Abstract
A new surface-texturing technique—laser-induced cavitation micro-texturing (LICMT) was proposed to improve the friction and lubrication properties of 7050 aluminum alloy. Reciprocating friction tests were used to analyze the tribological properties at different micro-texturing densities and depths under starved lubrication conditions. SEM was used to observe the morphology of the wear surface. The average friction coefficient and wear rate were lowest for a micro-texturing density of 19.63 %. The average friction coefficient decreased with increasing micro-texturing depth. Compared with LST, no craters formed on the surface. Because of the lower abrasive and adhesive wear, the LICMT samples exhibited good friction reduction and lubrication performance. Finally, the mechanism of LICMT explained friction reduction and lubrication under starved lubrication conditions.
期刊介绍：
Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry.
The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
