Microstructure and abrasive wear characteristics of in situ vanadium carbide particulate-reinforced iron matrix composites

Heterogeneous nuclei effect of MgAl2O4 on NbC in Fe matrix MMC coating

“…From Fig. 9(b), broken primary NbC carbides can be observed in M-1 coating, and the broken carbides are considered as reinforcements to block the abrasion paths [3,36,37], which is beneficial to decrease the wear loss of the coating.…”

“…Niobium carbide (NbC) reinforced Fe-based composite coatings have been widely applied for surface strengthening of iron-based materials due to their high hardness, excellent wear resistance and price advantage [1,2]. It is generally believed that the main factors affecting the wear resistance of carbide-reinforced composite coatings are the hardness, size, distribution and morphology of carbides [3,4]. In order to meet the ever-increasing demand for harsh working conditions, it is necessary to find some ideas to further improve the wear resistance of the coating.…”

Multi-material additive manufacturing of low sintering temperature Bi2Mo2O9ceramics with Ag floating electrodes by selective laser burnout

“…Fabrication of Ti-Al 2 O 3 compositionally graded structures to evaluate the capability of making a metalceramic composite via laser AM has also been successfully demonstrated (Zhang and Bandyopadhyay 2018). Overall, AM of metals and ceramics has been an area of interest as it allows manufacturing of components with outstanding properties compared to conventional alloys (Man et al 2001;Pang, Man, and Yue 2005;Nurminen, Näkki, and Vuoristo 2009;Balla, Bose, and Bandyopadhyay 2010;Zheng, Chen, and Lian 2010;Das et al 2011;Zhong et al 2014;Zhang, Sahasrabudhe, and Bandyopadhyay 2015;Sahasrabudhe and Bandyopadhyay 2016). However, fitting metals and ceramics into one component using AM is still at the early stages of investigation to overcome the current limitations such as sintering/ melting temperature mismatch, dimensional accuracy and chemical compatibility of different materials to make functional components for practical systems.…”

Discovering novel VC1− compounds through hybrid first-principles and evolutionary algorithms

“…The most common use of vanadium carbide is to be utilized as an reinforcement to improve mechanical strength of steel and coatings [16][17][18][19]. However, we should note that vanadium carbide has potential to be used for the design of UHTCMCs.…”
