Hand rubbing nuclear fusion live in the wilderness

Chapter 230 Titanium Aluminum Alloy
[I forgot to write the title name o_o, but it has already been sent out, I can’t change it, I’ll edit it tomorrow and go to work (●ˇˇ●)]

Rows of different containers are placed on the silver-white laboratory table in the chemical laboratory.

Inside is a metal ion electrolyte solution doped with metal powder, which is being connected in series for electrolysis at the moment.

The principle of electrolysis to prepare metal powder is actually very simple.

When a direct current is passed through an aqueous solution containing metal ions to be electrolyzed, an electrochemical reaction occurs in the electrolyte.

The metal cations in the aqueous solution will move to the cathode, eventually get electrons and be reduced, and then deposit at the cathode to become metal again.

As for the anode, it's either a rod of the same metal as the metal ions in the aqueous solution, or a rod of graphite.

Metal rods can continuously provide metal ions to the aqueous solution during electrolysis, while graphite rods can restore most of the metal ions due to their own characteristics.

The technological process of electrolytic purification of metals is very simple, and the purity of the produced products is also high, because only a single metal is deposited on the cathode during electrolysis, and impurities will be removed.

It's just that the electrolysis method consumes a lot of power, the production efficiency is relatively low, the cost is high, and it pollutes the environment, so the industrial application in modern society is much less than other methods.

It is precisely because of the high power consumption that the power supply provided by the chemical laboratory is no longer the sulfuric acid battery prepared before, but the electricity generated by the generator.

The alternating current generated by the generator can be converted into direct current after passing through a set of rectifiers, so as to continuously provide electric energy to the electrolyte.

The process of electrolytically purifying metals takes a long time. After the Korean Won has processed all the container equipment, he no longer cares about it.

As long as the power supply is continuous, there will be no problems under normal circumstances.

During this period, more and more single metals will be deposited on the cathode until all the metal ions in the electrolyte are consumed.

Even if the metal ions are exhausted, there will be no other things besides wasting electricity when the electricity is turned on, so Won can deal with other things with peace of mind.

Of course, some particularly active metals, such as magnesium and sodium, will not work.

Let alone whether it can be electrolytically reduced, even if it is possible, these metals will react with the water generated in the electrolytic waste and some other reactive liquids.

At that time, if you don't cut off the power in time, it will react again and cause the electrolyzed metal to dissolve, or it will explode and send you to heaven.

After dealing with the electrolytically purified metal in the chemical laboratory, Han Yuan took him to the door and went to the alloy smelter.

It was the room where the small smelting equipment was originally placed, but later he added some industrial equipment to the room, and later changed the name to 'alloy smelting plant'.

After all, the further back, the less the application of a single metal on various tools and equipment.

In many cases, a lot of equipment is basically made of alloys, and pure iron, copper, aluminum and other metals do not meet the requirements most of the time.

In the alloy smelting plant, various metal raw materials are piled up like hills on the ground.

There are titanium, aluminum, iron, copper and various rare metals.

These metals are all pieces of metal ingots, which were exchanged for Korean won from the mall, costing him thousands of technology points.

Fortunately, there are a lot of technology points left over from before, and he didn't use them much.

Han Yuan feels that the third-level and fourth-level tasks should be the tasks that consume the most technology points for him.

On the contrary, after taking the fifth-level mission, after getting the artificial intelligence and robots out, the consumption of technology points will be much less.

Because most of the raw materials can be mined and refined, and finished products can also be produced through the assembly line.

There is no need to exchange these things, and the consumption of technology points will naturally be reduced a lot.

But who knows what will happen in the future?
Maybe he died in the third-level mission, and it is also possible in the fourth-level mission.

In the alloy smelting plant, pieces of metal ingots are weighed according to the alloy ratio, and then put into small smelting equipment.

A series of steps such as inserting the forming agent, sintering, removing the forming agent, pouring into the mold, cooling and forming, forging, annealing, quenching, crystallization, and stress release are extremely cumbersome.

More importantly, many steps have to be carried out in vacuum electric melting, otherwise it will affect the performance of the finished alloy.

Busy until after ten o'clock in the evening, the first piece of titanium-aluminum alloy that can be used to make aircraft shells was produced.

The silver-white alloy plate shines brightly under the reflection of incandescent lamps.

The pressed alloy plate is very thin, only about [-] millimeters, and the width and length are a full two meters.

Although it is very thin, a titanium-aluminum alloy plate of this thickness is sufficient for the skin structure of the aircraft surface.

The skin on a fighter jet might be a centimeter to two centimeters.

But the surface skin of ordinary civil aviation airliners is a little thicker than this, at about [-]mm.

What's more, the aircraft he wants to build is not used for fighting or flying at supersonic speed.

The maximum speed is only [-] kilometers per hour, and the skin is so thick that it also affects the overall weight of the aircraft.

Reflecting the bright incandescent lamp, Han Yuan preliminarily inspected the surface of the titanium-aluminum alloy plate with his naked eyes.

The main thing is to look at the color of the finished product, and whether there are obvious signs of damage such as inclusions, holes and microcracks.

As for the specific test, we have to wait for the inspection with special instruments during the day tomorrow.

Properties such as strength, plasticity, toughness, formability, weldability, corrosion resistance, and biocompatibility all need to be checked one by one.

This is why South Korean Won chose to spend an afternoon to create a sample.

Only after this sample passes various tests can it be mass-produced.

This is a necessary testing step after any new material is developed.

Won does not allow any material that has not been tested and inspected to be installed on the aircraft.

It's okay if there are no problems, but if there is a problem, it will be catastrophic.

After a preliminary inspection of the titanium-aluminum alloy plate, Han Yuan returned to the chemical laboratory.

After more than ten hours of chemical electrolysis, the metals in each container have been refined.

The cathode filaments of the electrolytic vessel are covered with a thick layer of high-purity metal.

There are still some gray-black impurities quietly deposited at the bottom of some translucent electrolytes, some of which may be other metal powders, or impurities such as dust.

However, the purity of various metals attached to the electrolytic cathode filaments is quite good, and the purity is enough to make single crystal alloy materials.

After saving all the metal materials electrolyzed in the container, Han Yuan greeted the audience and started the live broadcast.

Today's live broadcast started at six o'clock in the morning, and it has been more than fourteen hours since ten o'clock in the evening.

However, apart from attracting the attention of many people in the morning, most of the audience left when the materials were processed in the afternoon.

Even experts and scientists from various countries have left a lot, leaving only some personnel from the replica laboratory to keep an eye on the live broadcast.

After all, it is very simple to purify materials and manufacture titanium-aluminum alloys.
