Universidad de Zaragoza Generating colours through a novel approach based on spatial ALD and laser processing 2023 Access copy available to the general public Unrestricted This work studies the combination of direct femtosecond laser structuring of metal surfaces and Spatial Atomic Layer Deposition (SALD) of metal oxides as a novel approach to generate colours on different types of day-to-day metallic objects. In particular, a stainless-steel knife and an outdated 25 ct Dutch florin coin have been selected for the study. Our results show that it is possible both, to preserve the iridescence properties produced by laser processing and to tune the final metal surface colour by controlling the thickness of the ZnO coating. At the same time, this oxide coating could act as a protecting layer for the original material. We thus explore two different strategies to generate colour, namely, iridescence and interference, which can be even developed selectively. This novel methodology to colour metallic surfaces is a promising route to achieve cheap, scalable, and high-throughput processing methods and opens up a new avenue of possibilities and applications related to colour. info:eu-repo/grantAgreement/ES/DGA/T54-23R info:eu-repo/grantAgreement/EC/H2020/801464/EU/ Ultra-versatile Structural PRINTing of amorphous and tuned crystalline matter on multiple substrates /SPRINT This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 801464-SPRINT info:eu-repo/grantAgreement/ES/MICINN/AEI/PID2020-113034RB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 8.1 2023 MATERIALS SCIENCE, MULTIDISCIPLINARY 72 / 439 = 0.164 2023 Q1 T1 1.826 2023 Mechanical Engineering 2023 Q1 Materials Science (miscellaneous) 2023 Q1 14.3 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sekkat, A.
