“…These techniques largely improve a very thin layer of surface material, and chipping off this layer leads to severe wear. Therefore, there is need to explore material processing techniques for improving the abrasive wear resistance of rotavator blade material [22][23][24][25].…”

Abrasive Wear Behavior of Cryogenically Treated Boron Steel (30MnCrB4) Used for Rotavator Blades

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.

“…Researchers are striving hard to improve the life of tillage tools by applying various surface modification techniques [16,[19][20][21][22]. Wear resistance of tillage tools can be enhanced by Quenching and Tempering (Q&T) [10,23], Carburizing [24,25], Boriding [26,27], Carbo-Nitriding [28,29], Nitriding [30,31], cryogenics [32,33], Weld overlying [34][35][36], Coatings [37,38] and Laser hardening [39,40].…”

“…Yazici [28] investigated the wear behaviour of carbonitrided 30MnB5 steel ploughshare blades and reported that the time, temperature, and atmospheric conditions of the carbonitriding process affect the microstructural and mechanical properties of ploughshare blades. The ploughshare blades carbonitrided at 860 °C for 105 min exhibited higher wear resistance and found a 14.65% reduction in total weight loss.…”

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.

“…The mass wear decreased by 14.65% and the dimension by 26.47%. According to the results the carbonitridation seems to be the effective solution to decrease the wear (Yazici 2011).…”

“…Another possible solution of the problem is a chemical heat processing of the high-quality carbon steel. Yazici (2011) dealt with the increase of the wear resistance by means of the carbonitridation in his research. Mass and dimension losses were essentially lower at the field tests compared with the conventionally heat-treated ploughshares.…”

Hrabě P., Müller M., Hadač V. (2015): Evaluation of techniques for ploughshare lifetime increase. Res. Agr. Eng., 61: 72-79.Sustainability in a sphere of agricultural commodities production depends on soil processing. The soil is also a considerable abrasive medium which affects in a negative way tools processing the soil. The aim of the research is to increase the lifetime of a mould board by means of a constructional setting of an overlaid material. The lifetime increasing of the ploughshare by means of the overlaying is a much discussed topic. For this reason such strategy for the experiment was chosen which would enable to increase the lifetime at preserving low costs for ploughshare treatment. The research was focused on the ploughshare lifetime increasing by means of overlaying the abrasive wear with resistant material. The ploughshares of one of the leading world producers of the soil processing machines were chosen for the experiment. The aim of the work is to compare two commonly available overlaid materials in the combination with two overlaying techniques.
