Application of natural gas to thermochemical treatment of steel parts

Autor: A. T. Chaukin, V. L. Kozlov, I. M. Rukina

Publikováno v: Metal Science and Heat Treatment. 26:705-708

1. Carburizing and carbonitriding endothermic atmospheres with additions of natural gas and ammonia produce the optimum amounts of carbon and nitrogen in the diffusion layer, thus improving the wear and fatigue resistance of the steels studied by 30%

Features of failure formation for a diffusion layer after chemicothermal treatment of steel

Autor: V. L. Kozlov, I. M. Rukina, I. P. Zhegina

Publikováno v: Metal Science and Heat Treatment. 25:146-147

From the data of microfractographic analysis, a diffusion layer formed by carbonitriding the test steels exhibits more local ductility during failure than with carburization.
