Obtaining and Study of the Properties of the Single-Phase Boride Layer on Different Steels

摘要

The process for obtaining saturated mediums with powder of the boron oxide basis, of amorphous boron and boron carbide, w itch is show, likely, to guarantee the formation of single-phase boride layer in the temperature range (700¨C 1100) ??C was proposed. The formation of layer was studied on samples of carbon steels, alloyed steel and of iron Armco. The results obtained show ed that the chemical composition of phases in the developed layers is determined by the nature the saturated medium and not by the intensive concentration of boron in the medium. For the same conditions of saturation it is observed that the thickness of the layer increases with the reduction of the carbon content of steel. The mechanical characteristics, the corrosion resistance and the qualitative characteristics of the texture of the single-phase layer were also studied
