Application of the corrosion tester in corrosion tests using the acoustic emission method

Emilianowicz Krzysztof, Supernak Milena, Ossowska Agnieszka

Polish Maritime Research

2022

nr 3

167--175

The article presents an innovative method of corrosion tests using the acoustic emission method and the corrosion tester. The problem of corrosion occurring in ballast tanks and tanks carrying petroleum products is discussed. The acoustic method is presented which, due to the use of a unique corrosion tester, is used to monitor the course of corrosion processes in steel. The principle of operation of the corrosion tester, its construction and its use in Non Destructive Testing (NDT) are described in detail. Corrosion test results, obtained with the use of a corrosion tester, are presented. An analysis and a short discussion of the obtained results are given. The results of both the acoustic and metallographic tests prove the possibility of detecting material damage occurring during the operation of the corrosion tester, allowing determination of the course and type of corrosion damage.

Monitoring of underdeck corrosion by using acoustic emission method

Emilianowicz K.

Polish Maritime Research

2014

nr 1

54--61

This paper presents first short characteristics of underdeck corrosion process as well as a problem of its monitoring. Next is described an acoustic emission (AE) method elaborated by Department of Ship Technology, Quality Systems and Material Engineering, Gdańsk University of Technology in cooperation with partners of CORFAT project realized within 7th EU Frame Program. Further are presented short characteristics of the emission process, used measuring instrumentation of Vallen Systeme GmbH, as well as TESTER, corrosion testing device, and a corrosion solution used in the tests. Finally, results of the tests performed on selected marine units, are presented. 1*GUT - Gdańsk University of Technology 2*TÜV- Austria 3*TESTER - a device used for simulation of corrosion processes without destruction of tested material surface. 4*Corrosive solution - a solution which catalizes corrosion processes in the tester 5*SMW S.A.- Naval Shipyard Co.
