Iron-based powder metallurgy parts

Because of the iron-based powder metallurgy parts processing technology has excellent antirust function of the steam and has been widely used.It is to place parts in a heating furnace, under a certain temperature, parts and the supersaturated steam oven of our factory contact, who come into contact with all surfaces of steam iron atoms, including part outer surface and inner surface of open pore, iron atoms and steam oxidation reaction, generate a layer of oxide film.When the layer of oxide film is mainly composed of Fe3O4, the oxide film is very dense firmly stick covered on the substrate surface, it has excellent antirust function.Good processing result, which can make the appearance of parts is very smooth and beautiful blue-black metallic luster.
