The effect of steam treatment on powder metallurgy products

After simple processing of powder metallurgy products using the steam, you can get ideal anticorrosive property, because the iron atoms on the surface of the oxidation reaction with steam, to produce a layer of oxide film, anti rust performance of the products is therefore improved a lot. And because of the hardness of the film is very high, so once after the adhesion on the surface of a product, its abrasion resistance and wear resistance will change.

Powder metallurgy products have an important role in the steam treatment, that is, sealing holes. In addition, the effect of the powder metallurgical products after steam treatment on the dimensional accuracy is not very large. The whole process will not pollute the environment, and the energy consumption is not high.
