本测定法是由作为本分会活动之一的有关题目的讨论结果成文的。1.适用范围本测定法适用于藉动电位法测定各种不锈钢的点蚀电位(V′c)。为了各测定者之间的数据相互比较,本法中规定了溶液条件等。2.测定法的概要使用恒电位仪,在3.5%食盐水中,试样电极为阳极,以动电位法从自然电位朝正方向极化,测定阳极化曲线,由此求出点蚀电位。 This test is based on the results of a discussion of relevant topics as one of the club’s activities. 1. Scope This method is suitable for measuring the pitting potential (V’c) of various stainless steel by potentiometry. In order to compare the data between the various test set, the provisions of the Act solution conditions. 2. Summary of Measurement Methods Using a potentiostat, the sample electrode was anodic in 3.5% saline solution, and the pitting potential was obtained by measuring the anodization curve by potentiodynamic polarization from the natural potential in the positive direction.
