一、前言 恒电位仪在合金相分析中的应用是近代合金相分析工作的一项先进技术。在相分析工作中恒电位仪主要用于测定极化曲线,选择合适的电解条件;在目的相与合金基体的稳定电位很接近的场合,进行恒电位电解,严格控制电解电位可以提高萃取精度和重现性;此外在相的化学性质相近的情况下,还可以利用相的电化学性质的明显差异进行相的选择性侵蚀和二次电解相分离工作。
I. Introduction The application of potentiostat in alloy phase analysis is an advanced technology in modern alloy phase analysis. In the phase analysis work potentiostatic instrument is mainly used to determine the polarization curve, select the appropriate electrolysis conditions; in the target phase and the stability of the alloy substrate is very close to the occasion, the constant potential electrolysis, strict control of the electrolysis potential can improve the extraction accuracy and Reproducibility; In addition, the similar chemical nature of the phase, but also can use the phase difference between the electrochemical properties of the selective erosion and secondary electrolysis phase separation work.
