Abstract |
A description is given of the process of selection of materials, their heat treatment sequences, and possible surface treatments for pawls of linear stepper motors for WWER nuclear power plants. The materials selected for the application were tested as well. The tests included measurement of hardness, impact toughness testing, metallographic characterization and high-temperature wear testing. In surface-treated specimens, the thickness and microstructure of the surface layer were determined. 14Ch17N2 steel proved to be the best candidate, as it showed a superior combination of properties for the application.
