The Structure and Properties of Austenitic Steel Prepared by the Cold Spray Method and Selected Laser Melting Technology
Osička, Filip ; Šmíd, Miroslav (referee) ; Hutařová, Simona (advisor)
This bachelor's thesis focuses on the comparison of two different technologies, specifically Cold Spray (CS) and Selective Laser Melting (SLM), and their effects on the properties of austenitic unstabilized stainless steel AISI 304L. The difference between these technologies is determined by the difference in their physical principles and thus their different practical applications. The theoretical part of the thesis describes in detail the principles of CS and SLM technologies applied to stainless steel. The experimental part describes the procedures for evaluating samples that were created using CS and SLM technologies, with each sample being produced under different process parameters. The analysis included not only the samples prepared by these methods but also the input material in its original state. The microstructure of the produced materials was extensively examined under a light and scanning electron microscope. Furthermore, porosity, microhardness, and flexural strength were determined. The results of the individual measurements are compared and subsequently discussed in the context of the available scientific literature.
