“…Bayhan (2006) states that the wear rate is decreasing with the increasing ratio of carbon and manganese in the chemical composition of the edge. The results Horvat et al (2008) that they were produced from the carbon steel and the low-alloy steel. Kishore et al (2005) stated that the manganese decreases the carbide portion in the overlay layer and increases the chromium concentration.…”

“…The above mentioned presumption defines definitely the priority of the research focusing on the possibilities of the abrasive wear resistance increase. Horvat et al (2008) during the operation tests focused on reducing the wear of a mouldboard plough share by means of overlaying came to the conclusion that lower fuel consumption and higher rate of the work in ploughing compared to regular shares were achieved with hard-faced plough shares. The operation tests of the tool wear are essential.…”

Müller M., Hrabě P., 2012. Overlay materials used for increasing lifetime of machine parts working under conditions of intensive abrasion. Res. Agr. Eng., 59: 16-22.We evaluated a degree of the machine part abrasive wear with secondary focus on their hardness. The paper states laboratory results of overlay systems from their wear resistance point of view. Laboratory experiments were carried out by two-body abrasion on bonded abrasive of a P120 granularity. The results proved an increased abrasive wear resistance of martensitic, ledeburitic and stellitic overlays against eleven different original products. The overlay UTP Ledurit 60 reached the optimum values. The GD-OES (Glow Discharge Optical Emission Spectroscopy) method proved the different chemical composition of the overlay from the stated chemical composition of the overlaying electrode.

“…The relatively well-known and still-in-development methods that of improving the durability of ploughshares include pad-welding with hard alloys in the areas subjected to intensive wear. The effectiveness of this solution has been confirmed in laboratories and field research many times [14][15][16][17][18]. Research on the anti-wear properties of steels containing micro-additions of boron (e.g., steels Hardox, Raex, SSAB Boron 33) and steels surface-hardened by diffusive boriding [19][20][21] have been undertaken.…”

Tribological properties of ploughshares made of pearlitic and martensitic steels were compared in field tests. Sectional ploughshares consisting of separate share-points and trapezoidal parts were subjected to examinations. Contours of the examined parts were similar, but the thickness of the parts made of pearlitic steel was 1 to 3 mm greater for the share-points and 0.5 to 2 mm greater for the trapezoidal parts. Within the tests, sandy loams, loams, and loamy sands with circa (ca.) 13% humidity were cultivated. A greater intensity of thickness reduction and mass wear of the parts made of pearlitic steel was found, which indicates a lower resistance of this steel to wear in soil. However, contour changes of the share-points and the trapezoidal parts made of pearlitic and martensitic steels were comparable, which was probably influenced by the greater thickness of the parts made of pearlitic steel. The roughness of the rake faces of the parts made of pearlitic steel was greater than that for the parts made of martensitic steel, which can be attributed to lower hardness of the former. The largest differences occurred between maximum peak heights of the roughness profile values (R p ), which indicates stronger ridging in the case of pearlitic steel. Scanning electron microscope (SEM) observations of the rake faces showed that martensitic steel was subjected to wear mostly by microcutting, but pearlitic steel was principally worn by microcutting and microploughing. During tillage, only one share-point made of pearlitic steel was broken. However, the main disadvantage of these parts was that their bending was related to the lower mechanical strength of pearlitic steel.

“…High chromium hardfacing was widely used in mining, minerals industry and agriculture because of their excellent abrasion resistance (Chotěborský et al 2008;Horvat et al 2008;Brožek et al 2010). Microstructure of high chromium hardfacing after weld depositing consists of hypoeutectic, eutectic or hypereutectic microstructure (Atamert, Bhadeshia 1990).…”

Chotěborský R., 2012. Effect of heat treatment on the microstructure, hardness and abrasive wear resistance of high chromium hardfacing. Res. Agr. Eng., 59: 23-28.The effect of destabilization heat treatment on the microstructure, hardness, fracture toughness and abrasive wear resistance of high chromium hardfacing was investigated. The results from the study shows that the hardness, fracture toughness and abrasive wear resistance are influenced by temperature of destabilization heat treatment and air and furnace cooling conditions, respectively. Destabilization treatment of materials by furnace cooling caused higher secondary carbides in the dendritic austenite whilst by air cooling it showed smaller particles of secondary carbide. Also, it was found that destabilization temperature at 1,000°C improves hardness compared with hardfacing after weld depositing. The study, however, indicated that Palmqvist fracture toughness method is a useful technique for measuring the fracture toughness of high chromium hardfacing compared to Vicker's hardness method.
