“…It is possible to use the welding technology completely without inventing new equipment and technology, and welding has unique advantages in industrial application. Wear-resistant cladding metal for carbon steel can generally be divided into Fe-based alloys, nickel-based alloys and Co-based alloys, among which Fe-based alloys are widely studied for their low cost, good wear resistance and good bonding properties [10][11][12]. The typical representative is Fe-Cr-C wear-resistant coating, which enhances the materials hardness by forming M 7 C 3 hard phase.…”

This paper aims to obtain a fine wear-resistance cladding that can be applied in guide shoe of shearer. The performance of two cladding claddings fabricated by additive manufacturing technology, no chromium-high carbon (NCrHiC) claddings and high chrome-high carbon (HiCrHiC) claddings, was analyzed through a series of characterization experiments (optical microscope, hardness, coefficient of friction, wear rate, and surface morphology). The experimental results show that the NCrHiC cladding has obvious cracks and cracks are not observed on the surface of HiCrHiC cladding. However, the hardness and wear resistance of NCrHiC cladding is better than that of HiCrHiC cladding. The microstructure of NCrHiC cladding is composed of carbides, pearlite and ledeburite, and the one of HiCrHiC cladding is M(Fe, Cr)7C3 carbides and martensite. The worn width of HiCrHiC cladding is higher than that of NCrHiC cladding. Wear mechanism of NCrHiC cladding is abrasive wear while the one of HiCrHiC cladding is adhere wear.

“…Cemented carbides, or hardmetals, are widely used for extremely demanding applications due to their hardness and strength, fracture toughness, and excellent wear resistance [4]. Another possible measures that may be taken into consideration, are the following: the whole tool quenching-and-tempering treatment, its surface carburizing, surface hardening, superficial alloying by laser or electric arc remelting, and hard surfacing [5,6,7,8,9,10,11,12,13]. According to current in-service experience, premature failures of chipper tools still remain a pertinent issue in forestry which may be a consequence of the fact that degradation behavior of forestry tools has not been up to now so widely investigated, compared to other heavy-duty tools employed in, e.g., agriculture, road building, and the mining industry [14].…”

Five different alloy hardfacings on 16MnCr5 grade low-carbon ferritic–pearlitic steel were investigated in terms of their abrasive wear resistance in laboratory testing conditions. The selected hardfacing materials, namely “E520 RB”, “RD 571”, “LNM 420FM”, “E DUR 600”, and “Weartrode 62”, were individually deposited onto plain ground-finish surfaces of 10 mm thick steel plate samples. The studied hardfacings were fabricated using several different welding methods and process parameters proposed by their industrial manufacturers. In the present comparative study, the results obtained from laboratory abrasive wear tests of the investigated hardfacings were analyzed and discussed in relation to their microstructure, hardness, and wear mechanism characteristics. Regardless of great variety in microstructure and chemical composition of individual hardfacing materials, the results clearly indicated the governing factor for the wear resistance improvement to be the overall carbon content of the used hardfacing material. Thus it has been shown that the “E520 RB” hardfacing exhibited the highest abrasive wear resistance thanks to its appropriate hardness and beneficial “ledeburite-type” eutectic microstructure.

In this study, hot strip mill vertical rolls made of AISI 4140 steel, commonly used in the iron and steel industry's hot rolling section, were coated with ER430 and E430+EC410NiMo using the submerged arc welding (SAW) method. The coatings were characterized through scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), microhardness, and wear testing (room 24 °C, 300 °C, and 600 °C). XRD analysis showed that in the ER430 sample, the dominant phase was α-ferrite phase and a small amount of γ (austenite) phase observed, while in the ER 430+EC410NiMo sample, the α-ferrite phase was the dominant phase, but the γ (austenite) phase in the structure was more severe and additionally M6C carbide phase was formed. Coating thicknesses and microhardness values of ER430 and ER430+EC410NiMo coatings were measured as 1.5 mm and 3.75 mm thicknesses, and 533±42 HV0.1 and 473±35 HV0.1 respectively. The increase in hardness on the surface of coated specimens resulted in higher wear resistance compared to the uncoated specimens under all conditions. Regarding average friction coefficient values, coated specimens generally exhibited lower values, although in some cases, the average friction coefficient was higher. In the wear tests, the lowest wear volume losses occurred in the tests conducted at 300°C, while the highest wear volume losses were observed in the tests at 600°C. Upon evaluating the wear mechanisms, it was determined that adhesive and oxidative wear mechanisms were generally dominant in the coated specimens. At higher temperatures, oxidative wear mechanisms became more prominent. ER430+EC410NiMo coatings exhibited better wear resistance compared to ER430, which can be attributed to the toughness effect of γ (austenite) and M6C phases in these coatings. Consequently, it was concluded that applying powder deposition coatings onto hot strip mill vertical rolls made of AISI 4140 steel could enhance their wear resistance, thereby increasing productivity in manufacturing processes.
