“…In the wear process, micro-cutting on the metal matrix between the particles happens under repeated action of abrasion. With the cyclic effects of mechanical stress and thermal stress, microcracks generate along defects or grain boundaries (Rathod et al , 2019; Shao et al , 2021). Then the cracks from different directions are merged to form delaminated craters.…”

“…During sliding, the cracks cannot propagate in the direction parallel to sliding surface because the cracks cannot easily pass through melt pool boundaries and hard phases, reducing the tendency of delamination (Rathod et al , 2019). In addition, the existence of tribolayer acted as hydrodynamic lubrication can reduce frictional force between the counter surfaces (Shao et al , 2021). The smeared debris distributed on the worn surface contributes to third-body abrasion and experiences heterogeneous deformation which can prevent serious plowing of the worn surface (Yan et al , 2019b).…”

Purpose Laser powder bed fusion (LPBF) can be used to fabricate complex extrusion die without the limitation of structures. Layer-by-layer processing leads to differences in microstructures and wear properties. This study aims to investigate the microstructure evolution and effects of tungsten carbide (WC) on the wear properties of LPBF-printed 18Ni300. Design/methodology/approach Economical spherical granulation-sintering-deoxygenation (GSD) WC-reinforced 18Ni300 steel matrix composites were produced by LPBF from powder mixtures of WC and 18Ni300. The effects of WC contents on anisotropic microstructures and wear properties of the composites were investigated. Findings The relative density is more than 99% for all the composites except 25% WC/18Ni300 composite. The grain sizes distributed on the top cross-section are smaller than those on the side cross-section. After adding WC particles, more high-angle grain boundaries and larger Schmid factor generate, and deformed grains decrease. With increasing WC contents, the hardness first decreases and then increases but the wear volume loss decreases. The side cross-section of the composite has higher hardness and better wear resistance. The 18Ni300 exhibits adhesive wear accompanying with abrasive wear, while plowing and fatigue wear are the predominant wear mechanisms of the composites. Originality/value Economical spherical GSD WC particles can be used to improve the wear resistance. The novel WC/18Ni300 composites are suitable for the application under the abrasive wear condition with low stress.

“…Thin-film coatings provide an inexpensive yet effective means of protecting a wide range of industrial components and processing tools. They have thus attracted significant research attention in recent decades [1][2][3][4][5][6]. Transition metal carbide coatings are of particular interest due to their many outstanding properties, such as hardness, high wear resistance, good thermal stability, and superior chemical stability.…”

CrC and NbC carbide coatings both have good mechanical properties, wear resistance, and corrosion resistance. The present study seeks to combine the two coating systems in order to further enhance their properties. NbCrCx and NbCrCxNy coatings (where x and y denote the atomic percentages of carbon and nitrogen, respectively) were deposited on SKH51 substrates using a radio-frequency unbalanced magnetron sputtering system. The mechanical, tribological, and corrosive properties of the coatings were investigated and compared. Among the NbCrCx coatings, the NbCrC61 coating showed high levels of hardness, excellent adhesion strength, and good wear resistance. Among the NbCrCxNy coatings, the NbCrC55N5 coating showed high adhesion strength and hardness and excellent tribological properties. However, for nitrogen contents greater than 16 at%, the adhesion strength was dramatically reduced, resulting in poor tribological performance. Among all of the coatings, the NbCrC49 coating showed the best corrosion resistance due to its enhanced crystallinity, high adhesion strength, moderate surface roughness, and high sp3 C-C bonding ratio.
