Li Linguang laughed when he heard Qin Hai speak so solemnly. He had never thought about owning any patented technology. Scientific research was his hobby. If it was not patented, it would mean nothing to him. In the past two years, he had helped Pingyuan
The special steel factory had done some things, and Qin Hai paid him generous rewards every time, which already made him feel a little bit embarrassed. What Qin Hai was talking about now, in his opinion, was just a new research task.
It doesn’t matter if you don’t pay, let alone the ownership of the patent.
"Xiao Qin, what makes you so cautious? You have already considered the patent issue before we even start." Li Linguang asked.
Qin Hai also felt that his attitude seemed a bit too solemn. He smiled and said: "I just expressed it wrongly. I want to own the relevant patents, but you can get 20% of the income gained from it. What do you think?"
?”
"I don't even want 10%." Li Linguang said carelessly, "I have a salary, so what do I want from your income? Xiao Qin, you are used to being a capitalist now, and you only think about money in everything."
Qin Hai said seriously: "This technology is really of great importance. If it can be developed, the market value will be no less than 10 million a year. The two achievements will be no less than 2 million... Teacher Li, do you really not care?"
"No less than ten million!" Li Linguang was startled 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 is it that you have so much confidence in?"
"I want to attach a layer of titanium nitride to the blade of the rotary blade. What do you think?" Qin Hai was not eager to tell him his design, but asked him according to the idea that Li Linguang could deduce. Because of this
Later, Li Linguang would 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 more than 2500, and the melting point is close to 3000 degrees Celsius. It is indeed a suitable material for making highly wear-resistant machines. But how do you plan to attach it to the metal?
What about on the surface?”
Qin Haidao: "The traditional method will definitely not work. When I was in Beijing this time, I read some foreign information. I found that foreign countries are making very fast progress in spraying technology. Can we use this method to make titanium nitride?
Particles applied to metal?”
"Are you talking about the spraying process? I have read relevant literature. However, the spraying method requires a high-energy, high-speed plasma generator. The cost of this equipment is beyond our imagination. It is used to make agricultural tools. Yes
Isn't it a bit like using anti-aircraft guns to kill mosquitoes?" Li Linguang reminded.
Qin Hai smiled slightly and said: "This is 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 impact on the metal surface
.Is it also possible to produce a spraying effect? Come to see, the plan I envision is like this..."
Having said this, 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 was actually nothing more than a high-speed flame spray gun that has become very popular in later generations. Its principle is also very simple, which is to use oxygen.
and fuel are sent into a closed cavity to cause it to burn and expand. Then it is sprayed out through a nozzle. 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.
Achieve spraying effect.
Of course, there are many key technical details involved. These details still troubled materials scientists around the world back then, but for a traveler like Qin Hai, they were very simple knowledge. He mentioned to Li Linguang
After a few words, Li Linguang nodded repeatedly. An expression of excitement gradually filled his face.
"Yes, yes, this idea should be correct!" Li Linguang couldn't help but praise, "Xiao Qin, what kind of brain do you have, how can you think of this method?"
As an expert in materials, Li Linguang could hear the feasibility of Qin Hai's proposal. Although it was just an idea, it was not far from reality. He knew that if Qin Hai's idea could be realized, then the heat would be great.
The threshold for the spraying process will be significantly lowered, the price of the equipment will be two orders of magnitude lower than now, and the cost of spraying will be reduced to a popular level.
Once the thermal spraying process becomes simple and cheap, the application of this technology will become very common. The field of agricultural machinery and tools is only a very small market for it, and it will be widely used in fields such as mining machinery, hardware tools and even the military.
By using this process to improve product performance, the value of this market will not be the tens of millions Qin Hai said, but may reach hundreds of millions or even billions...
No wonder Qin Hai is so serious about this matter. With such a promising technology, no one will be indifferent if it is placed in their hands.
Seeing the surprised expression on Li Linguang's face, Qin Hai knew what he was thinking. He smiled and said: "Haha, Teacher Li, this is just an idea. To realize it, I may have to ask you to come out.
Woolen cloth."
