“…Taguchi's L4 methodology was used to optimize the total number of experimental runs as Taguchi method in comparison with other methods leads to a reduction of the experiment runs in order to study the different combinations of factors and their levels resulting in quicker testing to achieve required results. 20 Table 5 shows the experimental plan along with various values of operational parameters during each experiment. The results were recorded as specific mass loss (SML), which is determined by calculating the mass loss of each specimen per unit peripheral area for each hour of testing.…”

“…Various attempts have been made in the past in the field of developing a correlation between the mass loss during the slurry erosion and influential parameters. 17,18 Many researchers [18][19][20][21] have presented empirical correlations for determining slurry erosion rate of different surfaces under the influence of various slurry related factors. Gupta et al 18 proposed the following relation to express the effect of significant parameters on the erosion rate of exposed materials…”

Various aspects such as development, experimentation, and analysis have been covered in the present work to examine the behavior of test coatings under slurry erosion. The primary objective of the present study was to establish the specific mass loss from the test coatings under various slurry environmental conditions and highlights the importance of the addition of alumina in improving the slurry erosion resistance of Ni-TiO 2 coating. To attain this objective, two powder compositions, viz. Ni-20TiO 2 and Ni-15TiO 2-5Al 2 O 3 were deposited onto the CA6NM grade hydro-turbine steel using high velocity frame spray process. The microstructural characterization of the coatings was done by employing surface roughness tester, scanning electron microscope/energy-dispersive X-ray spectroscopy, and X-ray diffraction techniques, whereas mechanical analysis was carried out using micro-hardness and bond strength tester. The slurry erosion tests were performed using an indigenously fabricated high speed slurry erosion test rig at different levels of rotational speed, average particle size of erodent, and slurry concentration in order to explore their effects on slurry erosion performance of test coatings. The slurry erosion results, as well as scanning electron microscope observations of eroded specimens, revealed higher slurry erosion resistance of Ni-15TiO 2-5Al 2 O 3 coating in comparison with Ni-20TiO 2 coating. Furthermore, each operational parameter was found to have a proportional effect on specific mass loss in case of both the coatings.

The present paper reports the analysis of wear behavior and surface properties of detonation gun-sprayed composite coating of chromium carbide–nichrome–cerium oxide (Cr3C2–NiCr–CeO2) on boron steel. Experiments were performed to have complete understanding of wear rate and volume loss for the worn out surfaces. X-ray diffraction and scanning electron microscopy analysis were used for phase detection and microstructural characterization. Addition of rare earth metal improves the stickiness and avoids corrosion in the coating. Pin on disc test rig was used for the experimental purpose, and wear rate was calculated at three loads (30 N, 60 N and 90 N) in both dry and lubricating conditions. These tests were done for different cycles (to completely understand the wear behavior). From the results, it could be concluded that in lubrication state when the applied load is less, Cr3C2–NiCr+10% CeO2 coated sample shows the better result as compared to Cr3C2–NiCr+5% CeO2 and uncoated samples.

“…They have properties like high hardness because of their pure ceramic nature. So, they were unconcerned to may erosion and corrosion environments [5] [6]. KVS Rao et al have studied the slurry erosion behaviour of plasma sprayed TiO 2 coatings on 410 steel substrate by varying the slurry rotational speed and reported that TiO 2 coated substrates possess more erosion resistance as compared to uncoated substrates [7].…”

Combined slurry and cavitation erosion resistance of surface modified SS410 stainless steel H J Amarendra, M S Pratap, S Karthik et al. Abstract. Slurry erosion is an implicit problem in many engineering industrial components such as ore carrying pipelines, slurry pumps and extruders. Even the water turbine blades are subjected to erosive wear when the water contains considerable amount of silt. In the present study, Al 2 O 3 -40%TiO 2 powder particles of average particle size of 50 micrometer were deposited on EN56B martenistic stainless steel by atmospheric plasma spray technique. Ni/Cr was pre coated to work as bond coat for good adhesion between coating and the substrate material. A coating thickness of 200 micrometer was achieved. Coated and un-coated substrates were subjected to slurry erosion test as per ASTM G-119 standard. Slurry erosion test rig was used to evaluate the erosion properties at room temperature condition by varying the spindle speed. Scanning electron microphotographs were taken before and after the slurry erosion test. Microstructures reveal uniform distribution of coating materials. Eroded surface shows lip, groove, and crater formation and dense coating resulting in less porosity. Micro hardness test was evaluated and reported. EDX analysis confirms the presence of Al, Ti and O 2 particles. It was observed that, Al 2 O 3 -40%TiO 2 coated substrates exhibit superior erosion resistance as compared to un-coated substrates due to higher hardness and less coating porosity.
