FIELD: process engineering.
SUBSTANCE: invention relates to thermal processing of steel parts. To ensure hardness, strength and preset mechanical properties, the parts are subjected to isothermal quenching in appropriate water-based medium. Said medium contains particles of ground mineral salt fractions. Then, ceramic diffusion ply is formed on steel part surface by adiabatic variation of steel lattice and structure via substitution of iron atoms with magnesium atoms and said particles of minerals. Said particles can diffuse in steel part surface ply.
EFFECT: non-aggressive safe solution.
