Example Embodiment
[0066] Example 1-6
[0067] Examples 1-6 The corrosion-resistant alloy derivatives are 304 / Q235 composite hot rolled products. When the electrolysis is electrolyte, that is, the cation in the electrolyte is h. + , Anion is OH - Deep scales by the following steps:
[0068] S1, pretreatment, remove impurities in the surface of the corrosion resistant alloy derivatives;
[0069] S2, broken oxide, physical method to break the surface of the corrosion-resistant alloy derivative; therein, the physical method uses a jet impact method or a shot blasting method;
[0070] S3, surface cleaning, remove impurities in the surface of the corrosion resistant alloy derivative after step S2;
[0071] S4, local electrolyte scales, electrolytic derivation of the surface of the corrosion resistant alloy derivative;
[0072] In step S1-S4, the specific process parameters are shown in Table 1, wherein the local electrolysis processing is only for the surface of 304, and the partial electrical release ...
