Plasma overlay welding of cobalt alloy
Paleta, Petr ; Daněk, Ladislav (referee) ; Sigmund, Marian (advisor)
The thesis deals with plasma overlay welding of cobalt alloys. In the theoretical part of the thesis, suitable cobalt alloys for plasma overlay welding were described, out of which cobalt alloy Stellite 21, was chosen for overlay welding for particular part. Subsequently, the plasma overlay welding machine PPC 250 PTM and the torch PHP 250 S, used in the practical part, were described. In the practical part were debug overlay welding parameters and suggest the suitable overlay welding procedure for particular part.

The construction of the magnetic metal powder separator
Papaj, Lukáš ; Suchý, Jan (referee) ; Paloušek, David (advisor)
This thesis deals with the design of construction for recyclation metal powder, which is used in multi-material 3D printing with SLM technology. More specifically it is separation of mixed metal powders by magnetic separator, which is capable of separating two powders with the same distributions. Based on knowledge from industrial separators and successful experiment method of separating with magnetic drum was chosen, on which is equally driven metal powder from vibrating feeder. In executed experiment was discovered, that the method is appropriate for separating non-magnetic powder but for high quality separation of magnetic powder must be adjusted speed of feeding. Next was processed drawing documentation for this variant. By this documentation can be separator assembled and used in laboratory for separating metal powders.

Review of materials used for the manufacturing by the Selective Laser Melting technology
Skalický, Petr ; Vrána, Radek (referee) ; Koukal, Ondřej (advisor)
This bachelor thesis aims to provide an overview of metallic materials (powders), which are used in the manufacture of parts and models with SLM (Selective Laser Melting) technology. It contains basic information about Rapid Prototyping (RP) technology and more detailed description of basic methods of RP, especially SLM. Next is a description of manufacture powders methods and its properties. The last section contains an overview of powdery materials as powders made of pure metal (one kind of metal material) and powders produced from metal alloys. This review focuses on the most important and most widely used materials for the manufacture of parts using SLM.
