Abstract
This study contains a short overview of sulfur nitriding methods, i.e. a modified version of nitriding. Thisinformation is accompanied by the results of our own tests of nitrided and sulfur-nitrided coatings with theaddition of MoS2 in the scope of structure assessment by means of a scanning microscope – SEM/EDS andthe results of tribological tests performed under dry friction conditions on the T-05 apparatus for four variantsof thermo-chemical treatment. In tribological tests, the degree of wear was observed by measuring the weightloss of both samples and counter-samples, and the beneficial effect of sulfides on reducing wear was indicated,with the sulfur nitriding variant with MoS2 added being the most advantageous. In this case, the lowest degreeof wear was found for the friction pair with a sulfur-nitrogen coating reinforced with MoS2, which may leadto extending the operating time.
