Increasing the life of cutting blades by coating
Vodák, Marek ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
This Bachelor Thesis presents the possibility of increasing lifespan of cutting blades made of 19 436 steel, which are used for the production of stator sheets made of silicon steel. Its high amount significantly increases the hardness of the material, which adversely affects the lifespan of the tool blade. After selecting suitable methods, coating was chosen. Its use is limited by the resistance of the material to tempering with a maximum temperature of 520 °C. Therefore, it is necessary to choose a PVD method, more specifically arc evaporation, which runs at temperature below 500 °C. From a range of suitable coating the multi-layer FeinAl coating, which has excellent properties thanks to chemical composition and structure composed from many fine layers, was selected.
