Specimens made of armco iron or pure iron were boronized during a time ≦; 1 minute with 1.1 vol.% BCl 3 in H 2 , and then their surfaces were investigated by scanning electron microscopy and X‐ray diffraction. The boride particles consist of FeB and Fe 2 B, they crow oriented on the substrate surface, e.g. the Fe 2 B (110) crystallographic plane is situated parallel to the (111) plane of α‐iron. The polycrystalline substrates are decorated by growing boride particles so that grains, twinning, etc. can be seen. There is a correlation between number per area and size of boride particles in early stages of layer formation and surface morphology in advanced layer growth.
