“…Likewise all three stainless steel types within the three-body region showed improved reproducibility with increasing volume fraction of abrasive. Rabinowicz et al [33] in their study of abrasive wear under a three-body regime reported that three-body abrasion leads to more reproducible test results compared with twobody. Batchelor and Stachowiak [30] have also suggested that three-body abrasion is more effective in removing the corrosion products, and by implication any passive film present, during abrasion-corrosion.…”

In this study, the synergistic effects of abrasion and corrosion on UNS S30403, S31603 and S32760 stainless steels have been investigated using a micro-abrasion test rig. The stainless steel samples have been studied under both pure abrasion (PA) and abrasion-corrosion (AC) conditions simulated by using silicon carbide based slurries in either distilled water or 3.5% sodium chloride solutions. Tests have been conducted at various abrasive concentrations (0.006-0.238 g/cm 3 ) and at 38 and 180 m sliding distance to enable the interactions between abrasion and corrosion to be better understood. Wear mode identification and regime mapping was used to establish the dominant wear mechanism at the different slurry concentrations. The synergistic effect has been quantified and related to the material composition and the grooving or rolling abrasive wear mechanisms present. The synergistic levels were typically positive and have been discussed in terms of their dependence on the integrity of the passive films and the repassivation kinetics. The three-body abrasion-corrosion rates for all steels were found to be 14 times higher than two-body abrasion-corrosion rates. S30403 shows weak repassivation performance with electrochemical activity being proportional to mechanical activity. S31603 showed a constant electrochemical activity over a variety of mechanical conditions, indicating a stronger repassivation performance than S30403. S32760 has the best repassivation performance with negative synergistic characteristics until abrasion rate are such that depassivation occurs and the electrochemical activity is then comparable to the other steels.

“…During the ball-cratering tests, it is necessary to ensure that either two or three-body abrasion mechanisms occurs [6]. There is some evidence that more reproducible results can be obtained with three-body abrasion mechanism [6,7]. Some authors sought the best conditions in order to obtain threebody abrasion and well-defined craters in some specific substrates [8,9].…”

Ball rotating micro-abrasion tribometers are commonly used to carry out wear tests on thin hard coat-ings. In these tests, different kinds of abrasives were used, as alumina (Al2 O3 ), silicon carbide (SiC) or diamond. In each kind of abrasive, several particle sizes can be used. Some studies were developed in order to evaluate the influence of the abrasive particle shape in the micro-abrasion process. Nevertheless, the particle size was not well correlated with the material removed amount and wear mechanisms. In this work, slurry of SiC abrasive in distilled water was used, with three different particles size. Initial sur-face topography was accessed by atomic force microscopy (AFM). Coating hardness measurements were performed with a micro-hardness tester. In order to evaluate the wear behaviour, a TiAlSiN thin hard film was used. The micro-abrasion tests were carried out with some different durations. The abrasive effect of the SiC particles was observed by scanning electron microscopy (SEM) both in the films (hard material) as in the substrate (soft material), after coating perforation. Wear grooves and removed material rate were compared and discussed.
