Of the above, the most basic series SD3 and ND20 have 23 kinds of color patterns. Since these are not painted on the panel with pigments, they do not use pigments.
So why do you see the color despite not using color materials? This is because the color is expressed by adjusting a thin layer called oxide film.

 In the first place, color is observed by light reflection. For example, when we are in a dark room, we cannot see the color, but we cannot even determine the shape of the motif. This is a phenomenon that occurs because the object is not reflecting light. Conversely, you can distinguish the color projected on the smartphone screen even in a dark room. In this case, we can recognize it as a "color" because the monitor itself emits light.

In other words, humans cannot perceive the colors unless there is light reflection or light emission by light sources.

There are two types of colors, "Threelands of Color" and "Mikon Light". The former is also called a color reduction method, based on three colors, Cyan, Magenta, and Yellow. It is also called CMYK because it becomes black when these three primary colors are mixed evenly, and printed matter is made using these theories. Of course, paint also has this property, and you can make black by mixing the three -field paint.

The latter is called coloring method, and is composed of three colors, red (RED), green, and blue (blue). When these three lights are stacked, it becomes white, and the color of the display and screen is expressed by combining these colors. This expression is called RBG.

The image below shows the appearance of the appearance. On the right is "three colors of color", and the left is the "three -style light of light". However, as you can see when you actually mix the paint, even if you mix cyan, magenta and yellow evenly, it will not be completely black, so in the case of printing, black ink is used in addition to these three colors.

The color of Trantixxii® introduced this time is also called interference color, and it is also a phenomenon that rainbows are applied after the rain, the sky looks blue, and the soap bubbles look like rainbow. The thickness of the membrane used in Trantixxii® is up to 0.15 μm. 1μm is 0.001mm, so you can see how thin it is.

What kind of process is this oxidized film? newWe asked Mr. Naoaki Takimi of Wa -plating Co., Ltd. to ask about the mechanism.

The company has a factory in Joetsu City, Niigata Prefecture, has plated industrial products, and develops titaniums including TrantixXII®.

 
 

Mr. Takimi of Shinwa Plating Industry Co., Ltd. In Japan, they often see gas meters plating. There was a product of the company in an unexpected place.

The oxide film of the color titanium is performed called "galid oxide treatment". When a voltage is applied to the titanium immersed in a special liquid, hydrogen (minus), hydrogen, and oxygen is generated from the anode (plus), and the oxygen and titanium form a film of titanium oxide on the surface.

This process does not change its physical properties and durability when compared to other coloring methods, and there is no need to worry about it. The film thickness protects the material, so it is possible to keep the metal texture itself.
At first glance, it looks very simple, but the color changes depending on the time spilling this electrode, so a professional technology is required to get a uniform color development in mass production.
A mechanism in which the color changes by mixing the Mihara color is called a color ring, but the gradation in a ring is exactly the "color circle".

Mr. Takimi explains how the color changes depending on the time spent. The company has 60 kinds of color patterns.
 
 
Let's take a look at how titanium actually develops.
 
(1) First, make a liquid for the anodo oxidation.

(2) Prepare a special treatment titanium.
This time, the logo of this lab was engraved. It is unique to titanium that such a laser processing expression can be made. The titanium before processing is a dull silver.

(3) Put the voltage on the titanium immersed in the solution. It has changed to a slightly brownish color.

 
④ If you continue to apply the voltage as it is, it has changed to purple. It seems to be watching a phase ring experiment.
 

 
By pulling the titanium from the solution, you can control the voltage time on the material and create a gradation.
 

 

⑥ Here is the completed state. It is a beautiful gradation like when metal is burned with a burner. After this, the company performs the post -processing and is completed.

In the demonstration at this lab, we made Inoguchi and ruler.

The silky texture not found in other metals and the modern color texture is beautiful. Because it is light, durable and hard to deform, it is suitable not only for tableware but also for daily necessities.

TrantixXII® is a world -class material in Joetsu City, Niigata Prefecture. The possibilities have great potential not only for industrial products but also for art applications. This lab also sells small SD3 and ND20 for samples.

In 2020, Katsura Saito, an expert in this lab painting material, performs a demonstration produced by Trantixxii®.
