“…This difference is an excellent indicator of the limited possibility of deforming in an extensive way the hypereutectic samples. Additionally, we can affirm that the massive presence of carbides for the sliding conditions selected herein was not beneficial to the performance of hardfacings, an opposite result as described elsewhere under microabrasion conditions 17 . The wear variables, especially the contact pressure and sliding velocity, were aggressive enough to promote the observed wear mechanisms.…”

“…It aims to describe the wear performance under the pin-on-disk test of hardfacings based on chromium carbides and to determine the effects of adding various carbide-forming elements (Ti, Nb, and Mo). It was done by manipulating the microstructure of hard coatings by applying the double wire deposition technique (FCDW-GTAW) [15][16][17] , and wear performance was evaluated in a pin-on-disk wear test.…”

Gas-Shielded Tungsten Arc Welding (GTAW) was modified to a Flux-Cored-Double-Wire GTAW (FCDW-GTAW); in this technique, wires of different compositions are used simultaneously to obtain different microstructures. In the modified GTAW, automatic flux-cored double-wire was used with a combination of four different wires deposited in AISI1020 steel, allowing different microstructures. Pin-on-disk wear tests described by ASTM G99 was used to evaluate the wear coefficients of four hardfacing materials combining Fe-Cr-C, Fe-Cr-C-Nb, Fe-Cr-C-Mo-Nb, and Fe-Cr-C-Mo-Ti alloys. The combination of these wires resulted in a hypoeutectic microstructure with niobium and titanium carbides, with an average hardness of 650 HV 0.3 , and hypereutectic microstructures formed by different niobium contents, with a microhardness range from 820 to 1020 HV 0.3 . The wear tests were performed without lubrication at room temperature, using a 6.0 mm diameter polished alumina sphere as a counter-body. The total distance covered was 1000 m with a speed of 0.1 m/s, a track radius of 6.0 cm, and an applied load of 10 N. Hardness, microstructure, wear coefficient, and wear mechanisms were compared. The results showed that wear resistance could be differentiated by the predominant wear mechanism: polishing for the hypoeutectic hardfacing and cracking for the hypereutectic ones.

“…The typical representative is Fe-Cr-C wear-resistant coating, which enhances the materials hardness by forming M 7 C 3 hard phase. On this basis, the wear resistance or great all-around performance were improved by adding other elements or other physical methods [2,[13][14][15][16][17].…”

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.
