Název v původním jazyce

Effect of selected types of coatings on fatigue strength of nitrided steel with smooth surface and stress concentrator

Popis výsledku v původním jazyce

The work was aimed at research of effects of nitriding and selected types of coatings with nanostructured layers on fatigue resistance of nitriding steel with stress concentrator modelling characteristic situation at roots of gear teeth. The experimentswere performed on nitriding steel heat treated to relatively high strength and proof stress, on nitrided smaples and samples coated using method patented by Microcoat company - with nanostructured C layer deposited with modified cathodic arc technique. It was shown that in the case of notched specimens, potential unfavourable effects of nitriding and coating with the specific method were under repeated loading even more significant. Premature fatigue failures were caused by brittle fracture of surface nitrided and coated layers, respectively, and were affected by residual stresses.
