耐腐蚀

In the presence of PD , the dissolution rates of Cr and Ni in 304 matrix decreased obviously, and the molar percentages by which various components in 304 stainless steel dissolved were different from those in the absence of PD. AAS data indicated that regardless of the presence of PD the dissolution of Fe, Ni and Mn took the form of divalence, while Cr dissolved in the form of trivalence.
