Conclusions 1. Surface saturation of steel with boron in the process of electrolytic boriding is accompanied by diffusion redistribution of carbon and alloying elements. The direction and intensity of the transfer of carbon and alloying elements depend on their affinity for boron and the phases formed. 2. The redistribution of carbon causes decarburizing of the zone of borides, and also the zone of α phase in silicon steels, and saturation of the transition zone. The highest carbon concentration in the transition zone exceeds the average concentration in the alloy by 20–100%; the character of the distribution depends on the structure of the boride case. 3. Silicon diffuses into the core during boriding, enriching the zone of α phase and promoting the formation of three zones in the layer (borides, α phase, and transition zone) that differ sharply in composition and have substantial effects on the properties of the boride case. 4. Chromium and manganese diffuse to the surface during boriding, enriching the zone of borides, but with no substantial effect on the structure of the boride case.
