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 .

Návrh antikorozní ochrany u strojů pro aplikaci hnojiv v zemědělství
Mareček, Tomáš
The diploma thesis is focused on proposal corrison protection on machines for application of fertilizers in agriculture. The theoretical part describes the distribution of machines for fertilizer application, issue and species of corrosion. The next section discusses the electrochemical corrosion, its principles and distribution. The final section is an experiment that has analyzed the possibility of using five kinds of corrosion protection evaluation of corrosion tests in laboratory.
