Abstract

OBJECTIVE: This study aimed to determine the effect of recasting in vacuum with argon on the chemical composition of cobalt-chromium (Co-Cr), commercially pure titanium (cpTi), palladium-based (Pd-based), and aurum-platinum (Au-
Pt) ceramic alloys.

METHODS

Without adding new alloys, Co-Cr, cpTi, Pd-based, and Au-Pt ceramic alloys were recast one to three times under the condition of vacuum compressive casting with argon. Before recasting, four previously cast ceramic alloys were treated with the corresponding method. After polishing, the chemical composition of the four ceramic alloys recasted one to three times were determined by energy-dispersive spectrometry.

RESULTS

No significant difference was observed in the chemical composition of the four ceramic alloys recast 1-3 times (P>0.05).

CONCLUSIONS

Under the condition of vacuum with argon, the recasting had no obvious influence on the chemical composition of Co-Cr, cpTi, Pd-based, and Au-Pt ceramic alloys.

摘要

目的

本研究旨在确定在真空环境下用氩气重熔对钴铬（Co-Cr）、商业纯钛（cpTi）、钯基（Pd基）和金铂（Au-Pt）烤瓷合金化学成分的影响。

方法

在不添加新合金的情况下，将Co-Cr、cpTi、Pd基和Au-Pt烤瓷合金在真空氩气压缩铸造条件下重熔1至3次。重熔前，对四种预先铸造的烤瓷合金采用相应方法进行处理。抛光后，用能谱仪测定重熔1至3次的四种烤瓷合金的化学成分。

结果

重熔1至3次的四种烤瓷合金的化学成分未观察到显著差异（P>0.05）。

结论

在真空氩气条件下，重熔对Co-Cr、cpTi、Pd基和Au-Pt烤瓷合金的化学成分无明显影响。
