Monster Factory Chapter 379: : This is the real sintering

The more you think you have an understanding of something or technology, the easier it is to think that you have seen something wrong after seeing something you cannot understand.

Kobayashi and his team believe that Nikkei University has far surpassed Zhongyun University in the research of powder metallurgy technology.

Then I felt very funny after seeing Ye Qing's blending technique that looked like blending paint.

high-purity alcohol has volatile properties and can theoretically act as a humidifier. However, when used in various metal and non-powdered metal, chemical reactions may occur, and the density of powder increases due to the compression of the blank by the hydraulic press, and the phenomenon that the internal alcohol cannot be completely volatilized.

To solve this problem, you need to put the embryo aside for a long time naturally to let the alcohol completely evaporate.

This is a waste of time, and secondly, it is placed naturally. After the blank is dried, it may be slightly deformed, which increases the failure rate of the product.

This kind of technology has long been eliminated from their side and changed to a special humidifier.

There is also mixing. There is only a backward ball mill in this laboratory, and now the 3D sports mixer is the standard instrument in the first-class laboratory.

Too bad, I can’t complain!

Kobayashi has a feeling of backwardness in visiting a university laboratory before returning to 30.

Ye Qing turned a deaf ear to those sneers and mocking glances at Nikko University. He mixed the five main powders, then put them into ring molds of different specifications, and used a hydraulic press to die-cast them into five circles of different sizes. shape.

The smallest round accessory is only the size of a wine bottle cap, and the largest is similar to a bracelet.

If you measure their diameters, you will find that these rings grow from small to large, and the outer straight of each ring is slightly larger than the one above.

"Do you want to make the Olympic rings?" Tanaka smiled unkindly: "The 2020 Olympic Games will be held in our country. Speaking of which, the opening ceremony will be the location of the [New National Arena], which contains mechanical automation system. , Our school is still responsible for the design."

An industrial microscope used to observe the microporous structure of the material surface was adjusted by Ye Qing to focus, and then observed with the help of the microscope, Ye Qing used a micrometer to carefully measure the size of each circular embryo while using a cutter , Carefully engrave a semi-arc concave and convex surface similar to a gear on the edge of each blank.

After all the engraving, Ye Qing assembled the five ring sleeves accurately, and then recast them with a hydraulic press.

Those half-arc concave and convex surfaces, after being cast by a hydraulic press with 500 tons of pressure, they magically merge together.

Without giving them time to appreciate, the blank parts were assembled and sent directly by Ye Qing into the preheated vacuum sintering furnace.

No one is talking on Zhongyun University, they are all nervously watching the temperature rise in the sintering furnace.

Ye Qing looked at the watch on his left hand and said calmly: "Wait another twelve minutes."

"Would you like me to count the time for you?" Kobayashi ostentatiously, raised his left hand, and showed a watch with a silver-white dial and a Aventador metal strap, shaking: Seiko Minute Repeater mechanical watch with chronograph With watch function, the error of daily travel time is controlled within 0.5 seconds. "

"Uh..."

Ye Qing tugged on his sleeves to cover this one in his hand. worldwide only has a few pieces of the Patek Philippe2499 red gold series handed down, and said with some difficulty: "No...use it."

Some opposing atmospheres continued until the vacuum arc furnace was re-injected with protective nitrogen to balance the internal and external atmospheric pressures before being broken by the tension of immense.

"It will definitely break into glass." Kobayashi whispered in the ear of Tanaka classmates, without worrying that they would be overturned here.

Ye Qing smiled, wearing heat-resistant gloves, using special pliers, from the inside, pinched a fiery red disc that looked a little like a jade birch.

The fiery red disk is like a magnet, and it instantly attracted everyone's attention.

In the powder metallurgy laboratory, there was a sound of inhalation.

"It's not broken?" Professor Kobayashi Sei rubbed his eyes, how could he be surprised.

When the object is heating, due to the heat transfer of the material, if there is a crack on the object, it will become a very obvious black gap. But the fiery red disc in front of me is completely a whole.

The flaming red disc, fading away the residual heat little by little.

A touch of emerald green appeared on the outermost periphery of the disc first. Under the hot halo around, the emerald green on the outermost periphery became anomaly transparent, shining like emerald-like crystal luster.

Followed by the second flaming red fade, the silver-white metal contour makes Kobayashi's eyeballs become bigger and bigger in the process of staring.

Next is the third purple, then the fourth white, and the fifth transparent...

Green, silver, purple, white, transparent. Five different colors are combined, and they are intertwined with each other, completely natural.

Silver and white are metal materials, and the other three are nonmetal materials.

The sintering between different metal and metal is already a big piece of high-end technology. But what Ye Qing is holding now are five different colors and different types of sintering.

The laboratory lighting just gave it the hazy five-color luster of one layer. With the last bit of fiery red fading~IndoMTL.com~ This exquisite disc seems to be alive, and there is life flowing inside.

"Impossible!" The Tanaka classmates who only showed two kinds of metal sintering in the afternoon, jumped up, not only breathing, but also thinking.

There are no gaps, it's natural.

"The melting point between metal zinc and quartz is quite different by 1150 degrees. I want to make quartz sintering a transparent color, and metal zinc, which has a melting point of only 420 degrees, has long been melted into a pool of waste."

"This is not scientific."

"You said that it is pure zinc, but don't you know that the most common way to use zinc is to mix it with other metal and turn it into an alloy?"

"I don't believe it, then tell me. Even if it is a zinc alloy, how can it be perfectly combined with quartz?"

There are not so many reasons. When the five-color disc cooled down, Ye Qing directly handed it to the Nikkei University.

They put the five-color disc under the industrial microscope without giving up, and looked at it with the most piercing eyes, but still couldn't find any cracks in it.

On the Zhongyun University side, I fell into the joy of tasting the fairy fruit of the flat peach garden.

Want to get into the five-color disc at the Japanese University of Science and Technology, and get a glimpse of the expression of the mystery of the atomic structure inside, making them feel refreshed from the soles of their feet to the sky.

Has it been better?

The five materials sintering, how many times higher than the two materials sintering?

This is not even the difficulty between metal and nonmetal. It is not at the same altitude. The Himalayas can't match the gap between the sky.

"Have you seen enough?" Freshman Yun Tianjie walked up to the Tanaka classmate as a winner.

"Hey ~ losers, you should fulfill your promise and apologize to us." (To be continued.,, your support is my biggest motivation.) 16-11-0307:18:32
