The rise of nanometers

Ice city.

703.

The research institute, which had been half-dead in previous years, has gained a lot of popularity this year. After cooperating with Beifeng Company, they received a research fund of 80 million yuan last year. In early January this year, they received an additional 240 million yuan in funding.

Don't think that this money is a lot. For heavy-duty gas turbine research projects, the research funding is basically in units of hundreds of millions and meters.

For example, General Electric invested 200 million yuan in 2008 to build the world's largest full-speed no-load test bed in South Carolina.

Companies such as General Electric, Siemens, and Mitsubishi have made similar investments over the past few decades.

However, the combined annual investment of several domestic research institutes and enterprises is not even a fraction of others, but they have built a lot of houses.

Therefore, the 320 million invested by Beifeng Company is nothing at all.

The main factory area of ​​Beifeng Company is located in Bingcheng, close to the 703 Research Institute.

Chen Xuedong, chief engineer of the 703 Research Institute, and a dozen engineers from Beifeng Company, as well as engineers from Snail Steel, were discussing how to improve a heavy-duty gas turbine.

Dong Xincheng, an engineer at Snail Steel, shook his head after reading the test data: "No, it still won't work. To improve performance, we can only increase the combustion temperature and gas pressure. The problem is that your materials cannot support it."

Chen Xuedong also looked helpless: "We have already adopted Baosteel's latest high-performance steel unless we import high-temperature resistant materials."

"No, it seems we still need to take action from our factory."

"Um? Your company's silicon nano-coating is indeed very powerful, but under ultra-high temperature operation, the service life is only a few months. You can't shut down and re-plating every few months, right?" Chen Xuedong immediately objected.

The 703 Research Institute has tried using silicon nano-coating before, and the effect was very good at first. However, after testing for a period of time, the gas turbine blades deformed rapidly.

After taking it apart for inspection, it was discovered that the silicon nano-coating had been damaged by high temperatures.

Dong Xincheng shook his head: "It's not silicon nano-coating, and our company doesn't only have one kind of material. I'll make a call and ask about the situation."

After saying that, he ignored everyone who was confused and went to the office to make a phone call.

Snail Steel, a subsidiary of Snail Industry, has the most luxurious alloy research institute in the world. It is said to be the most luxurious because it has a large number of nanomaterials that ordinary companies do not have.

Nano-pure iron powder and nano-pure aluminum powder are trivial, while nano-tungsten powder and nano-bismuth powder are also commonplace.

There are also some raw materials that are in short supply around the world, such as nano-rare earth elements and nano-rhenium powder, which are rarely available on the market.

He Wen, who was transferred from the Shanmei Scientific Research Department Headquarters, is the Chief Technology Executive Officer of Snail Industry and concurrently serves as the Director of the Alloy Research Institute.

He Wen, who had just come out of the laboratory, took the call from his assistant.

"Hey, Xincheng, how's the situation over there?"

"Forget it, Baosteel's steel still doesn't meet the requirements, and system design is very difficult in a short time."

He Wen's mentality is the same as that of Der Spiegel. The overall performance of industrial products often depends on two factors, namely materials and design.

The material is the foundation, and the design is just the icing on the cake.

Just like the N20 high-energy material developed by their company, the material performance has improved, and the performance of the launch vehicle has directly and explosively improved.

Without N20, based on the original fuel, even if the design is extravagant, the performance will not change qualitatively.

Therefore, if domestic gas turbines are to develop significantly, the focus should be on materials at this stage.

"You want to ask about our company's high-temperature resistant materials?"

"Yes, Mr. He, what is the current situation of our company's high-temperature resistant alloys?"

He Wen smiled and said: "If you had been half a month earlier, I wouldn't have been able to answer. A week ago, our rhenium-tungsten alloy steel had already determined two preliminary formulas. One of them is a formula that can be mass-produced and can withstand 2137 degrees Celsius. extreme temperature."

"How difficult is it to process?" Dong Xincheng asked because the hardness of tungsten steel is extremely high and is very unfriendly to processing.

"It's okay. The hardness of this formula is not too high. We can use powder metallurgy to create a rough embryo and then carry out deep processing. At most, some of the tool bits will be lost."

"Then I will send over the necessary spare parts and make a batch to try."

"no problem."

Half an hour later, through the internal network of Time Information, Beifeng Factory sent a batch of design drawings of spare parts that required high-temperature resistant materials to Cangzhou's Snail Steel Factory.

The Beifeng Factory's industrial software uses time information, which is basically the same as that of Snail Industry. Therefore, as soon as their design drawings come over, they can enter the production workshop for production.

Powder metallurgy workshop in a steel plant.

The technician selects a recipe and flips the switch.

The automation system of the workshop controls the equipment and generates high-temperature resistant alloy bit by bit. Powder metallurgy is a delicate job.

Dozens of blades were being produced at the same time, and technicians checked the production status from time to time. After more than three hours of continuous operation, the first batch of blades was freshly produced in the powder metallurgy workshop.

He Wen picked up one of the pieces. It was still a relatively rough rough embryo and needed further processing before it could be turned into a qualified product.

Soon several technicians sent these blades to the deep processing workshop.

After preliminary processing on the CNC machine tool, the blades were ready for use, but the technicians did not stop.

Snail Industry has a very special deep processing technology, which is a nano-scale processing technology developed based on six-cone spherical oxygen.

After a series of tests, such as crystal lattice and internal cracks, if there is any problem, the part can only be scrapped.

Finally enter the nano processing workshop.

Several technicians looked at the design drawing parameters on the computer. After laser scanning, the actual size of the part and the design drawing parameters must be consistent. If there is no consistent position, the system will automatically mark it out.

The workshop leader ordered: "Start processing!"

The surface of a blade is 3.73 microns thicker than the design parameters. A specially customized surface etching machine is closely attached to the surface of the blade.

"The seal is OK."

"Inject etching solution."

"Power on for two seconds."

After two seconds, the etching head leaves the blade surface.

There is a corroded damage layer on the surface, and the tungsten element there has been stripped away. The grinding head of the robotic arm is attached to the surface, grinding it quickly for a few seconds, and then cleaning the surface.

By continuously repeating this set of processes, the dimensional accuracy of the blades will basically reach 10 ± nanometers, which is considered a qualified product.

Starting from powder metallurgy, rough machining and nano-finishing, it takes about a week to complete the processing of such a part.

It took Snail Steel more than a month to process this set of gas turbine spare parts. This set of spare parts, which represent the most sophisticated parts in the world, was transported from Cangzhou to Bingcheng.

Not long after the Spring Festival, several large trucks delivered these expensive spare parts to the Beifeng Factory in Bingcheng.

After obtaining these parts, Chen Xuedong, Dong Xincheng and others immediately organized engineers to start assembling a new generation of gas turbine engines.

At first, they didn't find anything, but when they installed the parts, they discovered that these parts were abnormal, and they didn't even feel the existence of tolerances.
