Hodnocení korozní odolnosti návarových materiálů po tepelném ovlivnění

Abstract

This Thesis studies the corrosion resistance of weld deposits of material after the heat affected. In the theoretical part of the paper deals with the problems of corrosion damage and properties of high-alloy materials. The experimental part of this work is to simulate the operating conditions (700 °C, aggressive environment) and output measurement to determine whether there is a relationship between corrosion resistance, thermal exposure time, structural stability and the degree of alloying materials used. The investigated samples are high alloyed materials based on Cr-Ni. It is stainless steel and nickel alloys.
