试验面选取对碳钢点蚀电位测量的影响

Effect of test-surface′s selection on measuring pitting potential of carbon steel

采用金相分析技术和准稳态极化试验研究了试样试验面选取对碳钢点蚀电位测量的影响.结果表明,当不同试验面的夹杂物形态有很大差异时,测得的点蚀电位有较明显的差异.

The effect of test\|surface′s selection on measuring pitting potential of carbon steel is researched by metalographical analysis technique and quasi\|steady\|state polarlization technique. The results show that the obvious difference of pitting potential measured on different test surfaces will be produced if there is obvious difference of the inclusion's distribution between different test surfaces of a steel.
