Hearing Qin Hai say so solemnly, Li Linguang smiled. He never thought about what patented technology he wanted to have, it was his interest to engage in scientific research, and patents were not patented, which did not mean anything to him. In the past two years, he has done some things for Pingyuan Special Steel Factory, and Qin Hai has paid him handsomely every time, which has made him feel a little uncomfortable. What Qin Hai is talking about now is, in his opinion, just a new research task, and it doesn't matter whether he gives money or not, let alone the ownership of patents.

"Xiao Qin, what idea makes you so cautious? Before you even get started, you need to think about patents first. Li Linguang asked.

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

"I don't even want it." Li Lin said with a grin, "I have a salary, what do I want you to do?" Xiao Qin, you are used to being a capitalist now, and you only think about money in everything. ”

Qin Hai Zhengse said: "It's really a big deal about this technology, if you can make it, the market value of a year will not be less than 10 million." Two achievements are not less than 2 million ...... Mr. Li, you really don't care? ”

"Not less than 10 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, and couldn't help but look stern, he asked, "Xiao Qin, what kind of technique is it, you actually have so much confidence?" ”

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

Li Linguang thought for a while and said: "The Vickers hardness of titanium nitride can reach more than 2,500 at the highest level, and the melting point is close to 3,000 degrees Celsius. It is indeed a suitable material for making high-wear-resistant tools. But how do you plan to attach it to a metal surface? ”

Qin Haidao: "The traditional method will definitely not work. This time when I was in Beijing, I read some foreign materials and found that the current foreign spraying process is progressing very fast, can we use this method to coat titanium nitride particles on the metal? ”

"You're talking about the spraying process? I've read the literature on that as well. However, the spraying method requires a high-energy, high-speed plasma generator, the cost of this equipment is not what we can imagine, used to make agricultural tools, is it a bit of an anti-aircraft gun to fight mosquitoes? Li Linguang reminded.

Qin Hai smiled slightly and said, "That's where my idea comes from. Mr. Li, think about it, if we don't use plasma equipment, but use ordinary flame spray guns to generate high-speed particles. Is it possible to make it impact on the metal surface to produce a spraying effect? You see, here's what I'm envisioning......"

Speaking of 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 nothing more than the high-speed flamespray gun that had become very popular in later generations, and its principle was very simple: oxygen and fuel were sent into a closed cavity to burn and expand. Then a nozzle is ejected. The sprayed material is fed into the nozzle through another opening, so that the high-velocity gas carries the material to the surface of the substrate. Achieve the effect of spraying.

Among them, of course, there are many key technical details involved, which still plagued materials scientists around the world back then, but for a traverser like Qin Hai, it is very simple knowledge. He mentioned a few words to Li Linguang, and Li Linguang nodded. His face gradually became filled with excitement.

"That's right, that's right, this idea should be right!" Li Linguang couldn't help but praise in a lost voice, "Xiao Qin, how did you have such a brain, how could you think of this method?" ”

As a connoisseur of materials. Li Linguang could hear the feasibility of Qin Hai's proposal. Although this is only a hypothesis, it is not far from reality. He knew that if Qin Hai's idea could be realized, the threshold of the thermal spraying process would be greatly reduced, the price of the equipment would be two orders of magnitude lower than the current one, and the cost of spraying would be as low as the popular process.

Once the thermal spray process became simple and inexpensive, the use of this technology became commonplace. The field of agricultural machinery is only a very small market, such as mining machinery, hardware tools and even military fields, will apply a large number of this process to improve product performance, then the value of this market is not Qin Hai said tens of millions, but may reach hundreds of millions or even billions......

No wonder Qin Hai is so serious about this matter, a technology with such a future will not be indifferent to anyone's hands.

