Study of abrasion resistant layers created by laser cladding by means of methodes of dynamic shock impactor
Václavík, Ondřej ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
Diploma thesis studies the layers created by laser cladding and method of testing abrasion resistance of these layers using the method of dynamic shock impactor. In the theoretical part describes laser technologies and their applications, hardness testing and methods of testing of coatings. Proposed by the mechanical testing of the selected materials were carried out and evaluated in the experimental part. The conclusion summarizes final results of the experiment.
Cutting Performance of Cemented Carbide Tools with Nano-Crystalline PVD Coatings
Hudeček, Pavel ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
This thesis deals with the analysis of properties of hard coatings and wear resistance PVD coated technology. It focuses on the preparation, execution and evaluation of test coatings on the front ball milling cutter.
Optimalization of arc spraying parameters
Šildberger, Radek ; Filipenský, Jan (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated as a part of engineering studies branch M2307: Engineering Technology, Specialization 02: Forming and Welding Technology deals with the optimization of arc spraying parameters for TAFA 9935 facility.The theoretical part presents the principle of arc spraying, the description of the technological process and the types of additional materials. The practical part proposes the diffrent possibilities of TAFA 9935 arc spraying facility and the suitable additional materials. Several samples with diffrent parameters of spraying were created in order to test and analyse the coating quality.
