摘要:

目的 研究真空加氩气环境中反复熔铸对4种常用非镍基烤瓷合金(钴铬、纯钛、钯基和金铂烤瓷合金)化学成分的影响。方法 真空加氩气保护环境下反复熔铸钴铬、纯钛、钯基和金铂烤瓷合金1~3次,每次再熔铸前对废旧合金均经过相应的再熔铸前处理,打磨抛光后,采用能谱仪检测4种烤瓷合金1~3次熔铸后的化学成分。结果 4种合金反复熔铸1~3次的化学成分含量变化均无统计学差异(P>0.05)。结论 真空加氩气环境中反复熔铸对钴铬、纯钛、钯基和金铂烤瓷合金的化学成分无明显影响。

Abstract:

Objective This study aimed to determine the effect of recasting in vacuum with argon on the chemical compo-sition 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).Conclusion 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.
