[Effects of laser welding on ceramic fused to metal]
1Department of Prosthodontics, School of Stomatology, WCUMS, Chengdu 610041, China.
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.
