“…The main factor is the soil, the cultivation of which results in abrasive wear of these working elements. It has been highlighted in the literature that abrasive wear is one of the most common tribological processes [ 4 ], and its share in the total amount of damage to machine elements is estimated at even 50% [ 5 , 6 , 7 ]. The destructive impact of abrasive wear not only concerns the working elements of agricultural tools but also is a problem in industries such as mining, construction, or mineral processing.…”

“…Currently, it is common practice to reinforce working elements by using materials characterized by higher abrasive resistance than the parent material of these elements in places particularly exposed to wear. One of the methods of improving abrasive resistance is hardfacing, the advantages of which have been confirmed in the case of cultivator coulters, plowshares, subsoiler chisels, or working elements of a rotary tiller [ 4 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. Another increasingly used method of improving the operational parameters of working elements is their reinforcing by plates made of cemented carbides.…”

Field tribological tests of two design variants of chisels used in the teeth of a cultivation-sowing unit were carried out in this research. A characteristic feature of the first variant of chisels was the reinforcement of their contact surface and almost the entire rake surface by plates made of cemented carbides. On the other hand, the second variant of chisels was reinforced only in the area of the blade by two plates made of cemented carbides, soldered on the rake face of the elements. The use of the first variant of chisels contributed to a significant reduction in the wear rate of elements, especially in terms of thickness and width loss. Effective reinforcement of the rake face, with relatively lower resistance to length reduction in the elements, raises doubts as to the validity of the use of cemented-carbide plates on almost the entire length of their rake face, because the applied variant of chisels contributed to a significantly higher price. However, the second variant of chisels effectively limited the intensity of the loss of the length of the elements, and the cause of the loss of their usefulness as part of the base material wear. It was found that the main wear mechanism of the cemented-carbide plates consisted of matrix removal under the influence of the finest fraction of the soil, which weakened the embedding of carbides, and then crushing or chipping of carbide grains from the matrix, whereas the dominant wear mechanisms of martensitic steel were grooving and micro-cutting.

“…9 The addition of various elements in iron-based hardfacing enhances wear resistance by modifying the structure of carbides. 10 The addition of vanadium during the hardfacing of steel refined the microstructure and reduced the bulk primary carbide while also increasing fine eutectic carbide content. 11 It is believed that the presence of vanadium in the Fe-Cr-C based alloy matrix results in the development of V 4 C 3 , which decreases the formation of harmful M 23 C 6 carbide and improves wear resistance and hardness.…”

Hardfacing is one of the preferred ways to prolong the life of machine components. In the current paper, efforts have been made to evaluate the flux composition on the hardness and wear behavior of a hard-faced surface. The shielded metal arc welding process was used to deposit the hardfacing layer over low carbon steel. Six different types of iron-based multicomponent flux compositions were developed using FeCr (25–30%), FeV (5%), FeMo (3–4 %), FeTi (2–3 %), Nb (3–4 %), and CeO2 (1–5 %) for hardfacing. The properties of the overlayer were examined using the microstructure study, hardness study, and abrasive wear test. Microstructural characterization was done using an optical microscope and field emission scanning electron microscope. X-ray diffraction was performed to examine the nature of precipitate formation. The worn-out surface and the debris were further examined, employing scanning electron microscopy to study the wear mechanism. The hard-faced surfaces revealed the presence of columnar and dendritic grains. Equiaxed grains were also observed in the sample, which was hard-faced with FeV. The hardness of the hard-faced surfaces was determined using the Vicker’s macro-hardness tester. A maximum hardness of 846.5 ± 2.5 HV was observed for weld overlay. The sliding wear behavior of the surface was investigated using an abrasive wear test performed on the pin-on-disk apparatus. The addition of vanadium to Fe-Cr-C hardfacing flux increased hardness and wear resistance between 3.5 and 6 times, respectively.

In the present work, two different hardfacings, namely SZ (Super-Zed alloy; C3.83Cr33.37) and ZK (Zedalloy-K; C0.65Cr4.5Mo8.18) were deposited on EN-47 ploughshare steel by manual metal arc welding process to enhance the abrasive wear resistance. In addition, the influence of heat-treatment of steel by two different methods, i.e., carburizing (C) and through-hardening (Q&T), on the abrasive wear behaviour has also been investigated. Abrasive wear studies were conducted on bare, hardfaced, and heat-treated steel in a laboratory by using a three-body dry sand rubber wheel test rig as per the ASTM G-65 standard. The bare steel suffered a high wear rate, which may be attributed to its soft ferritic-pearlitic microstructure. The abrasive wear rate of tested specimens was found to be 1.7651 × 10−3 g m−1, 0.7439 × 10−3 g m−1, 0.961 × 10−3 g m−1, 0.992 × 10−3 g m−1 and 1.21 × 10−3 g m−1 for bare, SZ, ZK, C and Q&T steel specimens respectively. The SZ hardfacing provided better abrasive wear protection than the other treatments due to high chromium and carbon concentration in the hardfacings electrodes, which presented a higher area fraction of primary M7C3 carbides in the matrix. The wear resistance indices (WRI) for SZ hardfacing, ZK hardfacing, carburized, and through-hardened steel specimens were found to be 2.37, 1.84, 1.78, and 1.46, respectively.
