Utilization of surface texture evaluation in revolver production
Kolena, Robert ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
This diploma thesis addresses the issue of using the evaluation of surface texture in the manufacture of revolver with aplication to a cock. It deals with the detection of imperfections of production operations, the proposal of corrective measures and its implementation. The use of new grinding wheel was chosen as a corrective measure. The Rzmax parameter was used to specify the surface texture after miling and a combination of the Rzmax and Rpmax parameters was used to specify surface texture after grinding.

Aging and possibilities of its removal
Kolena, Robert ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
Thesis elaborates on current study of aging issues and describes its development caused by interstitial nitrogen and carbon atoms. It also points out how properties of materials are influenced. There are several removal options. The first one is heat treatment consisting of recovery and recrystallization annealing, the second one is binding of nitrogen atoms to chemical elements with higher affinity and third one is rolling with realization of small plastic deformation. Overall assessment and practical examples are also added.
