Abstract

The lightness and high strength-to-weight ratio of the magnesium alloy have attracted more interest in various applications. However, micro/nanostructure generation on their surfaces remains a challenge due to the flammability and ignition. Motivated by this, this study proposed a machining process, named the ultraprecision diamond surface texturing process, to machine the micro/nanostructures on magnesium alloy surfaces. Experimental results showed the various microstructures and sawtooth-shaped nanostructures were successfully generated on the AZ31B magnesium alloy surfaces, demonstrating the effectiveness of this proposed machining process. Furthermore, sawtooth-shaped nanostructures had the function of inducing the optical effect and generating different colors on workpiece surfaces. The colorful letter and colorful flower image were clearly viewed on magnesium alloy surfaces. The corresponding cutting force, chip morphology, and tool wear were systematically investigated to understand the machining mechanism of micro/nanostructures on magnesium alloy surfaces. The proposed machining process can further improve the performances of the magnesium alloy and extend its functions to other fields, such as optics.
