Structural Properties of the Subsurface Groundgears and their Relation to the Parameters of the Barkhausennoise Analysis
 Blažíček, Dominik ; Malec, Jiří (referee) ; Pavloušková, Zina (advisor)
Batchelo thesis deals with non-destructive evaluation of surface integrity, which uses analysis of Barkhausen noise in dependence on microstructure of material, tested by metalllographic analysis. Their correlation is assessed on heavily loaded gears, which need to have high life time period. These gears were produced by continuous gear grinding, which influences the final integrity. The first part deals with the production of gears. The second part describes in details both experiments. Last part is devote to practical performance of these tests on produced gears.

Evaluation of the machined surface and subsurface properties using Barkhausen noise analysis
 Blažíček, Dominik ; Malec, Jiří (referee) ; Švejcar, Jiří (advisor)
Master thesis deals with the influence of milling to resulting surface integrity of gear tested by Barkhausen Noise Analysis technique. Two sets of gears milled by different machines by comparable parameters were used to solve the task. The testing of surface integrity was carried out after heat treatment and final grinding. It was experimentaly approved the effected surface/subsurface damage caused by milling remains in the material through the heat treatment. Based on these results, it can be assumed that different milling affects the resulting surface integrity after HT.

Structural Properties of the Subsurface Groundgears and their Relation to the Parameters Set by Diffractometer Method
 Červinka, Filip ; Malec, Jiří (referee) ; Pavloušková, Zina (advisor)
The bachelor‘s thesis deals with structual properties of the surface and subsurface ground gears. This thesis examines posibilities of affecting gear flank surface by continuous generating spur gear grinding process. There is used the measurement of hardness and microscopic observation of the structural properties for evaluating subsurface groundgears. This parameters are compared with values of residual stresses which was set by X-ray diffractometer method.

Verifying the possibility of using the sum of effective residualstresses concept (SERS) for the evaluation of materials surfaceintegrity
 Červinka, Filip ; Malec, Jiří (referee) ; Švejcar, Jiří (advisor)
The diploma thesis deals with surface integrity evaluation for different types of steels after case hardening and machining. This thesis compares Barkhausen noise analyses with residual stress depth profile set by X-Ray diffraction method with consideration of different penetration depth of both method. General purpouse of this thesis is verify the concept of the Sum Of Effective Residual Stresses as the index of part quality evaluation during manufacturing process.
