Material Empire

Hearing Qin Hai speak so solemnly, Li Linguang smiled. He has never thought about owning any patented technology. It is his interest to engage in scientific research. Patents and non-patents are meaningless to him. In the past two years, he has done some things for Pingyuan Special Steel Factory, and Qin Hai has paid him generous remuneration every time, which already made him feel a little sorry. What Qin Hai is talking about now is nothing more than a new research task in his opinion, and it doesn't matter if you give him money or not, let alone the issue of patent ownership.

"Xiao Qin, what makes you so cautious? Before you start doing this, you have to consider the issue of patents first." Li Linguang asked.

Qin Hai also felt that his attitude seemed a bit too solemn, he smiled and said: "I just said that wrongly, I want to own the relevant patents, but you can get 20% of the income obtained from this, what do you think?" ?”

"I don't want even a cent." Li Linguang said carelessly, "I have a salary, what do you want for your income? Xiao Qin, you are used to being a capitalist now, and you only think about money in everything."

Qin Hai said sternly: "This technology is really important. If it can be developed, the annual market value will not be less than 10 million. The two achievements will be no less than 2 million...Mr. Li, you really don't care?"

"No less than ten million!" Li Linguang was taken aback by the number Qin Hai said. He looked at Qin Hai's expression seriously and made sure that Qin Hai was not joking. His expression became serious and he asked: "Xiao Qin, what kind of technology do you have such confidence in?"

"I want to attach a layer of titanium nitride to the tip of the rotary tillage blade. What do you think?" Qin Hai was not in a hurry to tell his design, but asked him according to the ideas that Li Linguang could deduce. Because in this way, Li Linguang will not feel too abrupt about the thermal spraying process he proposed.

Li Linguang thought for a while and said: "The Vickers hardness of titanium nitride can reach up to 2,500 and its melting point is close to 3,000 degrees Celsius. It is indeed a suitable material for making high wear-resistant tools. But, what method do you plan to use to attach it to the metal?" On the surface?"

Qin Haidao: "The traditional method will definitely not work. When I was in Beijing this time, I read some foreign materials and found that foreign countries are making very fast progress in spraying technology. Can we use this method to convert titanium nitride Particles coated on metal?"

"Are you talking about the spraying process? I have read related literature, but the spraying method requires a high-energy, high-speed plasma generator. The cost of this equipment is beyond what we can imagine. It is used to make farm tools. Doesn’t it mean that anti-aircraft guns hit mosquitoes?” Li Linguang reminded.

Qin Hai smiled slightly and said, "That's where my idea comes from. Teacher Li, think about it, if we don't use plasma equipment, but use ordinary flame spray guns to generate high-speed particles and make them hit the metal surface , can it also produce the effect of spraying? You see, the plan I envisioned is like this..."

Having said that, Qin Hai took out a pen and paper, and drew a schematic diagram for Li Linguang on the dining table. The schematic diagram he drew is actually nothing more than a high-speed flame spray gun that has become very popular in later generations. Its principle is also very simple, that is, to send oxygen and fuel into a closed cavity, make it burn, expand, and then erupt through a nozzle. go out. The sprayed materials are sent into the nozzle from another port, so that the high-speed gas will carry these materials and impact the surface of the substrate to achieve the effect of spraying.

Among them, of course, many key technical details are involved. These details still troubled material scientists around the world back then, but for a traveler like Qin Hai, it is very simple knowledge. He pointed a few words to Li Linguang, and Li Linguang nodded repeatedly, his face gradually filled with excitement.

"That's right, that's right, this idea should be right!" Li Linguang couldn't help but praise, "Xiao Qin, how did your brain grow, how could you think of this way?"

As an expert in materials, Li Linguang could hear the feasibility of Qin Hai's proposal. Although this is just an idea, it is not far from reality. He knew that if Qin Hai's idea can be realized, the threshold of thermal spraying process will be greatly lowered, the price of equipment will be two orders of magnitude lower than now, and the cost of spraying will be low enough to be popularized.

Once the thermal spray process becomes simple and inexpensive, the application of this technology will become very common. The field of agricultural machinery is just a very small market for it. Fields such as mining machinery, hardware tools, and even military affairs will use this technology in large quantities to improve product performance. At that time, the value of this market will not be tens of millions as Qin Hai said. , but may reach hundreds of millions or even billions...

No wonder Qin Hai is so serious about this matter, no one will be indifferent to a technology with such a future.

Seeing the surprised expression on Li Linguang's face, Qin Hai knew what he was thinking, he smiled and said, "Hehe, Mr. Li, this is just an idea. If it is to be realized, I may have to ask you to come out of the mountain." Woolen cloth."

