摘要：

The effect of ion implantation on the resistance to hydrogen embrittlement of a high-strength low-alloy steel was investigated. The steel was a 4340 electro-slag remelted steel heat treated to a hardness of Rc 52. Platinum and palladium implantation was carried out on flat corrosion samples, notched round bar and precracked Charpy mechanical test samples. Implantation of the steel raised its corrosion potential in the noble direction but did not passivate the surface. The implantation also increased failure loads for notched samples. However, the effect of ion implantation on the hydrogen embrittlement resistance of precracked samples was minimal owing to the inability of the ion implantation flux to penetrate into the crack.
