Chemical heat treatment of steel
Pišek, David ; Molliková, Eva (referee) ; Němec, Karel (advisor)
This bachelor thesis deals with methods of chemical and heat treatment of steel. This thesis incorporates basic findings and ways of the performance of the chemical and heat treatment with detailed specialization in cementation and nitration of steels. This study is also focused on property of surface layers and their use. The primary aim of this thesis is to evolve an overview of the most frequent methods of chemical and heat treatment of steel and to evaluate advantages and disadvantages of individual methods for a practical use in industry.

Chemical-heat treatment of steels
Rozum, Jakub ; Pokorný, Zdeněk (referee) ; Sedlák, Josef (advisor)
This thesis deals with study of surface layers of low-carbon steels formed by chemical-heat treatment. The first three chapters consist of theoretical part of the thesis, there are explained basic physical principles of these technologies and described individual types, the third chapter deals with the application of chemical-heat treated low-carbon steels in mechanical engineering. The experimental part of thesis deals with analysis of surface layers of two low-carbon steels formed using plasma nitrocarburizing and gas nitrocarburizing. The properties of these layers are evaluated based on the results of mechanical tests (hardness tests) and observation of microstructure. The thesis is completed by discussion, where the achieved results are evaluated.

Teniferation - Unconventional Method of Carbo-nitration
Krejčí, Martin ; Gerstenberger, Jan (referee) ; Molliková, Eva (advisor)
Tenifer is a method of thermochemical treatment, concretely comes within the area of carbonitration methods. The saturation with nitrogen and carbon is carried out in special salt bath. Tenifer treatment achieves variety of final properties, which another method of treatment cannot ensure. Method is widely used in automobile and armament industry at this time. The purpose of this retrieval is to inform about principles, options and utilisation of this technology.