This is not a word of modesty. Although Qin Hai understands the technical know-how of the entire thermal spraying process, it still requires a lot of experiments to truly turn it into an operable technology, such as the temperature of the flame, the speed of the airflow, nitrogen The size of titanium oxide particles, etc., all need to be determined after experiments. If Qin Hai was given enough time and enough assistants, he would be able to organize such an experiment by himself, but he had more to do than this. With a helper like Li Linguang in front of him, he Why not?

"This matter is very interesting. I will accept this task." Li Linguang did not show extra politeness, and directly agreed to Qin Hai's request. However, to do these experiments, it is not enough to rely on him as a material expert. The design and manufacture of spray guns is not something he is good at, so he hastened to emphasize: "For this matter, Professor Yue Kun from the Department of Mechanical Engineering must be invited Come and participate, the design of this spray gun is not a simple matter, Lao Yue is an expert in this field. In addition, the design of the spray gun has to be found in a factory to produce it."

This question was also thought about by Qin Hai, and he said, "I'll leave it up to Teacher Li to invite Professor Yue. In terms of fees, how much do you think is appropriate?"

Li Linguang waved his hands, and scolded angrily: "Three sentences are not far from the line, do you think Lao Yue came to help because of the money you gave?"

Qin Hai hurriedly said with a smile on his face: "I know, I know, but if you hire someone to do something, you have to be paid, or my conscience will be uneasy, right? How about this, Teacher Li, please ask Professor Yue to help, every month Based on the remuneration of 500 yuan. If he brings students to help, no matter how many students, each student will get 100 yuan per month, what do you think?"

"Okay, then I will thank you for your kindness on behalf of Lao Yue." Li Linguang nodded and accepted the price offered by Qin Hai. In the past, when he worked for Pingyuan Iron and Steel Plant, Qin Hai paid him more than that, and he was used to it. Although he said that Yue Kun would not care about remuneration, but Qin Hai could give some remuneration, so it would be easier for him to talk about this matter with Yue Kun.

Qin Hai went on to say: "As for the production of spray guns, you can leave it to Qingfeng Factory. Qingfeng Factory itself is a machinery factory, and there is no major difficulty in ordinary machining. If you encounter higher-precision processing tasks, you can ask Director Ning went to other companies for assistance, and his avenues are very wide."

"Okay, then it's settled." Li Linguang said.

"In terms of funds, I will ask Song Hongxuan to allocate 200,000 to you first. If it is not enough, you can tell Xiao Song at any time, what do you think?" Qin Hai said again.

"How can we spend so much money?" Li Linguang said subconsciously, 200,000 yuan was considered a huge sum of money back then, and Li Linguang couldn't figure out why he needed to spend so much money for a research.

Qin Hai didn't bother to explain too much to Li Linguang. He knew that although he had drawn out the key path, Li Linguang would need to devote innumerable manpower and financial resources to complete this research. Take the spray gun used in thermal spraying as an example, the material must meet the requirements of high temperature and high pressure resistance, and the price is very expensive. To finalize the design, I don't know how many versions will be designed. Just the cost of trial production, this mere 200,000 yuan may not be enough.

Li Linguang also stayed in a small temple like Anhe Institute of Technology for too long, lacking experience in undertaking large-scale scientific research tasks, so he has no direct feeling about funding.

"Ms. Li, don't worry about how much money you have. My requirement now is that, no matter what the cost, I must get the technology and equipment out within 2 months, so that I can catch up with the farming equipment expo in 3 months. Yours Can it be done?" Qin Hai asked.

Li Linguang said: "Time is indeed tight enough, but don't worry, since I dare to agree, I will definitely not delay your affairs. I will go to Lao Yue tonight and send the graduate students from their department to the graduate students from our department. Everyone is mobilized, and everyone works overtime, after all, this is also a matter of winning glory for the country."

"Well, it's indeed more appropriate to use this slogan." Qin Hai smiled. Although the saying "everything depends on money" has become popular in society, sometimes some political slogans are more effective in schools Yes, at least it can satisfy the school. Qin Hai speculates from his own experience that if the overtime pay for students and teachers is adequate, plus the political honor after winning an international award, it should be enough for everyone to work without sleep or food.

With Li Linguang's ability, it is relatively safe to come up with a set of thermal spraying equipment that can basically meet the needs in two months. Qin Hai has enough confidence in this "sweeping monk".

"By the way, Mr. Li, let me add one last point. The authorship rights of the papers produced during this process belong to you, and you can publish them. I only need the final patented technology." Qin Hai said lightly. Li Linguang promised a great benefit.
