On the project

Navrhnout technologii přípravy ochranných povrchových difúzních vrstev na litou niklovou superslitinu Inconel 713LC, která by vedla ke zvýšení životnosti tohoto materiálu v podmínkách nízkocyklové únavy za vysoké teploty

Description in English
The proposed project is directed to manufacture the composite, made up of a protective diffusion layer on the surface of cast nickel base superalloy Inconel 713LC, for high temperature application in an oxidizing and corrosive atmosphere under the operation of cyclic straining. The main goal is to find out an optimum technology of protective layer deposition base on the surface saturation with Al, and with Al in combination with Si and with Cr. The thermal regime of deposition and substrate surface treatment will be specified. The project solution will bring new complex data on the effect of deposition parameters on chemical, phase, structural, and mechanical properties of the protective layers. The structure and phase evolution of the layers exposed to high temperature will be analysed. The influence of the layers on the fatigue life of the superalloy will be obtained both in continuous cycling and in cycling with dwells at high temperature in air. Mechanisms leading to the composite degradation under the cyclic straining and under the high temperature exposition will be identified
