Resumen

Novel results about the growth kinetics of Fe₂B layers produced by pulsed-DC powder-pack boriding (PDCPB) on AISI 1018 and 4140 steels were obtained. In the process, a DC-field is applied to ionize the B atoms and implements a programmable electronic control device (PECD) to maintain a constant B flux on both surfaces of the material. During PDCPB, the electrical resistivity (ER) was reduced due to the percolation of KBF₄ in the boriding media. Nevertheless, the increase of ER was caused by the depletion of KBF₄ after 1000s of the current induction. The PDCPB enhanced the growth kinetics of the Fe₂B layer around of 9% for both borided steels compared to those estimated in the conventional powder-pack process.
