TL;DR: In order to control the hydrogen embrittlement problem of high-strength steel, electrochemical hydrogen permeation and precharging techniques were performed on Ni-, Ag-, Sn- and Cu-plated AISI 4140 steels to evaluate the benefits of impermeable coatings as mentioned in this paper.
Abstract: In order to control the hydrogen embrittlement problem of high-strength steel, electrochemical hydrogen permeation and precharging techniques were performed on Ni-, Ag-, Sn- and Cu-plated AISI 4140 steels to evaluate the benefits of impermeable coatings. From permetation and tensile results, the effectiveness of hydrogen impermeable coatings is in the order Cu, Sn, Ag and Ni

TL;DR: In this article, the hydrogen barrier efficiency of 8 μm Ni plated steel approached 100% after heat treatment at 850°C for 2 h. The reduction in hydrogen absorption resulted from the outer diffusive layer of Ni-Fe alloy formed at the nickel/steel interface.
Abstract: Hydrogen permeation transients for Ni plated steels were Ineasured at 25°C as a function of heat treatment. Nickel plating on steel significantly reduced the permeation rate and effective diffusivity. The hydrogen barrier efficiency of 8 μm Ni pl{lted steel approached 100% after heat treatment at 850°C for 2 h. The reduction in hydrogen absorption resulted from the outer diffusive layer of Ni–Fe alloy formed at the nickel/steel interface.
