Conclusions

  1. 1.

    Diffusion impregnation of steel with boron and silicon followed by sulfur impregnation produced two types of coatings. Coatings of the first type are formed at 1000°C when silicon forces iron boride off the surface, while coatings of the second type are formed at 900°C when silicon to some degree hinders boron diffusion to the surface. Sulfur diffusion does not affect the surface microstructure.

     
  2. 2.

    The wear-resistance and galling-resistance of parts subjected to diffusion impregnation with boron, silicon, and sulfur are 1.6–2.1 times higher than for parts subjected to boron impregnation alone.
