Lubricants, Journal Year: 2025, Volume and Issue: 13(3), P. 112 - 112

Published: March 5, 2025

Additive manufacturing technology has the advantages of precise manufacturing, high levels customization, and large-scale molding; it can achieve design complex geometric structures structural/functional integrated components, which is difficult to realize using traditional technology, especially for different tribological applications. Ceramic materials are widely used in industries such as high-end aviation, aerospace, energy, biomedicine due their excellent wear resistance, temperature stability, hardness. The properties ceramic parts determine versatility durability during application process. rise additive field ceramics opened up possibility creating with friction overcoming limitations processes. Although several studies on 3D printing wear-resistant/self-lubricating metal- or polymer-based have been published, there until now no comprehensive review advanced structural composites purpose reducing enhancing wear-resistant properties. This article discusses currently processes, tribology, how combination these two improve components from perspective micro- macrostructures. Finally, specific applications additively manufactured various industrial biomedical fields also introduced.
