Blackening treatment process of disc spring

When the spring is in the heated solution, the surface of the spring is corroded by alkali, Produce iron ions (ferrous compounds). Adding oxidant sodium nitrite to the alkali can change the oxidation process and form a dense oxide film (ferric oxide) on the spring surface. This oxide film is mainly composed of magnetic iron oxide, and the formation time of the oxide film is 30 ~ 60 minutes. If th...