Seeing the surprised expression on Li Linguang's face, Qin Hai knew what he was thinking, he smiled hehehe, and said, "Hehe, Teacher Li, this is just an idea, and if you want to realize it, you may have to go out of the mountain." ”

This is not a modest remark, although Qin Hai understands the technical know-how of the entire thermal spraying process, but to really turn it into an operational technology, a large number of realizations are required, such as the temperature of the flame, the speed of the air flow, the size of the titanium nitride particles, etc., all need to be determined after the realization. If Qin Hai was given enough time and enough assistants, he would be able to organize such a reality himself, but he had more than that, with a god-level helper like Li Linguang in front of him, why didn't he use it?

"It's a lot of fun, and I've taken over this task." Li Linguang didn't have any extra politeness, and directly agreed to Qin Hai's request. However, to do these things, it is not enough for him to be a material expert, and the design and manufacture of spray guns is not something he is good at, so he quickly emphasized: "In this matter, we have to invite Professor Yue Kun of the Department of Mechanical Engineering to participate, the design of this spray gun is not a simple matter, Lao Yue is an expert in this area." In addition, the design of the spray gun has to find a factory to produce it. ”

Qin Hai had also thought about this question, and he said, "Please leave the matter of Professor Yue to you, Teacher Li." In terms of cost, how much do you think should be appropriate? ”

Li Linguang waved his hand and scolded angrily: "Three sentences do not leave the bank, do you think Lao Yue came to help because he took a fancy to the money you gave?" ”

Qin Hai hurriedly said with a smile: "I know, I know, but if you ask someone to do something, you have to pay for it, or my conscience will not be at ease, right?" In this way, Mr. Li, please ask Professor Yue to help, and the remuneration will be calculated at 500 yuan per month. If he brings students to help, no matter how many students there are, 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, he helped Pingyuan Iron and Steel Factory, and Qin Hai paid him more than this, and he was used to it. Although he said that Yue Kun would not care about the reward, Qin Hai could give some compensation, and it would be better for him to talk to Yue Kun about this matter.

Qin Hai continued: "As for the production of spray guns, it can be handed over to the Qingfeng Factory. The Blue Point factory itself is a machine factory, and there is no major difficulty in ordinary machining. If you encounter a processing task with higher precision, you can ask Director Ning to find other companies to assist, his path is very wide. ”

"Okay, that's it." Li Linguang said.

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

"Why do you need so much money?" Li Linguang subconsciously said that 200,000 yuan was a huge amount of money back then, and Li Linguang couldn't think of what he needed to spend so much money on to conduct a research.

Qin Hai didn't bother to explain too much to Li Linguang, he knew that although he had depicted the critical path, the manpower and financial resources that Li Linguang needed to complete this research were incalculable. For example, spray guns used in thermal spraying must meet the requirements of high temperature and high pressure, which is very expensive. To finalize the design, I don't know how many versions I need to design, and the trial production cost alone is probably not enough for 200,000 yuan.

Li Linguang has also stayed in a small temple like Anhe Institute of Technology for too long, and lacks experience in undertaking large-scale scientific research tasks, so he does not have a direct sense of funding.

"Teacher Li, don't worry about the money and the money. My current requirement is that at all costs, the process and equipment must be out within 2 months, so that we can catch up with the Farming Equipment Expo in 3 months, can you do it? 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'm going to go to Lao Yue tonight and mobilize the graduate students of their department and the graduate students of our department, and everyone will work overtime, after all, this is also a matter of winning glory for the country. ”

"Well, that's a bit more appropriate." Qin Hai smiled, although the saying "one qiē looks at money" has become popular in society, in the school, sometimes some political slogans are still more effective, at least to make the school satisfied. Based on his own experience, Qin Hai speculated that if the overtime pay for students and teachers was sufficient, coupled with the political honor after winning the international award, it should be enough for everyone to work without sleep and food.

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

"That's right, Mr. Li, and one more thing to add. The authorship of the papers produced in this process belongs to you, and you can use them for publication. I just need the final patented technology. Qin Hai understated that he promised Li Linguang a great benefit. (To be continued......)
