“…Moreover, the bonding of the coating or clad layer is directly dependent on the processing conditions. Therefore, to study the effect of processing condition, few results of flexural and adhesion strength examination from the literature 20,21,31,[71][72][73][74] were taken for the comparison purpose, as illustrated in Table 7. The results tabulated in Table 7 either are of similar kind of material system (but using some other coating/cladding technique) as of the current study or on the material system, which has already been utilized for cavitation erosion studies.…”

“…Spraying techniques are highly efficient, but they do not provide metallurgical bonding between the substrate and hard particles. 16,31 Further, because of the weak metallurgical bonding and high porosity in these coatings, they exhibit poor flexural strength (also known as the peel of strength or bonding strength) and fracture toughness (crack propagation is easy in case of coatings with high porosity). 32 The poor flexural strength and fracture toughness coating produced with spraying technique do not withstand against cavitation impact energy for an extended period.…”

Surface modification is one of the most reliable solutions for protecting the material damage in hydraulic turbines due to cavitation phenomena. However, the conventional coating/cladding process has many drawbacks like high porosity, weak adhesion strength, and poor fracture toughness. In contrast, the cladding process with microwave hybrid heating can overcome these limitations. Hence, this study aims to develop the microwave processed composite clad of Ni-based alloy with 40% Cr3C2 (by wt.) on SS-316 substrate in the domestic microwave oven of 2.45 GHz frequency and 900 W power. The selection of the material system for this study was based on mitigating the effect of cavitation erosion. The thorough metallurgical and mechanical characterization of the developed composite clad was done. Microstructural characterization using scanning electron microscopy revealed that the developed composite clads had a uniform thickness of 600 µm and free from interfacial cracks and visible pores (measured porosity ∼1.67% – as per ASTM B276). Uniformly dispersed hexagonal and stripe type carbides precipitate in the Ni-based alloy matrix of the composite clad was observed through scanning electron microscopy images. X-ray diffraction analysis shows that various hard carbides (SiC, Ni3C, Cr3Ni2SiC, Cr7C3, and NiC) and intermetallic (Ni3Fe, Ni2Si, and Cr3Si) phases were formed during microwave heating. The microhardness, flexural strength, fracture toughness of the Ni-40Cr3C2 clads were evaluated. The results reveal that the composite clad possesses microhardness = 605 ± 80 HV0.3 (∼3 times SS-316), flexural strength = 813.23 ± 16.2 MPa, and fracture toughness = 7.44 ± 0.2 MPa√m. The appropriate value of these properties makes this composite clad suitable for cavitation erosion resistance application.

“…Better tribological performance of coated steel was observed as compared to uncoated steel. Erosion rate increased with the increase of sand particle size [42]. Atmospheric plasma spray coating process was used to deposit Al 2 O 3 -40% TiO 2 on EN56B martensitic stainless steel and erosion behavior was analysed.…”

This literature study is based on the research work conducted in the field of erosion behavior of steel alloys. The focus is on the surface modification of the steel alloys by heat treatment, surface hardening and surface coating methods. Laser cladding and laser hardening processes are also explained. The influence of tribological parameters on the erosion is explained. Steel alloys are chosen because of a wide number of applications due to their excellent properties. Efforts have been made to understand the cause and the remedial action towards the improvements in wear performance. Suitable surface treatment method on the steel alloys may definitely do this work but there should be a need of proper control over the process parameters. The environmental conditions of the laboratory are differing from the real working environment. Hence, the results which are satisfactory at the laboratory are not doing well in real place of application.

“…The coating was able to reduce the mass loss by two to four times that of uncoated steel under various experimental conditions. Amarendra et al 22 deposited 70Ni-Cr coatings on SS 410 steel with plasma thermal spray process and conducted slurry erosion tests in a slurry pot tester. It was observed that 70Ni-Cr-coated steel showed better erosion resistance than uncoated steel under similar conditions.…”

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.
