AA6082-T6 aluminum alloys are widely used in various applications in automotive and aircraft industries. They offer an attractive combination of surface properties, strength and corrosion resistance. The structural components manufactured by AA6082-T6 aluminum alloys can be exposed to impingement of solid particles throughout their service life. In this study, erosive wear behaviors of AA6082-T6 aluminum alloy were investigated. For the evaluation of erosive wear induced by solid particle impacts, a detailed study was conducted on AA6082-T6 aluminum alloy by using aluminum oxide (Al2O3) erodent particles. Two different particles were used in solid particle erosion tests, which are 60 mesh (212–300 µm) and 120 mesh (90–125 µm), respectively. Also, the aluminum alloy samples were tested under two different air pressures (1.5 bar and 3 bar). The erosive wear tests were carried out according to ASTM G76 standard at six various impact angles (15°, 30°, 45°, 60°, 75°, 90°). The surface roughness and morphology of worn samples were analyzed by using a non-contact laser profilometer. It was found that erodent particle size affected the surface erosion damage, erosion rate, crater morphology and roughness. The eroded surfaces of specimens were analyzed by SEM. The surfaces of specimens were also investigated by using EDS in SEM studies.

The present work is aimed at investigating the effect of speed , slurry concentration and particle size on Inconel-718 coatings on copper subjected to slurry erosion with the help of DOE (design of experiments) tool among which the Taguchi technique is well known. The coatings are subjected to slurry erosive wear tests in 3.5% NaCl solution (35 gms NaCl/ ltr of water) with sand as erodent. On application of analysis of variance, it is found that all three parameters namely speed, sand concentration of the slurry and particle size are significant with speed being the most significant one.

In this article, micro and nano titania ( TiO2 ) filled A384 alloy composites are fabricated by stir casting technique with varying filler content from 0–8 wt.% respectively and then we study their physical, mechanical, thermal and erosive wear characteristics respectively. Effect of impact velocity (25–70 m/sec) and impingement angle (30°–90°) on erosion wear behavior of micro and nano TiO2 filled A384 alloy has also been studied. Finally, an optimization technique was implemented in order to develop a correlation between the physical, mechanical and erosion rate of TiO2 filled A384 alloy composites by using technique order preference by similarity to ideal solution (TOPSIS).

Solid particle erosion behavior of non-conventional thermal barrier coatings prepared by dip coating of sol–gel 7[Formula: see text]wt.% yttria-stabilized zirconia (7YSZ) has been studied in the present paper. The purpose was to show its applicability to protect aeronautic bodies vulnerable under solid particle impact, e.g. the leading edges of the wings, the radome or the leading edges of rotor blades. The effect of operational variables on erosion rate is studied both for uncoated AA2024-T351 substrate and sol–gel-derived 7YSZ top-coat on AA2024-T351 substrate. The interactive influence of variables on erosive wear behavior is also systematically studied using an air-jet erosion tester under four different parameters such as temperature (25, 150, 275 and [Formula: see text]C), impact angle ([Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]), impact particle velocity (40, 60, 80 and 100[Formula: see text]m/s) and erodent flow rate (2, 3, 4 and 5[Formula: see text]g/min) using L[Formula: see text] Taguchi design of experiments. The optimal experimental parameters were obtained by orthogonal arrays, signal-to-noise ratio (SNR) and analysis of variance (ANOVA) for uncoated and coated aluminum alloys AA2024-T351. The temperature was found to be the most influencing parameter followed by impact angle, impact velocity and erodent flow rate for uncoated samples. For 7YSZ sol–gel coated samples, temperature was the most influencing parameter followed by impact angle, erodent flow rate and impact velocity.

Abstract Two grades of stainless steel, 316 and 440-C, in the form of solid wire, and two cored wires, Duocor and 95-MXC, were used. Coatings were made using the Miller BP-400 and TAFA 9000 systems. Slurry jet erosion tests were conducted using a 10 %w/w alumina particle/water slurry. Two alumina particle sizes, 320 and 80 grit (nominal grain diameters 35 μm and 200 μm, respectively) were used at impinging angles of 90° and 20°. The nominal impact velocity of the slurry was 15 m/s and the nozzle-specimen distance 100 mm. The volume loss of material under various slurry erosion conditions was related to the coating properties and microstructure. Results indicate that the wear behavior of arc sprayed materials is dependent on the erodent particle size; for large erodent particle size, the relative erosion is almost independent of the impinging angle, while for the smaller particle size the angle effect is the dominant factor. This behavior can be related to the lamella structure and the relative toughness of the different phases of the coatings.

Wear Property

Al2O3-glaze composite ceramic coating was prepared with enamel coating as transition layer and Al2O3 as hard antiwear facies on Q235A steel surface in this paper, and the effects of the particle size and volume fraction of ceramic coating on erosive wear behavior of composite coating were investigated. The results show that enamel performance of ceramic coating is better when the particle size of glaze is 16µm; the anti-wear property of composite ceramic coating is improved by adding Al2O3 particle, and the coating with 50μm particle size and 40% volume fraction particles, eroded at 45° impact angle at 15MPa pressure, is the best, which is 4.2 times than that of the enamel coating without Al2O3.

And Diffusion

To the description of changes of solid particle size in population, the application was proposed of stochastic differential equations and diffusion equations adequate to them making it possible to express the development of these populations in time. Particular relations were derived for some particle size distributions in flow and batch equipments. It was shown that it is expedient to complement the population balances often used for the description of granular systems by a "diffusion" term making it possible to express the effects of random influences in the growth process and/or particle diminution.
