“…Currently MMC's are being explored as the candidate materials for components subjected to hard solid particle erosion. Meager information is available as regards the assessment of solid particle erosion wear of MMC's although researchers have reported on erosive wear behavior of polymer based composites [7,8]. Decrease in the angle of impact from 90˚ to 20˚ has resulted in significant increase in erosion wear loss and ductility [9].…”

Abstract. Currently, the focus in materials development is on processing of hybrid metal matrix composites (MMC's) in particular aluminum (Al) based owing to their flexibility in achieving tailor made properties. Till date, only processing, characterization of mechanical and adhesive wear behavior of various hybrid MMCs have received much attention. However, solid erosion wear of hybrid MMCs has not yet been reported. This assessment will further enlarge the range of applications of hybrid MMCs in particular for components in operation for military applications especially in desert areas. In the light of the above, the present paper discusses the air jet erosion behavior of developed Al6061-SiC-carbon fibre hybrid composite prepared by combination of powder metallurgy and casting process followed by hot extrusion at temperature of 550 o C using extrusion ratio of 1:4. The solid sand erodent particle size used was 312 µm while the operating pressure and velocity was maintained at 1.4 bar and 30 m/sec respectively. The adopted feed rate of the sand particles was 2.0 g/min with standoff distance being 10 mm. The sample size was 25 mm x 25 mm x 10 mm. The effect of silicon carbide (SiC), Carbon fibre (C f ), test duration and angle of impingement of the erodent on the erosion wear loss of the developed hybrid composite will be discussed at length.

“…The Taguchi method is applied successfully to solve the wear rate behavior of metal matrix composites [26][27][28][29][30]. Response surface methodology is used to study the dry sliding behavior of Al-7075 and Al-7075 hybrid composites [31].…”

“…Experiments were conducted according to the standard matrices of L 27 orthogonal array of the Taguchi method. The input parameters and their corresponding levels influence the specific wear rate and were selected after conducting some pilot experiments and referring past literature [26][27][28][29][30]. The input parameters and the corresponding levels were used for the present work as shown in Table 2.…”

“…The resulting surface plots were almost linear in nature and were consistently in good agreement with the obtained results of significance tests. As the load increases, the penetration ability of the fractured surface results in distinct cut marks with spalling areas that help to remove more material due to the action of pins on the surface [27][28]. Moreover, particles that were worn out and fractured due to the friction left on the contour face of the disc have greater chances of getting locked between the mating pairs, resulting in abrasion and inefficiency to decrease with an increase in sliding distance and sliding velocity [27].…”

The dry sliding wear behavior of heat-treated super duplex stainless steel AISI 2507 was examined by taking pin-on-disc type of wear-test rig. Independent parameters, namely applied load, sliding distance, and sliding speed, influence mainly the wear rate of super duplex stainless steel. The said material was heat treated to a temperature of 850°C for 1 hour followed by water quenching. The heat treatment was carried out to precipitate the secondary sigma phase formation. Experiments were conducted to study the influence of independent parameters set at three factor levels using the L 27 orthogonal array of the Taguchi experimental design on the wear rate. Statistical significance of both individual and combined factor effects was determined for specific wear rate. Surface plots were drawn to explain the behavior of independent variables on the measured wear rate. Statistically, the models were validated using the analysis of variance test. Multiple non-linear regression equations were derived for wear rate expressed as non-linear functions of independent variables. Further, the prediction accuracy of the developed regression equation was tested with the actual experiments. The independent parameters responsible for the desired minimum wear rate were determined by using the desirability function approach. The worn-out surface characteristics obtained for the minimum wear rate was examined using the scanning electron microscope. The desired smooth surface was obtained for the determined optimal condition by desirability function approach.
