“…In many cases, the wear rate in solutions is usually larger than that due to dry wear. [14,15] Because of the combined action of mechanical and electrochemical mechanisms, the volume loss due to the synergistic effect of abrasion corrosion often exceeds the sum of the separate abrasive and corrosive wear losses. [16] Wear may result in the elevation of surface temperature, surface activation, and the removal of the oxide film or passive film and thus may accelerate oxidation or corrosion.…”

Wear corrosion of alumina particulate-reinforced 6061 aluminum matrix composites in a 3.5 wt pct NaCl solution with a revised block-on-ring wear tester has been investigated. The studies involved the effects of applied load, rotational speed, and environments (dry air and 3.5 pct NaCl solution) on the wear rates of materials. Also various specimens with Al 2 O 3 volume fractions of 0, 10, 15, and 20 pct were employed in this work. Electrochemical measurements and electron micrographic observations were conducted to clarify the micromechanisms of wear corrosion in such metal matrix composites. Experimental results indicated that the wear rate of monolithic 6061 Al in either dry wear or wear corrosion was reduced by adding alumina reinforcements. However, the effect of volume fraction on wear rate is only minor in dry wear, while it is significant in the case of wear corrosion. Wear-corrosion tests also showed that the corrosion potential shifted to the active side and the current density for an applied potential increased with the decrease of Al 2 O 3 volume fraction in the materials and the increase in applied load and rotational speed. Although the incorporation of reinforcement in these aluminum matrix composites was deterimental to their corrosion resistance, the influence on wear corrosion was favorable.

“…It has been noticed in many articulating systems that abrasive wear modifies the sensitivity of the constituting materials to corrosion, and on the other hand, corrosion affects wear resistance by changing the abrasion condition between moving contacting parts [3]. This usually expedites the tribo-chemical degradation of the material [4][5][6][7][8][9]. In the present study we investigate the influence of corrosion on abrasion performance of structural steel.…”

“…2(b). Liquids with stronger corrosivity are extensively reported to result in higher wear rate [4][5][6][7][8][9]. The common explanation attributes this higher wear rate to the rise of chemical wear, the amount of wear caused by periodic removal of the passive film from the metal surface due to the abrasive action of the counterpart [13].…”

“…As a result, the plastic bulge area is formed on the material surface [38]. Due to different electrochemical features between the un-deformation area and the plastic deformation area on the material surface, 'strain differences corrode cells' is formed [39,40]. Because of a high physical and chemical activity, flanks of the furrow lose electron easily and become anode.…”

Fe-Cr alloys with different chromium contents have been designed in the current study for the ball mill liner working in weakly alkaline slurry. The structure, mechanical properties, corrosion behavior and erosion-corrosion behavior of the alloys were investigated. The result shows that with the increasing Cr content, the hardness and corrosion resistance of the alloy are improved. However, the impact toughness of the alloy shows a decreasing trend with the increase of Cr content. The alloy with the Cr content of 6.978 wt% exhibits the best erosion-corrosion resistance among all alloys in the weakly alkaline slurry. Further analysis shows that the erosion-corrosion mass loss of these alloys in weakly alkaline slurry mainly results from pure mechanical erosion and the interaction between corrosion and erosion. The damage process has also been discussed by interaction models of corrosion and erosion. The result is beneficial to provide reference for selection and development of erosioncorrosion resistant material for ball mill liner working in weakly alkaline medium.
