This kind of indium is really very widely used, not only on the turbine blades of our aircraft engines.

It can also be used in combustion chambers and other places that need to withstand high temperatures.

The high temperature and creep resistance of this thing is naturally supported by those alloy components.

So with this rare metal, we will definitely make major breakthroughs in smelting some special high-temperature-resistant components in the future.

The two even estimated that with this metal, the aircraft engine life of our fighter jets could be at least doubled.

You know, in fact, we were stuck in the material before.

We didn’t have rhenium before, so the turbine blades could not be created at all.

Even if it can be made, it will not be resistant to use.

Later we had rhenium, and the titanium alloy blades could be made.

But even if you can come out early, you will only reach the level of a hairy bear, and you will not even be as good as a hairy bear.

What does it mean?

In fact, when it reaches the point of doing aviation engines, the effect of finishing is not so obvious.

The amount can only affect the speed of aeroengine manufacturing and processing and the stability during use.

As for the lifespan of aircraft engines, this is still a stumbling block in front of our national defense and military industry departments.

Because if you want to solve the life of aeroengine, you must solve the material problem.

And this is exactly what the Americans are best at, and it is also the weakest place for us and the bears.

However, other bears have always been rich and do not care much about the lifespan of aircraft engines.

Why?

Because they are the largest titanium producer in the world, they have been playing with titanium alloys for decades.

It can even be said that it is the best one to play with titanium alloy in the world.

Although they usually say that our aircraft engines are very expensive, they can't afford to use their own air force.

That's just a normal day. If it comes to wartime economic situations, people can be infinitely violent.

No cost is considered.

So aeroengine can build as much as you want, and although the life of an aircraft engine is only 3,000 hours.

But people do not pursue the idea that it takes 30,000 hours like the Americans.

Because in Mao Xiong's opinion, when fighter jets solve combat in the air, they are often done in an instant.

So why do you make aircraft engines so durable?

30,000 hours, can you use it?

A battle often ends in just a few seconds. Is it useful to build an aircraft that can fly 30,000 hours?

Of course this is the design concept of the bear.

The American side has a completely different idea because they are world policemen.

There are many military bases in Quanqi, so people must ensure their own military deployment.

So their requirements for aircraft are not only to fly far, but also to be durable, so they pay great attention to economics.

After all, they have a large number of equipment, and they only have hundreds or thousands of them at any time.

If they all fly like Mao Xiong's plane, they will have to change the engine after three thousand hours. Even if the Eagle Sauce is rich and powerful, they will not be able to afford it.

When we make aircraft engines, we first learned bears, but the problem is that we are very similar to learning from the United States.

After all, American aircraft and aircraft engines pay attention to economics, and we are relatively poor, so naturally the longer the aircraft is, the better.

But the problem is, we can't learn other people's skills!

Even if you understand a series of knowledge about processing and aerodynamics.

But the problem is that you can't learn the materials used by other people's planes!

For example, the earliest aircraft engines of Eagle sauce were combustion chambers and turbine blades made of indium rhenium titanium alloy.

Now the technology has been further upgraded, using blades made of carbon nanometer-compliant materials.

However, they still use indium alloy for the combustion chamber.

And even if we know, we can't learn it.

Why?

Because we have very little indium, the United States is very strict in the control of import and export of this metal and international transactions.

Back then, one rhenium stuck us to death, let alone such a sensitive rare metal.

And now that we have found here, we finally don’t have to worry about indium.

And not only indium, but also palladium.

This palladium is also a very important rare metal.

This thing belongs to the metal element of the platinum family, mainly used to make medicines and plays a very important role in treating groundwater essence.

However, with the development of new energy, this thing has played another important role.

It's the essence of hydrogen...

You know, many countries are now secretly developing hydrogen energy.

Although the next generation of new energy has been defined as the era of electric vehicles.

But countries around the world have not stopped exploring the development of hydrogen energy.

Because everyone knows that hydrogen energy is the ultimate clean energy solution.

However, when it comes to refining hydrogen, everyone has many problems.

For example, the most important source of hydrogen is now produced by chemical cracking.

In this process, a large amount of gas will be generated, one of which is hydrogen.

However, hydrogen will be mixed with other gases, so how to separate hydrogen from other gases?

It has become the most troublesome problem for scientific workers.

After thinking about a lot of ways, everyone finally came up with a method, which is to use palladium.

Use this metal to react with hydrogen and then reduce it.

This is the lowest cost separation method at present.

However, palladium is a thing that has very little stock on land.

So the price is also very expensive. The current price of this thing is almost the same as gold.

It has reached 380 yuan per gram, which shows the rarity of this metal.

One of the reasons why we did not have a good way to produce hydrogen in large quantities in China was the lack of this rare metal.

Because the output is too small, the hydrogen production cannot be increased and the price cannot be reduced.

So we have no motivation to vigorously promote hydrogen.

However, after discovering this kind of palladium in large quantities, our hydrogen energy development can finally go further.

This is definitely good news, but for the Tianjing, that would be even better.

Because of this thing, they can also sell it at a good price.

Then there is scandium, which is also a very rare metal.

And the purpose of this thing is even more extensive.

It can be used to make aviation metals with aluminum alloys and magnesium alloys.

Because just adding a little of this element can greatly improve the hardness and toughness of the metal.

In addition, this metal also has very good resistance to neutron impact, which means it also has certain radiation resistance.

You said this thing is not expensive?
