“…However, they cannot sufficiently increase the performance of high-tech, high-capacity cultivation implements. In particular, in order to extend the economic life of cultivator blades and achieve high productivity, [5][6][7] scientists have investigated different practical techniques such as carburizing, nitriding, carbonitizing, 8,9 and boriding. 10 Scientists have from time to time also used various surface quality improvement techniques such as thermal spray coating, surface hardening, electrodeposition, melting of flux-cored wires and others.…”

The poor abrasive wear behavior of agricultural machinery affects the farmers all over the world, rendering their activities more inefficient and negatively affecting their productivity. Therefore, innovation in the manufacture of soil cultivation machinery and the selection of wear-resistant materials has been of great importance. Recently, boron alloys, in particular, have been used in the manufacture of machinery parts that work the soil. The aim of this was to investigate the behavior of the blades of the machines widely used in soil cultivation in agricultural production following a surface treatment technique. For this purpose, the blades made of 30MnB5, a material widely used in the production of cultivator blades, were used as substrate samples in the trials as well as blades of the same substrate coated with Fe28Cr5C1Mn alloy wire via the electric arc spray technique. The morphologies and structures of the uncoated and coated samples were comprehensively analyzed by light microscopy, scanning electron microscopy, energy dispersive spectrometry and X-ray diffraction. In addition, their microhardness, porosity, and surface roughness properties were assessed separately before and after plowing. These prepared blades were tested under in the same conditions by plowing the same field at two different soil moisture. Although the weight loss was measured as 9.4 g and 5.4 g in the uncoated and in the coated sample at 9% moisture level, respectively, the weight losses were at 14% humidity level were 10.6 g and 5.9 g in the uncoated and coated samples, respectively. Although the amount of wear increased with increasing humidity levels in both groups, the mass wear loss in cultivator blades coated with Fe25Cr5C1Mn alloy wire was found to be lower in all trials. The results suggest that coating the cultivator blades using electric arc spray would increase agricultural productivity and reduce factors that cause environmental pollution.

“…Poor abrasive wear behavior makes farmers less efficient and plays a major role in raising the cost of agriculture [2] by adversely affecting farmers' productivity, thereby making the whole process of agriculture economically unviable. Scientists and researchers have applied different techniques such as coatings [3][4][5][6][7][8][9][10][11][12][13][14], carburizing [15], nitriding and carbonitriding [15], boriding [15][16][17][18][19][20], and shot peening [21] to enhance the working life of rotavator blades. These techniques have shown promising results with regard to improving wear resistance in the short term, but limited data related to the long term success of these techniques is reported in the published work.…”

Rotavator blades are prone to significant wear because of the abrasive nature of sand particles. The aim of this research work is to investigate the effect of cryogenic treatment and post tempering on abrasive wear behavior, in the presence of angular quartz sand (grain size of 212–425 μm), of rotavator blade material of boron steel (30MnCrB4). Cryogenic treatment has caused an improvement in the abrasive wear resistance and microhardness of 30MnCrB4 by 60% and 260.73%, respectively, compared to untreated material due to enhancement in hardness, the conversion of retained austenite into martensite, and the precipitation of secondary carbides in boron steel after exposure to cryogenic temperature. Economic analysis justifies the additional cost of cryogenic treatment.

“…In this contemporary era, there is a plethora of manufacturing units that are facing the problem of erosive wear. Owing to the influence of abrasive along with hard particles employed in the components, which are utilised in hydro machinery causing erosion, the reduction of the efficiency of turbine frequently occurs, which ultimately halts whole working operations [1][2]. There are myriad factors, for instance, the size and hardness of erodent particles, level of slurry concentration, the impact velocity of abrasive particles as well as the target surface characteristics that influence the erosive wear of elements utilised in hydro machinery [3][4][5][6][7].…”

Myriad hydro materials have been encountered with the severe attacks of eroded particles during the operation, leading to degradation of target material and economic loss. In this study, Colmonoy-6+WC powders were deposited with the help of the laser cladding method on the bare SS304 and SS410 steel surfaces. Distinct properties of cladded surfaces, such as mechanical as well as metallurgical properties, were investigated. The influence of slurry erosion parameters like angle of impact and impact velocity of eroded particles on the cladded as well as uncladded steel specimen was analysed. Under all slurry erosion conditions, there was an escalation in slurry erosion resistance in the case of cladded steel as that of as-received steel specimens. In slurry erosion, the influence of the impact velocity of erodent particles is more against the impact angle. The scanning electron microscopy images of eroded uncoated steel specimens represent ductile behaviour along with the formation lip, ploughing etc., while eroded cladded steels exhibit brittle behaviour.
