Abstract

The results of this study suggest that the strengthening of aluminous porcelain with Sn-plated Pt is an effect of (1) a chemical interaction involving diffusion and dissolution of Sn-oxide in the glass phase of the porcelain and (2) a better wetting of te Sn-plated substrate by the porcelain. This conclusion supports and confirms the earlier hypothesis of McLean and Sced.

摘要

本研究结果表明，用镀锡铂强化氧化铝瓷是以下两种作用的结果：（1）一种涉及氧化锡在瓷玻璃相中的扩散和溶解的化学相互作用；（2）瓷对镀锡基体的更好润湿性。这一结论支持并证实了麦克林和斯凯德早期的假设。
