摘要：
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 permeation and tensile results, the effectiveness of hydrogen impermeable coatings is in the order Cu, Sn, Ag and Ni. To protect high-strength steels from hydrogen embrittlement, coating with a low-hydrogen-permeable metal is a practical method.
