Abstract
Purpose
The purpose of this paper is to study the cavitation erosion stages of AA5083 by electrochemical noise (EN).
Design/methodology/approach
EN technology including noise resistance and fast Fourier transform were used to characterize the electrochemical process during the cavitation erosion process.
Findings
AA5083 suffers from uniform corrosion during the cavitation erosion process. The whole cavitation erosion process can be divided into three stages: incubation stage, acceleration stage and steady-state stage. EN signals showed obvious differences in different stages of cavitation erosion.
Originality/value
EN technique is a suitable method that can be used to study cavitation erosion mechanism and identify cavitation erosion stages.
