Effect of hydrogen embrittlement on mechanical characteristics of DLC-coating for hydrogen valves of FCEVs (www.nature.com)

Diamond-like carbon (DLC) coating is a surface coating technology with excellent hydrogen permeation resistance and wear resistance. However, it is difficult to completely prevent hydrogen permeation, and when hydrogen penetrates into the coating layer, the DLC coating is adversely affected. Therefore, we investigated the effect...
