Electrolytic method for coloring titanium and titanium alloys

Titanium and its alloys are widely used based on their chemical resistance and high mechanical performance related to relative low specific weight. While titanium has traditionally been finished in dark gray wrought or silver polished states, the material can actually exhibit a spectrum of colors when a thin, amorphous oxide layer develops on its surface.

NanoSurfaces’s controlled electrochemical process allows titanium to produce unusual colors such as pink, blue, brown, green, and yellow with many different intensities and finishes. These colors are chemically resistant, may be applied to complex shapes, and are suitable for interior and exterior applications. When exposed to sunlight, the colors become particularly intense and vibrant.
