Electrochemical-mechanical corrosion phenomena

, 2021
The substantial number of parameters and their interdependence makes the modelling and prediction of erosion-corrosion rates a challenging task, yet owing to increasing computational capacity one that is potentially solvable. To accurately estimate the rate of material loss, universally accepted explanations of the mechanisms of combined erosion and ...

Electrochemical Behavior of Corrosion on Borided and Non-borided Steel Immersed in NaCl 3.5% and HCl Solutions

ENP Engineering Science Journal
This paper assesses the ability of borided and non-borided Z80 WCrV 18-04-01 steel to resist corrosion by employing linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) methods.

Some peculiarities of corrosion of wheel steel [PDF]

Transport Problems, 2009
Corrosion mechanism and rate of different chemical composition and structural condition of wheel steel were investigated. It was shown that “white layers”, variation in grain size and banding of wheel steel structure results in corrosion rate ...

Mechanism of Crevice Corrosion

Corrosion, 1964
Failure of structures and of many types of automatic equipment is often due to crevice corrosion. Differential aeration was advanced some time ago as a major cause of such attack. The present investigation was made to demonstrate other factors in the mechanism of crevice corrosion.
