“…A lot of research work has been carried out on aluminum based composite materials reinforced with silica (Surappa) [8] at varying volume fractions for altering mechanical, physical, thermal and tribological properties. The significant benefits in the form of performance and economics triggered the research in the area of AMC's and are still carried on [9][10][11]. Researchers are focusing on many influencing parameters to obtain the desired properties by altering the processing routes, reinforcement types, volume fractions, alloying, heat treatment method, etc.…”

Aluminium metal matrix composites are widely used in aerospace and automotive industries owing to favorable properties of low weight and functionally graded properties obtained by incorporating different reinforcements. The present work is based on the analysis of dry sliding wear behavior and parametric optimization of aluminium composite reinforced with alumina, graphite and B 4 C particles using Taguchi technique. Specimens were prepared via stir casting process and optimal percentages of reinforcements were determined by Vickers microhardness tests. A L9 orthogonal array was selected and analysis of variance was used to investigate the influence of wear parameters involving normal load, track diameter and sliding distance on dry sliding wear of the developed composites. All the three selected parameters were varied at three levels. The results revealed that lower values of Graphite (3%) and boron carbide (1%) in combination with higher values (10%) of alumina as reinforcements contributed to the higher Vickers micro hardness. ANOVA revealed that p-value for normal load was 0.006 and was the most significant factor in the weight loss with a 65.05 % contribution. Further, Downloaded by [University of Nebraska, Lincoln] at 20:32 11 April 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 confirmatory tests were carried out to validate the optimized results and results obtained with optimum parameters were within ±5%.

“…4 (a-c). At 30° impact angle, maximum erosion occurrence takes place due to maximum cutting velocity component than the deformation velocity leading to ploughing and scattering of the particles [8,15]. The surface topography/morphologies at 60° impact angle were shown in Fig.…”

“…The harsh ploughing marks were also largely observed on the wear surfaces of the sample. The different type of material removal mechanisms like large pile-up or ploughing, crates, leading to the formation of platelet (flake), cutting action, lip fragmentation and indentations are responsible in solid particle erosion of SS 304 [8,15,[23][24][25]. The material removal mechanism mostly depends on the sample surface properties and the impact angle of a solid particle on the surface of wear substrate [24].…”

“…It has been found that no such significant improvement was observed in hardness and strength with respect to fiber loading. Sahoo, et al [15,16] investigated the effect of microstructure variations and volume fractions of primary alpha phase along with significant parameter of erosion wear on Ti-6Al-4V alloy using air jet erosion test rig. They observed impact velocity as the most significant parameter than microstructure variation.…”

“…Erosion-corrosion-related problems occur in power plants, oil and gas processing, and chemical plants where there is an interaction between solid particles, corrosive fluid, and a target material [2][3][4][5]. The interactions between erosion and corrosion are complex and both processes can either complement each other and accelerate the material removal rate or may suppress the total wear rate [6,7].…”

Synergistic Erosion and Corrosion Behavior of AA5052 Aluminum Alloy in 3.5 wt% NaCl Solution Under Various Impingement Angles

Erosion-corrosion behavior of AA5052 aluminum alloy was studied in 3.5 wt% NaCl solution containing silica sand as erodent particle. The tests were carried out according to ASTM G119-09 standard using a slurry jet apparatus at a jet velocity of 3 m/s, sand concentration of 90 g/l, and various impingement angles of 25°-90°. The pure erosion rates were also obtained using cathodic protection of the samples during erosion-corrosion tests. Results showed that maximum pure erosion and erosion-corrosion rates occurred at impingement angle of 30°. On the other hand, a negative synergism rate was obtained under all conditions tested. Energy dispersive spectrometry analysis suggested that the negative synergism could be attributed to the existence of a protective oxide layer formed on the eroded surface of the samples during erosion-corrosion tests. Results also showed that corrosion rates during flow corrosion (i.e., no sand) and erosion-corrosion were much higher than the pure corrosion rate in a stagnant condition. Furthermore, there almost was no change in the corrosion rates at various impingement angles of 25°-90°. Scanning electron micrographs showed erosion features like raised lips and wear tracks at the impingement angle of 30°, and plastic deformation due to particle impact at the impingement angle of 90°.
