Abstract
This study focuses on laser-induced oxidation of TC4 alloy surfaces and achieves precise color control on TC4 surfaces at room temperature using laser post-processing. The current research lacks an in-depth understanding of the mechanism responsible for color changes due to the number of processing cycles. This study aims to improve the quality of coloration through secondary processing and establish a color control mechanism based on accumulated energy density. Statistical analyses revealed notable reductions in ΔE, ΔC∗, and Δh∗, indicating enhanced color uniformity. Surface morphology and reflectance data further confirmed these findings, demonstrating the effectiveness of secondary processing in achieving consistent and uniform coloration.
期刊介绍：
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
