Titanium - Color games with excitement


 

Anodizing #Titanium is an electrochemical process and not a coating.

Unlike the PVD process, no material is applied to the surface, but an oxide layer is built up. The titanium discolors by the application of a voltage, usually between 12V and 100 V, in an electrolyte. The perceived color of the anodized titanium is related to the thickness of the titanium oxide layer. The color perception of humans is related to the wavelength of light.

The oxide layer of titanium is transparent. When light hits the surface of the titanium layer, it is refracted or dispersed. The refraction of the light produces a different wavelength. Depending on the wavelength produced, this is detected as a color by the human eye. However, the titanium oxide layer is many times thinner than that of the perceived light. The oxide layer and the wavelength of the light must produce a common multiple in order to produce the desired color.


A layer thickness of 10-25 nm results in a gold color, 25-40 nm in purple, 40-50 nm in dark blue, 50-80 nm in light blue, 80-120 nm in yellow, 120-150 nm in orange, 150-180 nm in purple, 180-210 nm in green. Thus, beautiful color combinations are possible and each component is unique.


These three unique pieces were raffled off in our Easter promotion 2022.

 

We will bring color into your bathroom and also gladly manufacture your desired color on request.

 

The color change takes place in a few seconds.
