Influence Of Inclusions Size On The Nitrided Components Fatigue Life

Popis výsledku v původním jazyce

The paper is focused on the fatigue strength in material research. The aim was evaluation of influence of plasma nitriding technology to fatigue strength. Plasma nitriding is a thermo chemical procedure based on diffusion of nascent nitrogen into the surface of steels. This diffusion process is based on the solubility of nitrogen in metal matrix and nitrides creation. Especially at the point of fatigue fracture initiation there was in more detail the mechanism of fatigue failure examined. The inclusionarea is a place where usually the fatigue fractures arise. The inclusion is subjected to a thorough examination of the impact in terms of the size of inclusions on the tension amplitude dependence and an analysis of the inclusions chemical composition. Based on performed fatigue tests and won results can be submitted, that the plasma nitriding technology has a positive influence to fatigue strength of machine parts. The fatigue tests performed using the Instron R. R. Moore L2568 device e
