目的研究激光焊接对烤瓷合金金瓷结合性能的影响。方法将10个激光焊接的CW-PA烤瓷合金试棒在焊缝熔区烤上瓷盘，做棒盘实验，测量金瓷结合强度,并做扫描电镜观察和X衍射能谱分析。另10个未焊接的CW-PA烤瓷合金试棒的棒盘实验作对照。结果焊接试件的金瓷结合强度为41.32±6.69 MPa, 接近未焊试件的金瓷结合强度(45.71±9.98 MPa，P＞0.05)。金瓷界面微观形貌表明金瓷两相的紧密结合，熔区主要元素成份及比例基本没有改变。结论激光焊接不影响金瓷结合。

Objective　This study was aimed to investigate the bonding effect of laser welding on ceramic fused to metal.Methods　Ten laser welded CW-PA ceramo-alloy rods were fused with porcelain at fusion zone. The porcelain-metal bond strength was measured with pull-through test. SEM examination and EDAX analysis were performed. Ten non-welded CW-PA ceramo-alloy pull-rod plates were used as comparison. Results　The results showed that the bond strength of laser welded sample was 41.32±6.69 MPa, approaching to 45.71±9.98 MPa of the non-welded sample (P＞0.05). The microscope displayed the interface compacted union of the two phase boundary. There was no change in the elements and their ratio at the fusion zone. Conclusion　These results indicate that laser welding does not affect ceramic fused to metal.
