Use of acoustic emission technology to assess corrosion of materials
Procházka, Adam ; Vašíková, Simona (referee) ; Binar, Tomáš (advisor)
The thesis deals with the description of acoustic emission as a non-destructive testing method and its use in the detection of material corrosion. The first part describes the theoretical principles dealing with the explanation of what acoustic emission is, how it is defined according to the standard, what are the types of acoustic emission and how it is tested. It then discusses corrosion, the types of corrosive environments where corrosion occurs and the types of corrosion tests. It also describes where acoustic emission has been used in practice and what experiments it has been used for in terms of material monitoring. The next part of the paper describes the experiment of acoustic emission measurement on grey cast iron samples, describes the fabrication of the samples, the use of corrosion protectors, and the placement of the samples in a condensation chamber for continuous testing. The last part is the evaluation of the results .

Evaluation of the use of non-destructive methods of acoustic emission on materials
Vašíková, Simona ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
This master thesis is about acoustic emission itself and acoustic emission as a nondestructive method of testing materials. There are different types of metal materials corrosion too. In this thesis is possible also find corrosion protective methods. There are practical examples of use the acoustic emission method at metal materials corrosion from automotive, aviation, food processing and manufacturing industry with construction and civil engineering examples. The experimental part is focused on samples preparing and measuring the acoustic emission signals during continual corrosion process of grey cast iron in condensational corrosion chamber. These results are supported and completed with metallographic analysis.
