Steam Treatment: Reliable Steam Treatment from Huaxiao
Steam Treatment heats sintered PM parts in superheated steam to grow a hard, black iron-oxide surface that seals pores and improves wear and corrosion resistance.
How Steam Treatment Works
Sintered parts are exposed to high-pressure steam; the iron reacts to form a bonded oxide layer that closes surface pores and hardens the skin.
Steam vs. Infiltration
Steam treatment improves surface wear and seals pores cheaply; infiltration adds bulk strength via copper.
Materials
- Sintered iron—bushings
- Steel PM—structural
- Ferrous PM—hardware
Industries
