Leaching of metals from steel samples in peracetic acid

In this paper, leaching behavior of metallic species from steel samples in peracetic acid was investigated. We compared the leaching efficiency between peracetic acid and acetic acid to estimate the role of peroxo functional group for the leaching. As a result, peracetic acid enhanced the leaching ability of metallic species from the high speed steel and the alloy steel samples. MoO 3 , Mo , MO 2 C, W, WO 3 , VC and MnO 2 were effectively leached by peracetic acid, while the stainless steel had a high resistance against corrosion by peracetic acid.
