Corrosion resistance of sintered sulfidized iron-base materials
- 15 Downloads
The presence of free structural carbon slightly lowers the corrosion resistance of iron-graphite alloys. The addition of Sulfides decreases their corrosion resistance by 15–20%.
Impregnation with machine oil or paraffin wax increases the corrosion resistance of porous sulfidized materials and enables their storage life to be extended 2–5 times.
At porosities below 10–12%, the weight gain of corrosion products is directly proportional to porosity.
The rate of corrosion of interparticle contacts in a porous material is 4–5 times higher than the rate of surface corrosion, and for this reason particular importance must be attached to the protection of porous articles against corrosion.
