摘要:

利用动电位循环扫描的方法研究了PO₄^3-对304不锈钢亚稳态孔蚀及稳定孔蚀形核与生长阶段的影响。随着PO₄^3-浓度的增大，亚稳态孔蚀电位E_m和稳定孔蚀电位E_b值均增大，即PO₄^3-浓度的增大，抑制了亚稳态孔蚀和稳定孔蚀的形核。PO₄^3-增加导致亚稳态孔蚀的平均生长速度和电流峰值降低，从而增大了亚稳态孔蚀转化为稳定孔蚀的难度，抑制了稳定孔蚀形核。但PO₄^3-增加导致孔蚀再钝化电位E_p降低，使充分发展的稳定蚀孔更难于再钝化，其原因可能是磷酸盐膜在小孔孔口的沉淀会促进蚀孔生长的稳定性。

Abstract：

The effects of PO₄^3- on nucleation and growth of metastable and stable pitting were investigated by cycling potentiodynamic polarization. Both metastable pitting potential E_mand stable pitting potential E_bincrease with the increasing of PO₄^3- concentration. Higher PO₄^3- concentration results in lower average growth rate and peak current of metastable pitting, hence inhibits the nucleation of stable pitting. However, as PO₄^3- concentration increases, the repassivation potential of stable pitting E_p decreases, indicating that the repassivation of the pit is retarded. The reason is explained by the deposition of phosphate film around the pit mouth, which may promote the growth stability of the pit.

Key words： stainless steel pitting metastable pitting PO₄^3- nucleation growth
