Embodiment approach
[0038] As an implementation of the embodiment of the present invention, the diameter of the drawn iron-chromium-aluminum alloy wire is 4-12 mm.
[0039] S2, placing the clean iron-chromium-aluminum alloy wire into a nitrate solution for passivation to obtain an iron-chromium-aluminum alloy wire with a passivation film;
[0040] This process has two functions: firstly, it has the function of neutralizing the residual alkali solution; secondly, it has the function of passivation, and its electrolyte has oxidizing properties, which can not only oxidize the metal ions and the replaced hydrogen atoms, but even the atomic state. Oxygen can oxidize on the surface of the alloy, and the chemical potential of atomic oxygen is high. At the same time as the oxidation of the electrolyte, atomic oxygen will chemically adsorb on the surface of the alloy. In chemical adsorption, O has electron-withdrawing properties and Metals have the property of losing electrons, so O can extract electrons ...
Embodiment 1
[0062] Embodiment 1 provides a kind of preparation method of the iron-chromium-aluminum alloy with pink oxide film, as follows:
