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.
