The practical aspect for evaluation of waste-water from metal plating
Válek, Roman ; Vávrová, Milada (referee) ; Doležalová Weissmannová, Helena (advisor)
The Galvanic Plating Technology is used by many branches of modern industry. Sizeable amounts of waste water are an integral part of plating technologies. It contains a versatile spectrum of chemical substances hazardous to the environment. This work focuses on monitoring the level and nature of waste water pollution resulting in primary production. Several indicators were selected to appreciate the quality of the effluent, which were defined according to the procedures. The possibility of quality monitoring process based on values of pollution was discussed after evaluating the results.

Galvanizing of steel components
Turkovič, Matúš ; Hanusová, Petra (referee) ; Zelený, Martin (advisor)
This thesis deals with galvanic, i.e. electrochemical plating. It is concerned with chemical and physical principles that accompanying plating followed by general overview of metal coatings as well as describes the process of their application. In detail, it is focused on nickel coatings. Part of the work is focused also on practical deposition of such coatings on steel samples as well as on study of effects of plating conditions on prepared coatings.

Development of an electric shock welding method for a combination of thin-film and thick-film structures
Hruška, Andrej ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
At the start this bacherol thesis deals with connection methods of terminals on thick and thin-films. One of the methods, which this thesis is mostly orientated on, is a terminal connecting with the shock welding method. The point was to test, if this method of connecting terminals is suitable for a combination of the thick and thin-films applications. The experiment included making of template for vapour plating, vapour plating of thinfilm on substrate, its galvanic plating and testing. Mechanical tensile strength of created welds was tested and in the end there was done the optical inspection of internal interface of welds.

Development and characterization of new method of interconnection between leads and thick film layer
Hurtík, Pavel ; Skácel, Josef (referee) ; Otáhal, Alexandr (advisor)
This work deals with different ways of interconnection between leads and thick film. It also includes the development and characterization of a new method of connecting leads, namely spot welding on thick film technology. The tips of the welding pen were modified to reduce the size of the resulting welds. To achieve a better-quality connection is used galvanic platting of contact pads. Final welds were then tested by mechanical strength testing (shear test, peel-test) and the optical method of evaluating the quality of the weld using metallographic cutting was used. Using this technology, a new inseparable connection can be achieved.
