Abstract
- Abstract: In the present investigation, 35CrMo alloy steel was gas oxynitrocarburized at 550°С, 570°С and 610°С for 2h by applying a low-temperature gas multi-elements penetrating system. Microstructure, surface composition, case depth, microhardness, wear and corrosion resistance were analyzed. The compound layer consisting of γ′-Fe4N and ε-Fe3N and oxide layer of Fe3O4 and Fe2O3 were formed on the ground reference surface after treated. Compared with the conventional gas nitrocarburizing, a larger effective case depth was obtained successfully in a short time after treatment. The microhardness and the properties of wear and corrosion resistance were improved obviously and the properties of samples treated at 570°C are optimum when compared with the samples treated at 550°С and 610°С for the same duration.
