“…In hardfacing coatings, the surface of the material is coated with a material that provides high performance using a suitable welding method [12]. Various welding methods, such as shielded manual arc welding (SMAW) [13], flux cored arc welding (FCAW) [14], plasma transfer arc welding (PTA) [15], gas tungsten arc welding (GTAW) [16], and laser welding (LW) [17][18][19], are used in hardfacing applications. Although these methods have advantages and disadvantages compared to each other, the SMAW is one of the most preferred methods due to being economical and simple.…”

In this study, Fe-Mo-B-based hardfacing electrodes containing different amounts of Mo were coated on an AISI 1020 steel substrate using the electric arc welding method. The findings show that molybdenum is highly effective on the microstructure and minor changes in the coating composition affect the phases and morphological properties. In the hardness tests, an increase of 73% was achieved in the Fe14Mo2B4-based hardfacing coating, compared to the base material, and a 30% increase was achieved, compared to the Fe16B4-based coating. The highest hardness value was measured as 56.4 HRC and the highest phase hardness was measured as 3228 HV in the FeMo2B4 phase. The lowest wear rate was measured in the Fe14Mo2B4-based coating. The wear rate of the Fe14Mo2B4-based coating was 8.1 times lower than that of the substrate material and 4.7 times lower than that of the Fe16B4-based coating. According to corrosion test results, the highest corrosion resistance was obtained in the Fe16B4-based coating. The current density value of the Fe16B4-based coating was measured to be 13.6 times lower than that of the substrate material.

“…The addition of Cr and Mo to the layer compositions reduced the wear rate by up to 66% compared to the substrate. Kilinç et al [32] used TIG surface alloying to form hard layers by adding a powdered Fe-V-B mixture over SAE 1020 substrate, with a significant increase in wear resistance. In this context, PWHT treatments can be applied to optimize properties.…”

In-Situ Production of Metal Matrix Composites Layers by TIG Surface Alloying to Improve Wear Resistance of Ductile Cast Iron Using a Buffer-Layer and Post Weld Heat Treatment

et al. 2023

A TIG surface alloying process was applied to modify the surface of ductile cast iron samples. Using this process, in-situ metal matrix composite (MMC) layers were produced on samples to improve their wear resistance. These layers were made by melting substrates and powders as additional material into this melt pool. The efficiency of preheating of the samples to prevent cold cracks during solidification was verified. Moreover, a buffer layer produced in situ to decrease the mismatches between the chemical and physical properties of the materials was also tested. Post-weld heat treatment (PWHT) was used to increase the tribological characteristics of the layers and eliminate adverse effects of the heat-affected zone (HAZ) created by the fusion of the substrate surface. The results showed that, in the samples without preheating, the formation of cold cracks occurred. Additionally, layers produced without a buffer layer showed defects, such as shrinkage and porosity. However, using both preheating and a buffer layer prevented cold cracks, discontinuities, shrinkage, and porosity defects in the layers. Furthermore, PWHT allowed for the transformation of brittle martensite into tempered martensite at the HAZ. MMC layers presented high hardness of up to 1230 HV and wear resistance up to 5.8 times greater compared to the substrate samples without layers.

“…In this case, this system alloying with elements improving its plastic properties and corrosion resistance is very interesting. Modern researchers mostly focused on alloying boron-containing alloys with a chromium [78], titanium [79][80][81], aluminium [76], vanadium and molybdenum [82][83][84]. However, the formation of chromium-rich borides, such as (Fe, Cr)2B, reduces the content of corrosion-resistant alloying elements in the matrix, and therefore reduces corrosion resistance [85].…”
