Pd-C高温共晶点复现技术研究

Study on Recurrence Technology for Pd-C High Temperature Eutectic Point

设计了Pd-C高温共晶点复现装置,包括复现用高温均热炉炉体、温度控制系统、真空泵、充气保护装置、水冷系统、复现用的石墨坩埚、二等B型标准热电偶和Pt-Pd热电偶等。在此基础上进行了石墨坩埚的灌注和共晶点复现,并对复现的试验数据进行了相应的分析。结果表明本装置温度复现性可以达到0.2℃以下。

This paper designs a set for recurrence of the Pd-C high temperature eutectic point,which consists of a high temperature furnace,a temperature-controlling system,a pump,a gas protection system,a water-cooling system,a graphite crucible,a 2-class standard B-type thermocouple and a Pt / Pd thermocouple. The procedure of filling the crucible and reproducing the eutectic point are presented,and the experimental data are analyzed according to the recurrence results. It showed the reproducibility of temperature was less than 0. 2℃.
