“…[45] Many studies on wear-resistant coatings focused on the development of unique structures, for example, the core-shell structure, [46] amorphous/nanocrystalline, [47] and gradient multilayer coatings. [48] A polymer coating with the core-shell structure of polymethylmethacrylate wrapped polytetrafluoroethylene shows a low friction coefficient of 0.069 and wear rate of 1.04 × 10 6 mm 3 N −1 . Voevodin et al [47] fabricated nanocrystalline WC/amorphous DLC composite coatings with a biphasic structure composed of 1 ± 3 nm sized amorphous particles and 5 ± 10 nm sized nano-crystal grains.…”

“…The residual stress of a-CN x coating can reach as high as 5 GPa after a PVD sputtering process, resulting in weak adhesion to the substrate. A Ti+C/a-CN x gradient multilayer coating with a hardness of 19 GPa was prepared by Liu et al [48] using ionbeam-assisted magnetron sputtering. The gradient layer existed between the CN x layer and the substrate.…”

There has been tremendous interest in the development of different innovative wear‐resistant materials, which can help to reduce energy losses resulted from friction and wear by ≈40% over the next 10–15 years. This paper provides a comprehensive review of the recent progress on designs, properties, and applications of wear‐resistant materials, starting with an introduction of various advanced technologies for the fabrication of wear‐resistant materials and anti‐wear structures with their wear mechanisms. Typical strategies of surface engineering and matrix strengthening for the development of wear‐resistant materials are then analyzed, focusing on the development of coatings, surface texturing, surface hardening, architecture, and the exploration of matrix compositions, microstructures, and reinforcements. Afterward, the relationship between the wear resistance of a material and its intrinsic properties including hardness, stiffness, strength, and cyclic plasticity is discussed with underlying mechanisms, such as the lattice distortion effect, bonding strength effect, grain size effect, precipitation effect, grain boundary effect, dislocation or twinning effect. A wide range of fundamental applications, specifically in aerospace components, automobile parts, wind turbines, micro‐/nano‐electromechanical systems, atomic force microscopes, and biomedical devices are highlighted. This review is concluded with prospects on challenges and future directions in this critical field.
