Commensurability of the Structures of Boride Layers
The interaction of solid NH4HCO3 with iron, where the ammonia product has been adsorbed nondissociatively to iron surfaces at low temperatures  was investigated. The nitride clusters formed on steel substrates modified the surface morphology and characteristics of the substrate and influenced their adhesion during subsequent procedure of coating. In our case, efforts were made to decorate the steel substrate in order to influence the base metal reactivity towards boron and its ability to react and form stable compounds with boron . Boride layers on steel are examined by means of SEM and XRD analysis. The decorated surface was observed by FTIR method.
