Abstract

Metals are among the most important engineering materials, playing irreplaceable roles in modern society. Traditionally, metal research has focused on the effects of composition and microstructure on the physical and mechanical properties of metals. More recently, the effects of surface micro- and nanostructures on the application performances of metals have increasingly been reported. These studies are inspired by natural phenomena such as the self-cleaning effect of lotus leaves. Because large-area microscale and nanoscale surface structures are difficult to prepare using traditional materials-processing technologies, they are commonly introduced by chemical etching, electrodeposition, hydrothermal methods, and other chemistry-related methods. However, these methods are hampered by problems related to uniformity, controllability, cost, and efficiency. One solution is laser surface-structuring technology, a rapidly developing new technique that constructs micro- and nanostructures on metal surfaces. As a one-step maskless fabrication technique, laser surface-structuring has been applied to the reflection and wettability control of surfaces, electrochemical reactions, and microbial cell retention. This chapter discusses the fabrication of surface micro- and nanostructures on metals through laser surface structuring and their applications in typical areas.
