The effects of particle angularity on low-stress three-body abrasion-corrosion of 316L stainless steel

Corrosion Rate and Wear Mechanisms Comparison for Aisi 410 Stainles Steel Exposed to Pure Corrosion and Abrasion-corrosion in a Simulated Marine Environment

“…There are some works in literature that have used the same contact configuration and similar test rigs. This configuration consist in a metallic sample (work electrode) having contact against a sliding counter body submerged in an aggressive medium with the presence of suspended abrasive particles (abrasive slurry) [12][13]. This machine adaptation allows the sample/electrode holder to work also as load applier trough a lever arm system.…”

On a multiphysics approach to modelling the erosion–enhanced corrosion of low–alloy carbon steel in chloride containing environments

“…Whereas corrosion and erosion are relatively well understood as separate processes, the synergy term is a multifactorial problem [2][3][4][5][6] that requires taking into account: 1) properties of the alloy target [7][8][9][10][11][12][13][14][15]: its hardness, modulus of elasticity, toughness, chemical composition and microstructure, 2) characteristics of the dispersed phase [16][17][18][19][20][21][22][23][24][25][26]: its density, hardness, size, angularity and concentration of the slurry particle are the most relevant, as well as 3) properties and conditions of the flow medium in which the particles are suspended [27][28][29][30][31][32][33][34][35][36][37]: its velocity, impact angle, viscosity, pH, pressure and chemical composition.…”

Low Stress Abrasion-Corrosion of High-Cr White Cast Iron: Combined Effects of Particle Angularity and Chloride Ions

“…A higher load resulted in a much more effective particle grip by the rubber counterface; hence an enhanced depassivation of the WE1 (high-Cr WCI). Previous two 36 and three-body 11 tribocorrosion studies showed that current measured was proportional to the applied load. In this investigation only two data points were obtained, insufficient to verify whether a similar correlation exists, but this was not the scope of this research.…”

“…The finely-grained tribolayer formed on the matrix had similar characteristics to those found underneath the tribo-corroded AISI 316L stainless steel after three-body abrasion-corrosion with glass beads particles. 11…”

“…a) Comparison of the mean currents obtained in potentiostatic three-body abrasion-corrosion tests of high-Cr WCI and 316L stainless steel abraded by semi-angular silica sand particles. The 316L SS sample tests were carried at 61 mm/s tangential speed and −0.1 V/SSE applied potential in 3.5 wt% NaCl near neutral solution 11.…”