This is not a modest statement. Although Qin Hai understands the technical know-how of the entire thermal spraying process, to truly turn it into an operational technology, a lot of experiments are needed, such as the temperature of the flame, the speed of the air flow, the nitrogen
The size of the titanium particles, etc., all need to be determined after the experiment. If Qin Hai is given enough time and enough assistants, he can organize such an experiment himself, but he has to do more than
In this regard, with a great helper like Li Linguang in front of him, why wouldn't he use it?
"This is quite interesting. I've accepted this task." Li Linguang didn't have any extra courtesy and directly agreed to Qin Hai's request. However, to do these experiments, it was not enough to rely on him as a material expert. The design of the spray gun
And manufacturing is not something he is good at, so he quickly emphasized: "In this matter, Professor Yue Kun from the Department of Mechanical Engineering must be invited to participate. The design of this spray gun is not a simple matter. Lao Yue is an expert in this aspect."
Expert. In addition, after designing the spray gun, you still have to find a factory to produce it."
Qin Hai had also thought about this issue. He said, "I'll leave it to you, Teacher Li, to ask Professor Yue. In terms of fees, how much do you think should be appropriate?"
Li Linguang waved his hand and cursed angrily: "I've never left my profession. Do you think Lao Yue came to help because he liked the money you gave me?"
Qin Hai quickly said with a smile: "I know, I know, but you have to pay someone to do things, otherwise my conscience will be uneasy, right? How about this, Teacher Li, ask Professor Yue to help, every month
Calculated based on a remuneration of 500 yuan. If he brings students to help, no matter how many students there are, it will be 100 yuan per person per month, what do you think?"
"Okay, then I'll 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 helped Pingyuan Iron and Steel Plant, Qin Hai paid him higher than this.
, and he was used to it. Although he said that Yue Kun didn't care about remuneration, Qin Hai could give him some remuneration, so it would be easier for him to talk to Yue Kun about this matter.
Qin Hai continued: "As for the production of spray guns, just leave it to Qingfeng Factory. Qingfeng Factory itself is a machinery factory, and there are no big difficulties in ordinary machining. If you encounter higher-precision processing tasks, you can ask
Factory Director Ning seeks help from other companies, and his options are very broad."
"Okay, then it's settled." Li Linguang said.
"In terms of funds, I asked Song Hongxuan to allocate 200,000 to you first. If it is not enough, you can always tell Xiao Song what do you think?" Qin Hai said again.
"How can we use so much money?" Li Linguang said subconsciously. 200,000 yuan was a huge sum of money in those days. Li Linguang couldn't think of anything that would cost so much money to conduct a research.
Qin Hai didn't bother to explain too much to Li Linguang. He knew that although he had mapped out the key paths, Li Linguang would need to spend countless manpower and financial resources to complete this research. Take thermal spraying.
For spray guns, the materials 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. The trial production cost alone is probably not enough, which is only 200,000.
Li Linguang also stayed in a small temple like Anhe Institute of Technology for too long and lacked experience in undertaking large-scale scientific research tasks, so he did not have a direct sense of funding.
"Teacher Li, please don't worry about how much money you have. My current requirement is that, at any cost, the technology and equipment must be completed within 2 months, so that we can catch up with the Farming Equipment Expo in 3 months. You
Can it be done?" Qin Hai asked.
Li Linguang said: "The 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 to transfer 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 bringing glory to the country."
"Well, this slogan is indeed more appropriate." Qin Hai smiled. Although the saying "all about money" has become popular in society, sometimes some political slogans are more effective in schools.
can at least satisfy the school. Qin Hai speculated based on his own experience that if the overtime pay for students and teachers is sufficient, coupled with the political honor after winning the international award, it should be enough to make everyone work day and night.
Already.
With Li Linguang's ability, he is relatively confident that he can come up with a set of thermal spray equipment that can basically meet his needs in two months. Qin Hai has enough confidence in this "sweeping monk".
"By the way, Mr. Li, one last thing to add. The authorship rights for the papers produced in this process belong to you. You can publish them. I only need the final patented technology." Qin Hai said lightly.
