“…In this case, many particles of abrasive sand on the GRP surface produced a repeate plastic deformation; this in turn led to fatigue cracking and hence crack coalescence, an the fatigue cracks spread and interlaced with each other over time. Therefore, the surfac was worn and torn [51]. The failure modes for 2 h of corrosion for 250 g, 400 g and 500 g of sand are shown in Figure 8(1-a-1-c).…”

Glass-fiber-reinforced pipe (GRP) is a strong alternative to many other materials, such as cast iron and concrete. It is characterized by high corrosion resistance, resulting in good erosion/corrosion. For the erosion/corrosion test, commercially available GRPs were used, which are frequently utilized for oil field wastewater in harsh environments. This type of GRP material was subjected to simulated conditions replicating in situ or harsh environments. An extensive experiment was conducted. Three quantities of abrasive sand (250 g, 400 g and 500 g with a size of 65 µm) were mixed with 0.015 m3 of water. The abrasive sand samples were taken at a 90 degree angle from the wall of the cylinder tubes. Three flow rate conditions were selected, 0.01 m3/min, 0.0067 m3/min and 0.01 m3/min, with 10 wt.% chlorine. Furthermore, these tests were conducted at five different times: 1 h, 2 h, 3 h, 4 h and 5 h. The results show that the erosion rate increased both with an increasing amount of abrasive sand and with increasing flow rate. The maximum value for the erosion rate was more than three for a flow rate of 0.015 m3 with chlorine for 500 g of sand. The corrosion rate also showed the same trend, with the maximum corrosion rate being reached under the same conditions. It was found that the corrosion rate largely depends on the amount of weight loss, which is an indicator of the erosion effect. Therefore, GFRP provides better erosion/corrosion resistance in a harsh environment or in situ conditions.

“…Grewal et al 5 suggested that at 90 • impact angle, maximum mass removals take place due to the formation of deep craters and platelet mechanism, and at 60 • impact angle, plowing might be the reason of minimum mass removal rate, as the impact energy of the particles would make the material to deform plastically. Wen 37 analyzed that erosion at high impact angle occurs due to chip formation, spalling and plastic deformation, whereas erosion at low impact angle occurs due to cracks and pit formation. The erosion rate of all the samples increases with the increase in the level of slurry concentration.…”

The aim of the present study is to investigate the slurry erosion behavior of nanoyttria-stabilized zirconia (YSZ) reinforced Cr 3 C 2 -25NiCr ceramic nanocomposite coatings deposited on turbine steel. The Cr 3 C 2 -25NiCr coating powder, 95% (Cr 3 C 2 -25NiCr) + 5% YSZ, and 90% (Cr 3 C 2 -25NiCr) + 10% YSZ nanocomposite coating powder deposited on CA6NM steel samples by using high-velocity oxy-fuel coating technique. L 9 orthogonal array Taguchi method was used to design the experiment. Erosion tests were performed on erosion test rig under hydro accelerated conditions at different levels of various parameters. Erosion tests and analysis of variance resulted that for coated samples, velocity is the major influencing factor followed by slurry concentration, impact angle, and particle size. Velocity was the largest contributor to the mass loss, whereas particle size has the least contribution to mass loss of the coated samples. The scanning electron microscopy analysis of eroded samples revealed that craters, micropores, platelets, plowing, spalling, and so on were responsible for the mass loss of uncoated and coated samples. The incorporation of YSZ nanoparticles decreased the porosity; erodent particles cannot penetrate more deeply inside the workpiece and resulted in less erosion. It has been resulted that 95% (Cr 3 C 2 -25NiCr) + 5% YSZ and 90% (Cr 3 C 2 -25NiCr) + 10% YSZ ceramic nanocomposite coatings exhibited better erosion resistance as compared to Cr 3 C 2 -25NiCr coatings due to high microhardness and low porosity.

“…Grewal et al [2] suggested that at 90˚ impact angle, platelet mechanism and formation of deep craters play a major role to maximise the mass removal rate, and at 60˚ impact angle, ploughing might be the reason of minimum mass removal rate, as the impact energy of the particles would make the material to deform plastically. Wen [38] observed that erosion at high impact angle occurs due to formation of pits and plastic deformation fatigue spalling, whereas erosion at low impact angle occurs due to formation of pits, cracks and cutting. The increase in level of slurry concentration has led to increase in erosion rate of all the samples.…”

Slurry erosion behaviour of HVOF (High Velocity Oxy Fuel) and plasma sprayed coatings on CA6NM hydraulic turbine steel has been investigated at different levels of various parameters. The Cr 2 O 3 -50%Al 2 O 3 composite powder was prepared and deposited on CA6NM steel samples to get the uniform thickness coatings. The surface roughness, porosity and microhardness of as-coated samples were measured. The as-coated samples were subjected to SEM/EDS analysis to evaluate the surface microstructure of the developed coatings. Erosion tests were performed on self made erosion test rig under hydro accelerated conditions. The study reveals that the velocity, impact angle and slurry concentration were the most significant parameters, influencing the erosion rate of these coatings. The average particle size had least affect on the erosion rate. HVOF-coated samples showed better corrosion resistance as compared to plasmacoated samples due to high hardness of HVOF-coated CA6NM samples.
