In this paper, we exhibit the colorizing of brass surfaces by forming femtosecond laser induced microstructures on the sample surfaces. A variety of single colors such as brown, yellow, green, and black are introduced on brass surfaces by engineering periodic microgratings, microholes, and ring-shaped micropatterns using Single Beam Direct Laser Writing (SBDLW) technique. The color of the micro-structured brass surfaces is certainly dependent on the width, depth, and period of the microstructures. Finally, we explain, in brief, the colorizing mechanism of metals by femtosecond laser induced microstructures. (C) 2012 Elsevier GmbH. All rights reserved.
