... boriding ferrous alloys is a single-phase boride layer consisting only of Fe 2 B. In some cases, a dual-phase layer consisting of an outer darker-etching phase of FeB and an inner bright-etching phase of Fe 2 B may also be formed. The formation of either a single- or dual-phase boride layer in steels...

... boron diffusion rate. Boron content at the surface increases at a more rapid rate as boron continues to flux from the powder into the surface at a fast rate while diffusing into the substrate at a slow rate. Higher alloy steels are much more prone to having dual-phase Fe 2 B-FeB layers as shown...
