Interface science and engineering for less friction and wear
Friction is the resistance against motion. It is an obvious phenomenon whenever a solid body moves over another. At the interface of moving surfaces, solid–solid and solid–fluid interactions take place and generate frictional heat. This frictional heat not only changes the physical and chemical nature of the interacting surfaces but also their topography. The wear and energy loss are the derivatives of friction. This wear is the main cause of concern for leading maintenance and repair issues involving various machine components like brakes, clutches, gear boxes and so on. Thus, the reduction of friction and wear is essential in enhancing service life and lowering expenditure, which could potentially lead to significant operational cost reduction. Therefore, the study of interface phenomenon and surface characteristics is crucial in obtaining a better and stronger performance from every moving element. Recent technological advancements enable us to explore these interface phenomena and surface properties within various domains, ranging from the atomic and molecular to the micro- and nano-scale. This micro-/nano-scale level of understanding bridges the gap between science and engineering methods, in addition to furnishing the knowledge required for the optimal design of various materials and components for technological applications. Interface science and engineering thereby play a pivotal role in every facet of daily life, spanning from live cell friction to engine lubrication. The central theme of this special issue is geared towards tailoring surface and interface elements to reduce friction and wear and consequently obtain better moving surfaces. The main goal of this special issue
