“…It has been discovered that increasing the time length leads to better mass loss for up to 15 hours, after which it becomes nearly steady. Te constant behaviour after ffteen hours could be due to a variety of factors; for example, Advances in Materials Science and Engineering in the case of aluminum alloys, an oxidation reaction forms an oxide flm layer on the surface of the metal, which acts as a protective coat by limiting weight loss over time [30,31]. Furthermore, as the testing time increases, a continual efect of abrasives will be felt on the targeted surfaces.…”

The current work investigates the erosion-corrosion behaviour of thermally sprayed tungsten carbide-10% nickel (WC-10% Ni) coatings placed on the AA6061 aluminum alloy. The AA6061 aluminum alloy was coated with tungsten carbide –10% nickel coatings utilising a high-velocityoxy-fuel (HVOF) spray method. The microstructure and hardness of thermally sprayed coatings were examined using a scanning electron microscope (SEM) and a Vickers hardness tester. The slurry erosion-corrosion wear tests were carried out by varying the parameters of the slurry erosion process, such as testing time, slurry content, slurry speed, and impinging particle size, on the erosion testing equipment. The data demonstrated that when slurry concentration, slurry speed, and impinging particle size increased, so did the slurry erosion-corrosion wear loss. The wear processes of uncoated and thermally sprayed tungsten carbide –10% nickel have been examined using SEM and a 3-D confocal microscope.

It has been further reported that fracture and fragmentation of reinforcing particles take place during erosion if the reinforcement size is smaller than the size of the erodents.…”

“…However, limited attempts were made on the solid particle erosion of these materials. [11][12][13][14][15][16][17][18][19][20][21][22] Different investigators have reported different observations. Some reports suggested that AACs suffer from higher erosive wear compared to the base alloy at impingement angles greater than 20 deg.…”

Erosive wear behavior of the as-cast and heat-treated Al alloy and the Al-alloy-SiC particle composite against Al 2 O 3 erodent has been examined at different angles of impingement (15 to 90 deg). It has been noted that the cast Al alloy exhibited a higher erosion rate than the heat-treated alloy and composites irrespective of the angle of impingement. It is noted that the as-cast and heat-treated Al alloy exhibited a maximum wear rate at the 45 deg angle of impingement, whereas the composite, in as-cast as well as in heat-treated conditions, showed a maximum erosion rate at the 60 deg angle of impingement. Subsurface studies of the alloy and composite confirm that the material loss, during erosive wear, is primarily due to microcutting/microplowing (i.e., abrasive-type) and microfracture (i.e., impact-type) actions. At a low angle of impingement, the abrasive type is the dominating factor for material removal, and at a higher angle of impingement, both the impact-type and abrasive-type actions play critical roles. The impact type is mainly localized at the tip of the erosion profile, while the abrasive type takes place along the sidewalls of the profile. This is explained on the basis of the erosion mechanism using a schematic diagram.

“…The most important parameter in assessing the performance of the composites in erosive conditions is whether the reinforcement particle or fiber undergoes fracture or not. Two basic mechanism were identified for the slurry erosion of MMCs by Turenne et al [16] namely matrix cutting and reinforcement fracture. In their works on slurry erosion of an Al-Mg alloy MMC containing short Al 2 O 3 -SiO 2 fibers at low impact velocities and 30 vol.%SiC P /6061-T6 Al composite at shallow impact angles, Turrenne et al [17] and Ramulu et al [18] have reported that the erosive wear rates for the MMCs were less than the erosive wear rates for the Al matrix alloys when the fracture of the reinforcement was avoided.…”

The slurry erosion‐corrosion behavior of 19.5 vol.% Al18B4O33 whisker reinforced AC4C Al composite in aqueous slurry containing 3.5 wt.% NaCl and 20 wt.% silica has been investigated using a jet‐in‐slit rig. Erosion‐corrosion tests were performed with slurry having a jet velocity range 6.4 ms−1 to 15.2 ms−1 and at normal impact angle. The results indicated that the slurry erosion‐corrosion characteristics were affected by the slurry velocity and material properties. At low slurry velocities, as compared to the unreinforced alloy, the erosion‐corrosion resistance of the composite was improved because of increase in hardness as a result of whisker addition. However, steady‐state erosion‐corrosion rate was found to increase with the addition of whisker to the matrix alloy at high slurry velocities. The erosion‐corrosion rates of materials in the saline slurry were much higher than those in the water slurry even though the corrosion components were very small. It is found that the synergistic factor for the materials reduced with increasing slurry velocity although the synergism between erosion and corrosion was greater at high slurry velocity. Localized corrosion occuring in the strain‐hardened layer caused a decrease in the fracture strain of composite during erosion‐corrosion. In the saline slurry, the material removal was enhanced through cracking of flakes and detaching of whisker induced by stress and corrosion.
