A few days later, in the reception room of foreign guests of Huaxia Commercial Aircraft Manufacturing Company, Anderson Fergus, a representative of Honeywell International of the United States, and Kelly Hall, a representative of Rolls-Royce, of the United Kingdom, were discussing and waiting.

Their purpose is the same, they are all in order to sell the manufacturing technology of engine blade materials to Huaxia Commercial Aircraft Manufacturing Company as soon as possible, and the two sides are competitors to each other, so it is inevitable to test each other and find each other's bottom line.

"Two, I've kept you waiting. Peng Zhengge walked from outside the door and said.

"Mr. Peng!" The two stood up and shook hands with him, eager to know the decision of Huaxia Commercial Aircraft Manufacturing Company.

Generally speaking, this kind of thing should be discussed separately, because no matter which side is rejected, it is more shameful. But today Peng Zhengge is not worried about this problem, because he does not need to reject either party, the other party will naturally understand.

"Before we talk about cooperation, I would like to invite you two more to visit our Institute of Aeronautical Materials. Today is the day we test the latest low-pressure turbine engine blades, and we invite you both to visit with us. Peng Zhengge said.

"That's right, I'm also interested. Anderson said.

"It's an honor. Kelly also expressed interest.

On the way, Kelly Hall also kept emphasizing the importance of their blade material technology to Peng Zhengge.

"Now the aero engines that Rolls-Royce manufactures for Airbus are all made with this new type of titanium-aluminum alloy blades. Its improved fuel efficiency has greatly strengthened the competitiveness of commercial aircraft. Airbus A350-800, A350-900, A350-1000 and A350-900ULR in development will all be made of this blade material. ”

Airbus relies on this fuel-efficient model to obtain a large number of orders from all over the world, competing with the Boeing 787-9 and 777-200ER passenger aircraft for the market. If Huaxia Commercial Aircraft Manufacturing Company can use this new material to replace nickel-based alloy blade materials, its market competitiveness will definitely be more than doubled!"

"Mr. Hall shares our thoughts, and our idea is to apply this new material to aero engines as soon as possible. Therefore, the purchased aero engine is also made of this new material. Peng Zhengge said.

"Yes. Kelly Hall continued the pitch, saying, "If we can work together on this material, your company will no longer have to spend a lot of money on this material, and you can make it yourself." ”

Before he finished speaking, Anderson also said: "We at Honeywell are also willing to cooperate like this. ”

"Two, let's talk about this after visiting the material testing of the Institute of Aeronautical Materials. Peng Zhengge said in a mysterious tone.

Anderson heard his tone, and inexplicably had a bad feeling, just like the previous large-area molding technology of carbon fiber composite materials, could it be that this time they have come up again?

If it is said that the Hongxin Group has developed carbon fiber composite materials for the manufacture of other high-tech equipment, but this time the material is only used in aircraft engine blades! It is unlikely that it will have the research and development technology in advance.

And Kelly Hall felt that Peng Zhengge was playing a mental war, so as to further let Rolls-Royce compete with Honeywell International and lower the price of each other.

At the Institute of Aeronautical Materials, the manufacturing process of engine blades is underway at the institute.

Zhong Bing, the technical representative of Hongxin Group, said: "The blade rotates at high speed, and any small, hidden metal fracture may cause the blade to break, so the blade must be formed in one piece, and there can be no second and third casting process!"

Gao Wei nodded and said, "We are also a one-piece design, but there is a problem. In titanium aluminum alloys, titanium is too active and reacts with almost all metals and ceramics. Integrally formed, you have to find the right shaped container!"

Zhong Bing carried a spherical quantum computer with him, he turned on the projection, and said: "Now there are three kinds of ceramics that do not react with titanium, one is thorium oxide, which is radioactive and cannot be used as a shaping container; the second is calcium oxide, which absorbs moisture and cannot be preserved; and only yttrium oxide can be used as a shaping container." ”

"We've thought about it. Gao Wei wondered, "The surface of the yttrium oxide shaped container is powdery, which is easy to drop slag and pollute the titanium-aluminum solution, so that the accuracy of the formed titanium-aluminum blades is not enough." ”

"That's right!" Kelly Hall interjected, "In the aeronautical materials laboratory in Germany, we used computer simulations to calculate that titanium-aluminum alloy blades longer than 200 mm cannot be formed in one piece. No matter what you do, you will encounter the problem that yttrium oxide slag will affect the accuracy. ”

"Not necessarily. Computer simulations can also be wrong. Zhong Bing said.

Kelly smiled: "I'm just reminding you that if you fail, we are willing to sell some of the technical data to help you complete the manufacturing of titanium aluminum alloy materials." As for blades with a length of more than 200mm, I advise you not to waste time. ”

"What we want to make today is a titanium-aluminum alloy blade of more than 200mm. Zhong Bing said directly.

Kelly Hall shrugged his shoulders and didn't say anything more, but the expression on his face already showed his thoughts, and he was waiting to see the show.

"Let's get started. Prepare titanium-aluminum solution, yttrium oxide solution. Zhong Bing shouted, and the working groups began to act.

"Mr. Lu, can you do it?" Peng Zhengge asked Lu Zixin in a low voice, "Today, I called the representatives of Rolls-Royce and Honeywell, if it fails, I can't hang it on my face!"

"Don't worry, today, you can see the appearance of titanium aluminum alloy blades, and they are definitely more than 200mm. Lu Zixin assured.

There is no problem with the titanium-aluminum solution, the most important thing is the manufacture of the yttrium oxide shaping container! As long as the yttrium oxide shaping container is made, and then the titanium-aluminum solution is poured into it, it can be formed in one piece.

Gao Wei has always worried that they have done similar experiments countless times. Every time due to various reasons, it failed, especially the problem of slag falling from the yttrium oxide shaping container, resulting in the accuracy of the titanium aluminum alloy blades has not met the standard, and they have not found a solution so far.

To make yttrium oxide shaping containers, when smelting yttrium oxide solution, Zhong Bing asked people to take a barrel of sealing solution.

"What is this?" Gao Wei curious.

"A molecular binder, specifically for yttrium oxide, allows its surface to be smooth and stable without slag. Zhong Bing said, and asked people to add the molecular binder to the yttrium oxide solution to form the yttrium oxide shaping container.

After a short time, when the solution cooled, the shaping container appeared! Unlike the results of many previous experiments, this time, the yttrium oxide shaping container no longer appeared in the state of surface particles and powders, but was as smooth as a mirror!
