Repair of surface sliding
Teplý, Miroslav ; Vyplašil, Evžen (referee) ; Kubíček, Jaroslav (advisor)
The selection of suitable materials for the renovation of sliding shafts requires a comparison of several criteria. The main criteria were selected size shear strength under tensile stress lap bonded assemblies, resistance to adhesive wear and economic criteria. From the results of all tests is selected the most suitable friction material to repair worn out places of shaft. The technological process of sealing the shaft was drawn up on the basis of the literature, recommendations supplier of sliding materials and their own experience.

Renovation of casting molds by laser cladding technology
Cicha, Tereza ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
The diploma thesis deals with study of laser cladding technology and possibilities of its use in renovation of casting molds made of hot-work tool steel. The theoretical part describes methods of laser cladding, testing methods and characteristics of the base material and its heat treatment. In the experimental part the test clads, and the metallographic samples were made. The samples were evaluated in terms of macrostructure and microstructure, especially clad geometry, dilution, and defects like pores and cracks. Microhardness was also measured. In conclusion a technical and economic evaluation was performed.

Assessment of suitability welding modes MIG PULSE and MIG DOUBLE PULSE for repairing of forging die
Sotolář, Vojtěch ; Kubíček, Jaroslav (referee) ; Izák, Josef (advisor)
The bachelor thesis is focused on the renovation of forging dies by pulse methods, specifically MIG pulse and MIG double pulse. The subject of this research was a part of forging die made of steel Wr.Nr 1.2343ESU (H11), however the problem was simplified to the welding of four prisms with the same type of material. The main goal was to evaluate whether these methods can be utilized to speed up the entire renovation process as the welding speed is its undeniable advantage. There were used two types of welding materials to assess the suitability of the renovation. For the tough weld was used the martensitic material CRONITEX RC 58 and for the interlayer was used austenitic-feritic material WELCO A1660. The assessment was conducted based on the non-destructive visual test and also based on destructive tests of macrostructure, microstructure and hardness measurement. The experiment results showed that configuration of tough material with interlayer is inappropriate. The most suitable process seems to be the welding of only tough layer without any interlayer.
