“…Apart from the equipment loss, there are indirect costs associated with downtime of wear-related failures. For applications that are subject to extreme wear conditions as in oil sands and natural gas extraction, companies tend to protect equipment using sintered tiles, owing to their high hardness [1], wear resistance [2][3][4][5], and relatively better strength [6]. Carbide, such as WC, particles, typically between 1 to 5 μm in size, held together by a cobalt (Co) or nickel (Ni) matrix alloy, form such sintered tiles.…”

Surface mining causes significant wear damage that affects equipment performance, reliability, and lead to associated downtime costs. To improve the wear resistance of components used in natural resources industries, cemented carbide tiles are joined to engaging surfaces of the components. Joining of cemented carbide to structural steel can be achieved by various processes, among which brazing is commonly used owing to its relatively simple processing and low cost. A significant challenge in brazing cemented carbide tiles to steels is the poor joint strength. This article aims to review the recent progress in improving joint strength of cemented carbide/steel brazing. Recent progress on the key factors, including type of filler metals, evolution of joint microstructure, generation of residual stresses, and process parameters have been closely examined and critically analysed. Future directions of research on brazing cemented carbide tiles to steel in order to improve joint strength have been proposed.

Wear is a major issue in industry, particularly with metal components. Therefore, it is crucial to investigate methods that offer increased resistance to this phenomenon. In this research, three coating systems (pure WC-CoCr and WC-CoCr/NiCrFeSiBC+Mo, 88:12 and 83:17 wt.%) were thermally sprayed on an AISI 1018 steel substrate through the High-Velocity Oxygen Fuel (HVOF) process. The coatings were characterized using a field emission scanning electron microscope (FESEM) equipped with the energy dispersive spectroscope (EDS) and X-ray diffractometry (XRD). An analysis of the wear rate for ball-on-flat linear reciprocating sliding tribological tests for the coatings was also carried out. The coating microstructure presents well-dispersed NiCrFeSiBC splats. The WC-CoCr/NiCrFeSiBC+Mo, 88:12, system has the highest wear resistance, decreasing by 30.2% at high loads compared to commercial WC-CoCr CERMETs, and also exhibits the highest fracture toughness. Analysis of wear tracks shows that the material removal at all charges occurred mainly by an abrasive wear mechanism.
