Microscopic Analysis of the Surface Morphology of Multilayer Structures of the AluminumAlloy - Silicon Type after Water Jet Cutting

The paper presents the results of an experimental work on the assessment of microscopic morphology of the surfaces obtained as a result of cutting with a Water Jet (WJ) water abrasive beam. The examination of microscopic structures was carried out with the use of Nova NanoSem 450 scanning electron micro-scope. The subject of analysis were the interfacial structures of multilayer structures connected in a vul-canization process with the surface of thin-walled parts made of AW-5754 aluminum alloy. The results of the research were compiled as a function of the technological WJ cutting conditions, such as feedrate and abrasive material flow.
