Conclusions

  1. 1.

    Thermodynamic calculations were made to determine the possibility of aluminizing steel by the circulation method in an iodide medium on the basis of the disproportionation reaction 2AlI→2/3 AlI3+4/3 Al in the range of 1200–1400°K.

  2. 2.

    Even ductile coatings can be obtained on threaded samples of steel 25Kh1MF aluminized by the circulation method at 1210°K for 5 h. The aluminized coating is retained after oil quenching from 1160°K and tempering at 930°K.
