Capillary Array: Ti2O3 Coating

This type of coating is made of titanium oxide, which is a ceramic material that has high refractive index, optical transparency, and chemical stability. Ti2o3 coating can enhance the mechanical strength and optical transparency of the capillary. Ti2o3 coating can also form a protective layer of titanium nitride (TiN) on the surface of the capillary by nitriding at high temperature. TiN is a gold-colored material that has high hardness, wear resistance, and corrosion resistance
