“…Laser cladding, flame spraying, gas tungsten arc welding (GTAW) cladding, and plasma spraying are among the widely used surface cladding processes that can produce relatively thick cladding layers. [2][3][4][5][6] Among these processes, GTAW cladding is one of the most promising processes because of its high deposition rate and wide applicability. [6][7][8][9] This process uses a nonconsumable tungsten electrode and an inert gas for arc shielding.…”

In this study, multicomponent alloy fillers were deposited on low-carbon steel substrates using gas tungsten arc welding (GTAW) process. The microstructure and wear properties of Al-Co-Cr-Ni-Mo-Fe-Si multicomponent alloys were studied. The GTAW cladding layers were analyzed by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), X-ray energy dispersive spectroscopy (EDS), and transmission electron microscope (TEM). The results show that the microstructure mainly consisted of dendritic FeMoSi and interdendritic BCC phases and that the addition of Si coarsened the primary FeMoSi phase. In addition, different precipitate morphologies were found in the interdendrites. As the Si content increased from 5.92 to 14.53 at%, the microhardness also increased from 826 to 885 Hv and the wear resistance improved significantly. The FeMoSi dendrites possessed covalent-dominant strong atomic bonds that enhanced the hardness and wear resistance of claddings.

Surface alloying caused the improvement in the mechanical/chemical properties of near surface regions of the steels. In the present study, surface alloying treatment with boron, molybdenum, and iron on the AISI 1020 steel was realized by the technique of TIG welding. Ferrous boron, ferrous molybdenum, and Armco iron were used for surface alloying treatment. Before the treatment, ferrous alloys were ground and sieved to be smaller than 45 µm. The powders were mixed to be composed of Fe (15−x) MoxB5, where x = 1, 3, and 5 (by at.%). Prepared powders were pressed on the steel substrate and melted by TIG welding for surface alloying. Wear tests of the surface alloyed AISI 1020 steels were realized against WCCo ball using by ball-on-disk method under the loads of 2.5, 5, and 10 N at the sliding speeds of 0.1 m/s for 250 m sliding distance. Friction coecient and wear rates of the surface alloyed steel with Fe (15−x) MoxB5 alloy powder are changing between 0.30 and 0.80 and 5.86 × 10 −5 mm 3 /m to 2.52 × 10 −3 mm 3 /m depending on applied load and alloy composition, respectively.

“…Their exceptional abrasive and erosive wear resistance results primarily from their high volume fraction of hard carbides, though the toughness of the matrix also contributes to the wear resistance. The investigations of Fe-Cr-C alloy microstructures have shown that these types of materials have hypoeutectic, eutectic, and hypereutectic structures [2]. The hardfacing alloys obtained using high-energy density sources such as electron beam welding; plasma arc and laser have been widely applied to enhance the wear and corrosion resistance of material surface [3].…”
