Tribology, the study of friction, wear, and lubrication, is fundamental to mechanical engineering. Driven by a global demand for energy-efficient, durable, and high-performance components, the field is witnessing significant interest in novel materials, advanced surface engineering, and innovative lubrication strategies.
These advancements are crucial for reducing energy consumption, extending component lifespan, ensuring reliability, and ultimately fostering sustainability and cost-effectiveness across diverse industrial sectors.

This Research Topic aims to comprehensively address the multifaceted challenges associated with minimizing friction and wear in mechanical systems. The primary goal is to curate cutting-edge research that explores innovative materials, advanced surface modifications, and intelligent lubrication technologies capable of significantly improving the performance, durability, and reliability of components. Beyond mere performance enhancement, the focus extends to understanding fundamental wear mechanisms and developing predictive models that can guide the design of next-generation tribological systems.
