Process parameters development for copper thin walls manufacturing via 3D printing
Klimek, Ľubomír ; Hutař, Pavel (referee) ; Paloušek, David (advisor)
In the work is used the processing of metallic material by the method of Selective Laser Melting. The main objective is to verify and describe the influence of the individual process parameters entering the production process when processing the alloy Cu7.2Ni1.8Si1Cr with SLM. This alloy contains 90 % copper. The first theoretical part of the thesis describes so far processed copper alloys with a high content of copper using the method of Selective Laser Melting. The practical part then deals with the specification of the main process parameters, which are optimized in the next part of the work solution. On the basis of the information obtained experimental bodies have been created, which will be tested and analyzed in several steps. The work focuses on thin-walled samples, which have a perspective use in the creation of highefficiency heat exchangers. The main results that the work deals with are the relative density and mechanical properties of the material. Also, great emphasis is placed on the resulting surface quality

Contactless sealing
Klimek, Ľubomír ; Galas, Radovan (referee) ; Omasta, Milan (advisor)
The aim of this work is factually and comprehensibly process the available information of contactless shaft seal. The introduction deals with clarifying basic concepts, historical development, and dividing the seals in general. Then it details the basic principles, advantages and disadvantages, and application of magnetic and labyrinth seals. The information included in this work can provide a basic overview for readers seeking information about this issue.
