The abrasive wear is a very intensive degradation process of machine parts in the mining, earth moving and coal based thermal power industries. The wear resistance is influenced by the working conditions and the parameters of worn material like hardness and microstructure. The present knowledge of material parameters and their influence on the wear by particles does not allow predicting lifetime of...
W artykule przedstawiono wybrane wyniki badań wstępnych warstwy wierzchniej wytworzonej przez azotowanie kąpielowe na stali zaworowej X45CrSi9-3. Określono wpływ azotowania na mikrostrukturę, skład chemiczny oraz twardość wytworzonej warstwy. Zaobserwowano wyraźny wpływ parametrów i warunków procesu na powstawanie twardych i kruchych wydzieleń: azotków, węgloazotków i tlenoazotków chromu i krzemu...
