The interface between a polycarboxylate cement and a high copper amalgam core containing (21%) tin by weight was analyzed by EDX. It was found that, the tin concentration at the interface was very low (1.26%). On the other hand, a higher copper concentration was demonstrated (6.39%). Mean while a correlation was established between the tin concentration of the amalgam core and the shear bond strength with polycarboxylate cement. Moreover, it could be assumed that, the tin concentration rather than the copper concentration of the amalgam cores has the substantial effect on the shear bond strength between amalgam cores and polycarboxylate cement.
通过能谱仪（EDX）分析了聚羧酸锌水门汀与含21%（重量）锡的高铜汞合金核之间的界面。结果发现，界面处的锡浓度非常低（1.26%）。另一方面，显示出较高的铜浓度（6.39%）。同时，在汞合金核的锡浓度与聚羧酸锌水门汀的剪切粘结强度之间建立了相关性。此外，可以假定，汞合金核的锡浓度而非铜浓度对汞合金核与聚羧酸锌水门汀之间的剪切粘结强度有实质性影响。
