The influence of chromium as a diffusive additive in the boronizing treatment of AISI 4140 steel on the corrosion resistance of the coating evaluated by Electrochemical Impedance Spectroscopy (EIS) [PDF]
MATEC Web of Conferences, 2020 A large variety of protective coating is being used in industrial applications to improve the resistance of the metallic substrates against corrosion. The pack-cementation method for boronizing and borochromizing is effective to produce extremely hard ...

Synthesis of Boron Analogues of Enamines via Hydroamination of a Boron−Boron Triple Bond [PDF]
Angewandte Chemie International Edition, 2020 AbstractAn N‐heterocyclic‐carbene‐stabilized diboryne undergoes rapid, high‐yielding and catalyst‐free hydroamination reactions with primary amines, yielding 1‐amino‐2‐hydrodiborenes, which can be considered boron analogues of enamines. The electronics of the organic substituent at nitrogen influence the structure and further reactivity of the diborene
