Structure and properties of diffusion boride layers on steels obtained at applying external magnetic field

Abstract

Investigated the structure, phase composition, microhardness and wear resistance boride coatings obtained on carbon steels at complex saturation with boron and copper in various physical and chemical conditions, namely carrying satiation without application of an external magnetic field (EMF) and in its simultaneous imposition. Established that the application EMF on carbon steels formed a continuous, homogeneous boride layer, thickness is 2 times higher than the boriding without EMF. Formation diffuse boride layers under the action EMF improves tribological characteristics and leads to an increase in wear resistance of 2.2 – 2.6 times.
