In this work, the EN-GJS-400-15 cast iron was pack-borided in a powder mixture composed of 5% B 4 C, 5% NaBF 4 and 90% SiC at the three temperatures: 900, 950 and 1000° C for …
In this work, a kinetic model was suggested to evaluate the boron diffusion coefficient in the Fe 2 B layers grown on the Armco iron substrate by the powder-pack boriding. This …
In the present work, a diffusion model was suggested to study the growth kinetics of Fe 2 B layers grown on the AISI 1045 steel by the pack-boriding treatment. The generated boride …
