Laser-Induced Color Marking of Titanium: A Modeling Study of the Interference Effect and the Impact of Protective Coating

Figure 8

The results of a four-layer system modeling in order to retain the original color ((A) red, (B) purple, (C) blue, and (D) light blue) after application of protective coating of a known refractive index: (a–c) reference sample without the 3rd layer, (d–f) effect of application of 20 nm of the 3rd layer, and (g–i) the adaptation of the oxide thickness in order to reproduce the expected color after the application of the 3rd layer.
