“…This will lead to a lower dissipation of kinetic energy at impact and decrease the ero- sion rate. It was also noted that for particles less than 100 m, the particles might fail to rebound from the surface due to the squeeze film effect and at smaller sizes they might even fail to penetrate the squeeze film and impact the surface [7]. However, as the particles become larger, the possibility of particles rebounding and impacting incoming particles might also increase similar to the effect of increasing the sand concentration which causes the "screening" effect.…”

“…Amongst these rigs are slurry pot erosion tester [4][5][6][7][8][9], jet impingement rig [10][11][12][13][14], Coriolis erosion tester [15][16][17], pipe flow loop [18,19] and rotating cylinder apparatus [20][21][22]. Each rig has its advantages and disadvantages in terms of ease of usage, cost, ease of maintenance and control of test parameters.…”

“…The pipe flow loop provides a good indication of actual erosion-corrosion rates in slurry pipelines but is seldom used due to the high cost of construction, maintenance and actual space limitation within laboratories. A slurry pot erosion tester was selected for this work as it allows variation of parameters with good accuracy [4][5][6][7][8][9]. Erosion-corrosion testing is performed with this rig by changing the slurry medium to corrosive slurry.…”

a b s t r a c tErosion-corrosion is a complex phenomenon which involves the interaction between the mechanical processes of solid particle erosion and the electrochemical processes of corrosion. A whole range of issues is faced by a designer when trying to obtain relevant information on erosion-corrosion performance of a material. Amongst the constraints are the dispersed test conditions and test rigs available in the literature making comparisons and quantifying erosion-corrosion wear rates of different materials very difficult. The aim of this work is to evaluate the repeatability of erosion-corrosion experiments and to investigate the role of different parameters influencing erosion-corrosion. The materials tested in this work are stainless steel (SS316L/UNS S31603), carbon steel (AISI 1020/UNS G10200) and nickel-aluminium bronze (NAB/UNS C63200). A slurry pot erosion tester was used as the test apparatus and test parameters such as erodent size, erodent concentration, flow velocity and test solutions were varied to study their effect on erosion-corrosion. SEM analysis showed that a similar erosion-corrosion mechanism is seen for SS316L and NAB with formation of multiple extruded lips and platelets typically seen for erosion dominated material. In contrast the surface of AISI 1020 revealed the formation of craters, pits and shallow indentations which suggests that corrosion mechanism has a dominant influence on the material. Error rates in tests were found to have an average of 5.5% which are relatively low indicating good repeatability of test measurements and data from the test rig. The erosion-corrosion resistance of AISI 1020, SS316L and NAB were compared and it was found that SS316L showed the lowest erosion-corrosion mass loss rates in all test conditions followed by NAB and then AISI 1020. However in terms of synergistic ranking, NAB showed the best resistance to the combined action of erosion and corrosion with the highest negative synergy value. Positive synergy was evident for AISI 1020 in 3.5% NaCl and SS316L in 0.3 M HCl. A wear map is presented to evaluate erosion-corrosion trends of the materials. This work combines the assessment of test repeatability, variation in test conditions and comparison of material performance which are key stages in a material selection process.

“…To reduce erosion wear of the components, wear resistant coatings are performed by using different methods such as weld overlay diffusion 7 , thermal spray 8,9 or HVOF (high velocity oxy fuel) spray method 10 . Many parameters are effective on erosive wear rate such as liquid type, solid particle impact angle, velocity and energy, size and shape, solid particles concentration, hardness and toughness of the material [7][8][9][10][11][12][13] . Researchers have investigated the effect of different parameters on erosion wear.…”

Abstract. Composite materials are used in a wide range of applications. The erosion properties of combination of glass, jute and carbon fiber-reinforced polyester were analyzed in this study. Randomly-shaped silica (SiO 2 ) particles of various sizes (300-355μm, 355-500μm, and 500-600μm) were selected as the erosive element. Impingement angles between 15-90°, impingement velocities between 30-50 m/sec, and stand-off distances of 15-25 mm at ambient temperature were selected. During experiment, the maximum erosion of the tested composite occurred at 60° impingement angle, indicating a semi-ductile nature of the test material. Erosion increased with impact velocity and decreased with stand-off distance. In a dimensional analysis, erosion efficiency (η) and the relationship between friction and erosion were established. Test results were evaluated using Taguchi"s concept to minimize the observations needed, and ANOVA was used to identify interactions between tested parameters and to identify the most significant parameters. The S/N ratio indicates that there is only percentage of deviation between the predicted and experimental results. In further, sophisticated analyses and GMDH methods were employed, and surface damage was examined using scanning electron microscopy (SEM) to examine the nature of the wear behaviour.
