The biggest difference between the color film layer and the conventional color film layer is the C value and the H value, so it can be said that black is also a color film layer.

Zirconium + nitrogen: yellow-green tones golden yellow

Zirconium + methane: dark and light black

Zirconium + oxygen: white, transparent film

Zirconium + nitrogen + methane: gold, imitation rose gold

Chromium + Methane: Dark and light black

Chrome + nitrogen: light black

Chromium + nitrogen + methane: silver gray

Chromium + oxygen: light yellow, purple, green

SUS + Oxygen: Purple

SUS + nitrogen: blue

SUS + methane: bright black

SUS + methane + nitrogen: blue-black

Silicon + Nitrogen: Black

Silicon + oxygen: cloudy white, transparent film

Silicon + methane: yellow, green, blue, black (target purity higher than 99% can only be adjusted to black)

Titanium + Oxygen: The optical film is colorful, and you can understand it without much introduction.

Titanium + methane: dark and light black (DLC preparation cannot meet the standard)

Titanium + nitrogen: imitation gold, brass, purple, red

Titanium + nitrogen + methane: imitation rose gold, black green, vintage yellow, brown, purple

Tungsten + nitrogen: brownish yellow

Tungsten + Methane: Dark and light black

Tungsten + oxygen: purple, bright yellow, brown, blue

The above are only the common materials for decorative films and their common gases, usually methane and acetylene are interchangeable, but the effect of methane in some colors is better. In addition to the above commonly used materials,

Metal targets include nickel, aluminum, tantalum, hafnium, manganese, copper, zinc, indium, tin, etc., all of which are used in coating. Multi-material targets such as titanium aluminum, chromium aluminum, titanium zirconium, copper manganese, nickel chromium, silicon aluminum, vanadium rhenium, tungsten molybdenum and so on.
