Analysis of heat treatment effect on dimension shift
Kunkela, Ondřej ; Jaroš, Aleš (referee) ; Kolář, Ladislav (advisor)
This bachelor thesis focuses on chemical-heat steel processing, mainly to the size change caused by the process itself. To look into the problem closely some samples from various materials and of various size have been made. The samples were measured before and after the ionic nitridation. Likewise the samples, the real peaces were measured, some of them were ionic nitridated and some were cemented. The real pieces were made from the same material but they differed in size and shape. Subsequently, all the figures were processed and assessed.

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.

The effect of surface hardening on fracture behaviour of steels for gear wheels
Dlouhý, Ivo ; Holzmann, Miloslav
Three procedures of surface hardening (carburising, nitriding and surface quenching) combined with six structural steels have been followed. The properties evaluation is based on assessment and interpretation of load - deflection traces, obtained by means of instrumented impact tester and/or at static testing of notched bend specimens. Knowledge obtained has been formulated into generalised schematics of fracture behaviour.
