Analysis of the Boronizing Process of High-vanadium Alloy Steel

Abstract

Abstract The high-vanadium alloy steel substrate surface was carried out by solid powder boronizing. The results showed that a certain thickness and compact structure of the boronizing layers could be obtained after boronizing. The thickness of the boronizing layer was about –53 μm; the thickness of the transition zone was about –36 μm, and the boronizing layer was combined with the substrate firmly. The boronizing layers consist of FeB and embed into the substrate like a spider. The alloying elements have little effect on the formation of sawtooth morphology in the boride layers. The thickness of the boronizing layers increased with the boronizing time and temperature increase, and the thickness of the boronizing layer has a parabola relationship with the processing time.
