Effect of the Heat Treatments on Corrosion and Erosion-Corrosion for Carbon Steel [PDF]

open access: yesEngineering and Technology Journal, 2011
The aim of present work is to study the effect of different heat treatments [full annealing ,normalizing ,and hardening and tempering at (300C° ,600C°)] on general corrosion and erosion-corrosion for a carbon steel type (C35) in 3.5wt% NaCl solution as ...

Use of Electrochemical Tests for Assessment of the Effect of Erosive Particle Size on the Erosion-Corrosion Behaviour of AISI 304L Austenitic Stainless Steel [PDF]

open access: yesMaterials Research, 2016
The degradation of AISI 304L stainless steel under static corrosion, liquid impingement and corrosion-erosion was studied using polarization curves. Static corrosion and liquid impingement tests were performed in 3.5% NaCl solution.

Flow accelerated corrosion and erosion−corrosion behavior of marine carbon steel in natural seawater

open access: yesnpj Materials Degradation, 2021
In this work, flow accelerated corrosion (FAC) and erosion−corrosion of marine carbon steel in natural seawater were electrochemically studied using a submerged impingement jet system. Results show that the formation of a relatively compact rust layer in

Studying and comparing the erosion-enhanced pitting corrosion of X52 and X100 steels

open access: yesInternational Journal of Electrochemical Science, 2012
The critical ratio of Cl− to HCO− concerning the corrosion rate has been determined with and without electrolyte erosion in 0.3 M NaHCO3 by using various concentrations of NaCl for X52 and X100 steels.

Improvement of Erosion-Corrosion Behavior of AISI 420 Stainless Steel by Ion-Assisted Deposition ZrN Coatings

open access: yesMetals, 2021
In this paper, a pragmatic technique has been developed to evaluate the erosion-corrosion behavior of three kinds of ZrN coatings (i.e., monolayer, multilayer, and gradient layers) which were deposited on AISI 420 martensitic stainless steel using an ion-

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
