Conclusions
-
1.
The method of saturating the surfaces of ferrous alloys with sulfur in aqueous solutions of hydrogen sulfide which has been proposed, considerably improves their resistance to scoring and seizing.
-
2.
Further treatment of sulfurized surfaces in a solution of potassium dichromate improves their resistance to corrosion.
-
3.
The method of sulfurizing which has been described has technical and economical advantages over similar processes and can be recommended for treating components made of ferrous alloys.
