“…It can be observed that at higher impingement angles the erosion behavior of Ti6Al4V is improved significantly. As stated by other researchers [28][29][30][31][32][33][34][35], ductile materials exhibit a maximum in the erosion rate at intermediate impact angles (30°). In contrast, the maximum erosion rate of a brittle material is usually obtained at higher impact angle (90°).…”

The economic and effective operation of machinery and plant involved in fluids handling is increasingly dependent on the utilization of materials that combine high corrosion resistance and good wear resistance.The present study was undertaken in order to investigate the effect of solid particle erosion on the surface characteristics, the microstructure and the aqueous corrosion behavior of a Ti6Al4V sheet metal alloy. The scope of the present effort is to examine the possible way the solid particle erosion affect, by altering the Ti6Al4V surface characteristics, the subsequent electrochemical corrosion response. As for the solid particle erosion tests, three (3) different impact angles were selected, 30°, 60° and 90° degrees respectively. Angular alumina particles of 177 -250 μm size was used as the eroding media, injected, under 1 and 2 bars pressure, on the sample surface located at 10 mm distance from the injection nozzle. The mass loss was weighted and the wear rates were calculated. Surface roughness of the eroded surfaces was assessed and the microstructural modifications were evaluated using optical microscopy and SEM-EDX.Cyclic polarization measurements were conducted in an electrolyte simulating body fluids in order to ascertain the corrosion response of the surface treated samples. SEM-EDX analysis of the corroded surfaces was used in order to assess the corrosion mechanisms and the involved phenomena and to correlate them with the surface and the overall microstructural modifications.

“…Relation between threshold kinetic energy for different operating condition and the change in erosion mechanism is discussed. JHA, et.al [11] have studied the effect of rotating speed and impinging angle for aluminum. Commercial aluminum (grade 1900) was exposed to slurry sand in water in rotary motion at various angles.…”

“…Erosion-corrosion concerns the removal of surface material by the impingement of solid erodent particles suspended in a corrosive carrier fluid. Practical examples on this context include the hydraulic transport of slurries in dredging and drilling operations, fire-fighting and cooling systems not only in naval vessels but also within oil and gas production, power generating industries and commercial shipping, such as pumps, impellers, propellers, valves, heat exchanger tubes and other fluid handling equipment [13].…”

“…Desale et al [18] investigated the effect of particle size on the erosion wear of AA6063 and reported that there is a minimum kinetic energy of the particles, which changes the mechanism of material removal from erosion to three body abrasion. Jha et al [13] studied the effects of the parameters on the erosive wear behaviour of commercial aluminium and observed that erosive wear increased with the increasing impingement angle and the rotational speed of the specimen. Gupta et al [19] studied the effect of the T6 heat treatment on the erosive-corrosive wear properties of the eutectic Al-Si alloy and concluded that the erosion-corrosion resistance of the as-cast AlSi alloy was superior to that of the conventional Al samples and that the heat treatment deteriorated the erosion resistance of the Al-Si alloy.…”

“…None of the methods is universal; however, such tests give a comparative rating of a simulated material test which is identical to the real situations [13]. From the literature survey, it is reported that the erosive rate of aluminium metal matrix composites has been reduced where the matrix alloy contained hard particles such as SiC, Al2O3, SiO2, Si3N4, glass etc.…”

In the present investigation, the erosive wear behaviour of a 10 wt.% SiC particles reinforced aluminium based metal matrix composite has been studied. The composite was fabricated by dispersing SiC particles of size 50-100 µm into the matrix alloy. The resulting material cast was characterised in terms of microstructure, hardness and erosive wear behaviour. The wear response was examined by the sample rotation technique using the slurry pot erosion tester. The effects of speed, sand content and slurry environment on the slurry wear behaviour have been studied. It was observed from the microstructural studies that the interfacial bonding strength between the aluminium matrix and the SiC particles was good and the particles were distributed uniformly. Moreover, in basic medium matrix alloy exhibited a minimum wear rate compared to the composite whereas in the case of an acidic and saline medium, an improved wear resistance was obtained in the case of the composite. The rate of material loss is found to be higher with the increased sand concentration due to the increased impinging action of the sand particles. Also, the rotational speed has a mixed effect on the wear rate. It can be concluded that the material loss was caused by the synergistic effect of corrosive, erosive and abrasive actions of the slurry medium although in the acidic medium, erosion was the dominant mode of material removal whereas corrosion was dominant in the case of a basic medium.
