC has been studied by adopting JCXA 733 type electronic probe microanalyser and 3014 type X-ray diffractometer to provide basis for the mechanism of the role of addition of Cr3C2 into WC-Co alloy.更多还原
