| 摘 要： | 探讨了以手工方式进行铸造钴铬合金口腔修复材料微束等离子电弧焊的可行性，试验过程电弧燃烧稳定，焊接接头充分熔透，母材与焊接连接良好，未见气孔，裂纹等缺陷。显微组织显示：焊缝与母材均为铸态的树枝状晶粒，几乎无焊接热影响区，焊接接头的电子能谱成分扫描、机械性能、显微硬度测试显示，接头成分均匀，焊缝与母材强度相当，微束等离子焊在口腔修复领域的应用前景明显优于其他熔化焊接方法。

| Abstract: | The article discussed the technology of micro-plasma arc manual welding for oral cavity repair material of molten Co-Cr alloy.The tests show:there are steady arc burning,fully fused weld joints,good connection between base metal and weld joint ,no air bubble,cracks etc.Microstructure show s:there are molten arborescent structure joints,few heat infection zone,the mechanism performance and microhardness show:the components of joints are even,and the base and weld are even in the strength.It is considered that micro-plasma arc welding has a good application in the field of oral cavity repair. |
