Abstract. The individual construction elements are exposed to varying forms of loading, which correspond to the symptoms of degradation. In the analysis of degradation it is necessary to choose an approach that will lead to determine the actual causes of its origin. For determining the causes of degradation of objects currently wide variety of methods and equipment are available. It is necessary often to have in mind the economic viewpoint of the used method of analysis. It follows effort to create an approach for the educational process that passes information to students about choosing the methodologies and equipment. The present paper theoretically and practically introduces the possibility of a comprehensive approach that gives students the skills to detect the causes of degradation in selected parts of the energy equipment. This is an approach and examples for students studying technical fields. Students can apply this information during their studies in solving practical problems in the subjects such as Materials Science, Wear, Degradation of Metal Materials.
Degradation of technical objects is a natural phenomenon, but for users of these objects brings many problems. These problems are manifested by shortening lifetime, lowering safety and increasing costs for the technical operation of technical objects. This article analyzes the causes of degradation of parts steam generator using methods of microscopy. Degradation processes that occur most frequently in parts of steam generators are creep, corrosion and wear. The degradation occurred on the tube of convection superheater from steel CSN 41 5128. It was found that the inner surface was covered with corrosion products and was disrupted its cohesion. For search of the causes of degradation were used spectral analysis, microscopic analysis and determination of the weight of oxide layers according to CSN ISO 8407. Based on the results of analyzes, it was found that the occurrence of degradation is related both microstructure of pipes which did not comply with the required state and also with non-standard environment, which was exposed the inner pipe surface.
