Conclusions

  1. 1.

    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%.

     
  2. 2.

    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.

     
  3. 3.

    At porosities below 10–12%, the weight gain of corrosion products is directly proportional to porosity.

     
  4. 4.

    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.
