In this investigation, plasma ion nitriding was conducted to improve the hardness, wear resistance, and hydrogen embrittlement resistance of aluminum alloys. To research the surface characteristics and hydrogen embrittlement resistance of the nitrided layer, indentation experiments, scratch experiments, friction experiments, FE-SEM, XRD, EDS, and 3D laser microscopic analyses were conducted. An AlN layer was observed on the surface after plasma ion nitriding. As a results of the indentation experiment, hardness (HIT) of the nitrided layer decreased from 1370 MPa to 749 MPa and 538 MPa, respectively with hydrogen embrittlement for 3 hours and 6 hours. As a result of hydrogen embrittlement, adhesion between the base material and nitrided layer tended to decrease from 6.54 N to 2.50 N. In addition, as a results of the friction experiment, the section where the nitrided layer was maintained was shortened as the hydrogen embrittlement time increased.

“…The hydrogen which is introduced into the metal via electrochemical process or gaseous absorption leads to hydrogen embrittlement of the material which results in the decrease in the mechanical properties such as toughness and ductility. Moreover, hydrogen embrittlement even results in hydrogen induced cracking or brittle fracture [4][5][6] which finally causes the failure of the material. A component or structure can be contaminated by hydrogen in various stages of its life [7].…”

The characteristic of hydrogen uptake and diffusion in the cold-rolled silicon steel was investigated by electrochemical hydrogen permeation technique performed under different cathodic charging current density and cold-rolled thickness reduction degree. The results indicated that anodic permeation current density increased with increasing cathodic charging current for the specimens. Moreover, the anodic steady state permeation current density and the solubility increased with an increase in the cold-rolled thickness reduction degrees. The breakthrough time of hydrogen in the specimens was shortened with increasing thickness reduction degrees, and the value of the hydrogen diffusivity decreased gradually with increasing thickness reduction degrees.
