Abstract
The results of studying the corrosion resistance of the homogenous and heterogeneous welded joints of nickel alloys (Monel 500, Inconel) and stainless steel in a deaerated NaOH melt at a temperature of 500°C are presented. The effect of homogenizing annealing of the welded joints on their corrosion behavior is investigated. The microstructure and the phase composition of the surface layers formed on these materials in the NaOH melt during corrosion tests are studied by X-ray diffraction and electron microscopy.
