PVD coatings: color control


A discussion started in 2001 but continuing through 2019


Q. I would like to know a PVD process for depositing coatings in different colors (red, blue...). Which is the best PVD process to make it? Which materials could provide the different colors?

A. Gold and brass colors are usually formed from zirconium nitride with small admixture of carbon. Chromium nitride yields silver. I don't know of any commercial work in red and blue, but would assume one can get blue by depositing titanium oxide. Erbium oxide yields a pinkish gray. The most common deposition process is by cathodic arc. Coatings are very thin -- around 200 nm.

A. I've some PVD plated steel samples that are in blue, black, grey and bronze colours, but I'm not sure the composition of the layer. Some French and Taiwanese platers can achieve those colours.

I've also read on the web that purplish red can be achieved by plating TiAlCN. You can surf the web for details. The plating is applied on tooling for wear resistance and high temp properties.

A. Silicon nitride is bright blue. Also oxides can be deposited (or metals such as niobium can be anodized) that give a red or blue appearance. You just have to ensure the oxide thickness is uniform to give a homogeneous colour.

A. We can get violet to red colors in TiCN by varying the Methane to Nitrogen gas ratio. Ratios are preferable like Methane:Nitrogen = 1:5 Red-ish yellow, like 1:4, 1:3, 1: 2, 1:1(gray color).

PVD in Tungsten Rings - How to get the right gold color

November 29, 2015

Q. Hi dears. I've been importing tungsten rings from China for a year. I know that in China they make a kind of PVD; the color is good but the plating is a kind of "flash", and fades within 1 year. I'm trying to make the PVD with many companies here in Brazil, but they are not finding a good color for jewelry (gold color). Although they are international companies, they specialize in tools, car parts, etc., so, its been very difficult to get the exact color. How can I get this color? Is there someone who has a kind of % of TiN or other elements to get this color? Someone can help me? Thank you so much.

A. Andre,
As you might have already figured out, there are companies that specialize in functional PVD coatings and those that specialize in decorative PVD coatings. Decorative PVD coatings are very commonly deposited on faucets and door hardware. As gold PVD is pretty common in the faucet business, replacing gold plating, look for a company in Brazil that makes high end faucets. They either do the PVD coating themselves, or can lead you to their PVD coating supplier.

Q. This was also my question and I could not find any answer. I have read on the web that coated layer color depends on some factors such as target material, substrate material, layer thickness and .... I am interested in knowing about controlling these factors to make different colors. Is there any resource which provides details on how these factors can be controlled to make different colors?

A. PVD color depends primarily on the target material and the reactive gas mix. For example, you get yellow gold with a titanium target and nitrogen gas. Adding methane or acetylene darkens the finish, going to reddish gold to gray to black. There is no general recipe, just recipes that work for a specific PVD system design.

Q. I'm from VietNam. We are very new in PVD industry. My customer ordered polished stainless steel PVD champagne rose color (not gold base); it looks like "coffee color". What kind of target, gas, could we do to get this color?

A. Specifying a coating only by colour is risky not least because colour perception is rather subjective. Coffee (is it with or without milk ?!) comes in different tastes and colours. Apart from colour the user would be having other expectations from the coating. Some form of TiCN or TiAlN may serve the purpose. It would be best to have a joint discussion with the machine supplier and your client.

Q. I am having trouble with a couple of my PVD finishers who say we must lacquer or clear coat "to prevent oxidization".

Done properly, would a PVD finish done on SS require a lacquer or a clear coat?

thumbs up sign Hi Allen. Are we talking architectural building panels, or plumbing faucets, or wristwatch dials? My belief is that gold colored PVD coatings are generally a final finish, but unfortunately, I think people would need to know a lot more about what you are doing before they could say whether your finishing shops are doing something wrong and trying to talk you into putting a bandaid on it.

PVD is a somewhat generic term, and includes deposition of hard coatings as well as metals. If your PVD finish is a hard metal nitride, oxide, or carbide, or some combination thereof, it should not require a top coat, assuming that you are using a 300 series stainless steel. If it is just a metal coating -- say nickel -- it probably needs a top coat.

thumbs up sign Hi Brint. You're certainly welcome to ask. But people who have achieved success at it are also welcome to retain that know-how to further their own business interests. So I don't know whether any answer will be forthcoming :-(

Q. Hello and Greetings,
I deposit TiN thin film on faucets and steel dishes.
TiN color is golden, but when titanium target was finished, I mounted new titanium targets … all parameters were the same, but color was very pale. Does anyone know why the TiN is colorless?

Q. My situation: I have done several tries to get copper colour in PVD, though I succeeded in getting that colour through copper targets, but it gets tarnished after some time is there any other way I could achieve copper colour or a colour near to that of copper

A. I don't know of anyone who has had success producing a copper finish by PVD other than depositing copper. Many have tried.

A. Hi guys

I work for a Mexican factory and we make Gold PVD using TiZr targets with Nitrogen gas, the key to get a good color is proportion of gas and adjust bias control to get very stable coating.

A. Hi Tej. The easiest way is to just vacuum metallize with aluminum and tint your top coat instead of leaving it clear. Cracker Jack toys and children's toy finger rings sold for 5¢ in gumball machine have been made this way for decades. Good luck.

PVD deposit is perfect bronze red, but just gold in deep holes

February 27, 2019

Q. Hi,

Anyone know how to solve pvd deposition with Ti targets and bronze red colour TiCN. Problem I have is that colour not getting deep enough . In deep holes about 4 cm and 8 in diameter I get just gold colour, while outside it's perfect bronze red.
Thanks for answer.

A. Hi Alan,
you can try to increase your deposition time; also you can try to modify your fixture for a better deposition rate.
