"This kind of ultrasonic impact strengthening is actually not too suitable for our use, the biggest use of this technology is in the place where there are a lot of weldments, it can have a very good strengthening effect on the weldment joints of the weldments, GM provides this technology for us is not bad, although his biggest use is used in welded parts, but it also has a good strengthening effect on ordinary metals, and our engines also have a lot of welds, and it is necessary to use this process at that time."

Mr. Wu still has a lot of ideas about this technology, although this technology is not as obvious as the special metal spraying to improve the life, but the advantage is that the application of this technology is wide, and the compressor and stator manufacturing of aero engines are no longer the mortise and tenon structure used in the core machine of the current push.

The compressor and stator ring manufactured by integrated welding are the king, and although the welding technology of these compressors and stator rings is very high-end, such as electron beam welding, friction welding, etc.,

The technology sounds higher than the other, but as long as the welded components will have welds, these welds need to use ultrasonic impact strengthening, which is absolutely unavoidable, and it can be said that it will not suffer if you get this technology.

Mr. Wu was afraid that Yang Hui would feel uncomfortable after knowing that GM had replaced the special surface metal spraying technology with ultrasonic impact strengthening, and that it would be a trivial matter to be unhappy with GM at that time, and he was afraid that Yang Hui would be unhappy with the 624 Institute, and that his good life in the 624 Institute would come to an end after only a few days, which was absolutely not good.

After explaining the application prospect of this ultrasonic impact strengthening technology, Chief Engineer Wu told Yang Hui about the current status of the old-fashioned metal strengthening technology in China.

"The metal strengthening process we use now, in addition to the surface heat treatment, the physical treatment process, that is, the surface shot peening strengthening process, is an old technology developed in the forties, although later there was a sandblasting process. However, we are still lagging behind in all aspects, and we need to take this opportunity to upgrade our metal finishing process. ”

Hearing this, Yang Hui did not have such an expression, but a kind of sudden realization, just now after hearing the ultrasonic impact surface reinforcement treatment, Yang Hui always felt familiar. Now after hearing the shot blasting enhancement, I finally remembered what I just thought was familiar.

In fact, Yang Hui is not only familiar with the ultrasonic impact strengthening process, this technology is not very common in the aviation industry of the previous republic, but it is more used in the Russian aviation industry, and the republic is only used in some processing equipment of this technology introduced by Russia.

Yang Hui is also familiar with another technology, which is the fusion product of ultrasonic impact strengthening and shot peening impact strengthening treatment technology that was used on a large scale in the world in the 21st century, which is called ultrasonic shot peening.

This kind of ultrasonic shot peening strengthening technology, strictly speaking, can not be regarded as the improvement of ultrasonic impact strengthening, this metal strengthening technology and ultrasonic impact strengthening is very different, one is to strengthen the inside of the metal. One is surface strengthening.

The working medium of ultrasonic shot peening is actually the ejected pellet, sand particles, etc., and ultrasonic is only a medium that drives the pellet body and sand particles, and the two technologies are absolutely different from each other.

Since this technology relies on shot peening and metal impact to complete the strengthening, the strengthening effect of this technology is more like the effect of shot peening, the difference lies in the various benefits brought by the medium that drives the pellet body and sand particles.

Speaking of this technology, it is still very valuable, at least much better than the traditional shot peening, and the most in-depth study of this technology is the French, the last French began to work on the one side in 96. In 2000, the equipment was put into operation.

Subsequently, this equipment was purchased in large quantities by the French group Safran, which manufactures the CFM-56 engine. It was used in large quantities in the manufacture of aero engines in France, and subsequently in various aircraft factories and used in the aerospace sector.

After the year 2000, it was widely heard that the use of tall laser shocks to strengthen various metals in the aerospace system of the Republic was widely heard, which greatly increased the service life of the Republic's aircraft, engines and other industrial equipment.

This is indeed a fact, the Republic of China's 863 plan focuses on lighting up the laser technology tree, and naturally the Republic has a huge advantage in laser impact enhancement.

But this kind of thing is not a panacea. First of all, energy consumption is a bit unbearable, as we all know, energy consumption is one of the obstacles to the large-scale use of lasers.

It can be said that the Republic did use laser impact to strengthen some key components and equipment of aerospace equipment in the previous place, but due to cost, there is still no way to strengthen laser impact on many parts.

Don't say anything about military equipment regardless of the cost. It is completely impossible to say anything regardless of the cost when purchasing in large quantities, and even a local tyrant like the US imperialist does not dare to play like this with all the equipment.

In order to manufacture excellent aerospace equipment at the lowest possible cost, there must not only be high-end things like laser impact strengthening, but also slightly low-end metal strengthening equipment, and this kind of ultrasonic shot peening equipment is definitely the best choice.

After the Republic has started the 863 Plan, Yang Hui does not care about the Republic in the field of laser processing and manufacturing in the future, as long as there is a need, what laser sintering, 3D metal printing, laser impact strengthening is a matter of minutes.

Yang Hui now just needs to consider the problem of low-end metal strong light equipment in the aerospace manufacturing field in the future, and this ultrasonic shot peening technology is a good choice.

Of course, this kind of ultrasonic shot peening strengthening is indeed very good, in the field of aerospace such a perverted processing and manufacturing is indeed a low-end technology to be used on a large scale, but after it is put on the market in the future, it is definitely a metal strengthening equipment that is a bull, and this kind of thing is definitely a treasure of the town when used as cutting-edge equipment in the ordinary metal processing field.

That is to say, ultrasonic shot peening strengthening is more accessible to the people than laser impact strengthening, and the market is broad in the future, and the ultrasonic shot peening strengthening equipment in the previous surface is monopolized by the French, and there is no rumor about the manufacture of this equipment in the republic, which has to be said to be a mistake.

Now that the ultrasonic impact strengthening equipment has been introduced, Yang Huier is willing to mention the units in the Republic that have the strength to manufacture shot peening equipment, and win the patent and manufacturing technology of this equipment before the French, which can be regarded as a happy thing at that time.

Thinking of this, Yang Hui no longer hesitated, nodded and affirmed what Chief Master Wu said, and then shifted his attention to the data of this core machine again.

On the third day after arriving at the 624 Institute, the turbofan 10A engine was installed in the high-altitude cabin, and Yang Hui was finally relieved to see the beautiful and fashionable tail nozzle of this engine.

To have such a good engine, although it will not be able to give the JF-17 fighter under development more surplus thrust and reach the level of perverted US imperialism, but at least the engine will not be a drag on the aircraft. (To be continued.) )
