What protection work should be done after metal surface treatment？

During various heat treatment, mechanical processing, transportation and storage of metal surface, it is inevitable that the metal surface will be oxidized, resulting in uneven thickness of oxide layer. At the same time, it is also vulnerable to oil pollution and adsorption of some other impurities. Oil contamination and some adsorbents, thinner oxide layer can be cleaned by solvent, chemical treatment, mechanical treatment, or chemical treatment directly. For severely oxidized metal surface, the oxide layer is thicker, and can not be directly cleaned and chemically treated with solvent. It is better to carry out mechanical treatment first.

The treated metal surface should be bonded as quickly as possible. Usually the treated metal surface has high activity and is more easily polluted by dust, moisture and so on.
