Master descends to earth

Chapter 89 Technology Invasion
Satisfied, Su Yuan succeeded in stealing his teacher, and he knows the craftsmanship of Damascus knives by heart, so this trip was worthwhile.

Huangfu Jiang said with a smile: "These are the things I liked the most when I first started collecting. At that time, I didn't understand much. I just followed the trend and echoed what others said. Fortunately, I bought it early and the price is cheap. If I change it now, I can change it for a few. A Mercedes."

Shen Huanwen frowned, as if thinking of something, and said: "Hmph, if you can buy a genuine handmade product, you're lucky. Many of the Damascus products on the market are fake. They are either pickled or powder metallurgy. They are all profiteers!"

Su Yuan nodded. When it comes to industrial forging technology, he is an expert. After all, he came from a four-year university and is very familiar with high technology.

If you identify Damascus knives purely by patterns, you will definitely make holes. In the early years, there was a method of counterfeiting Damascus knives called etching patterns, which was to use strong acid to etch patterns on a single steel. This is completely different from the pickling process of real Damascus knives.

Later, a more powerful new technology appeared, Ruifen, a Swedish powder metallurgy technology.First, in a high-temperature vacuum environment, the molten steel of two or more materials is sprayed into mist-like powder.

Then use a computer to control the arrangement of these powders to form various patterns you want, and then cool down to condense these misty powders into small steel balls, and then use high pressure to melt and press the steel balls into a steel base plate.Its patterns are regular and neat, and can be designed into any pattern.

In terms of hardness, Swiss powder is comparable to folded and forged Damascus steel, but the steel formed by condensing powder is far inferior to folded and forged Damascus steel in terms of toughness.

Huangfu Jiang turned around and took out a piece of steel from the cabinet, showing it: "This is the representative of American Thomas hand-forged stainless Damascus steel. It is famous for its excellent performance, low-key and rigorous pattern. Users include the world's top knife company William Henry , old-fashioned pocket knife Kath, and top craftsmen such as Chris Reeve."

Reluctantly said: "Now that high technology is rampant, manual forging not only takes a long time, but also consumes a lot of energy, and it cannot be mass-produced at all. The world's top cutting tool companies spend hundreds of millions of dollars every year to research new technologies. billions of profits."

Su Yuan walked to the display cabinet next to him. There were dozens of kinds of military knives inside. To put it bluntly, playing with military knives is about making steel. A large number of high technologies continuously improve the strength and toughness of the raw materials. Coupled with fine grinding by computers, the efficiency is countless times higher than manual work.

Among other things, there are at least five ways to deal with the surface of the blade.Examples include anodizing, an electroless surface covering treatment that can change the appearance of a product and improve surface color and texture.

The most common is the anodized surface treatment of titanium and aluminum.Different colors can be produced by using different voltages, and many colorful knives on the market come from this.

For military knives, bead blasting is more widely used, and the high-pressure cleaning of the surface is much less damaging than ordinary sandblasting, and the treatment cost is relatively low.Often used in tactical folding knives and straight handle knives, it is characterized by a 100% dull surface on the knife, completely eliminating reflections.

In the dark night, kill people invisible!

There is also black oxidation technology, especially black titanium carbon treatment. The surface is coated with a black coating of titanium carbon material with a thickness of only 3 microns, which can not only eliminate reflection, but also enhance its corrosion resistance.

After the surface of the tool is coated, the hardness and wear resistance of the tool surface and the cutting performance of the tool can be improved, so the service life of the tool can also be extended.

The most powerful thing is the newly emerged BM technology, a black Teflon coating treatment method.It is 40 times higher than the current standard for corrosion resistance of stainless steel.

At the same time, Teflon also improves the cutting ability of the knife. The coating has a fine structure, and pressure will be generated inside the coating, so the ability to resist crack expansion is stronger.

As for the types of high-tech improved steel materials, there are at least dozens of mainstream types, and each large company has its own main characteristics.After cold weapons withdrew from the war arena, they were turned to civilian use, mainly sabers.

"In a few days, the World Saber Expo will be held every year. It is the top event for knife companies to showcase new technologies."

Huangfu Jiang said with a smile: "Brother, if you have time, let's go see together?"

Su Yuan readily agreed, thinking of the system's tricky mission, the World Saber Expo... a bit interesting!
Shen Huanwen also nodded in agreement. He had been there a few times in the early years, and each time he came back angrily.

After watching all the swords and swords, Su Yuan was very satisfied, and frantically collected a lot of experience points, especially in other categories, and his level improved a lot again.

Shen Huanwen suddenly remembered something, and asked, "I haven't been here for ten years, are the old rules still in place?"

Huangfu Jiang laughed loudly, and said to himself: "It's not unreasonable to have friends coming from afar. Wanjian Villa naturally treats each other with courtesy, let alone a master like Brother Su, please come with me."

Seeing Su Yuan's puzzled expression, Shen Huanwen explained in a low voice: "What I saw just now was only one-tenth of the old guy's collection. Wanjian Villa is indeed not in vain. Don't be too polite, just pick the best!"

Soon everyone came to the second basement floor, which was full of shelves, densely packed with thousands of swords of all kinds.Huangfu Jiang said proudly: "This is the rule of Wanjian Villa. Whenever a distinguished guest comes to the door, he can choose a sword he likes and take it away. It can be regarded as a meeting gift for old people."

"Hmph, show off your stink!" Shen Huanwen scolded with a smile, but his body was very honest, and he started to choose without saying a word.

Su Yuan was overjoyed. He had never seen the spectacular scene of thousands of swords. Most of them were collected by Huangfu Jiang in his early years. Many of them were rusty ancient swords. There were too many of them, and he didn't have the time and energy to re-polish them.

Huangfu Jiang said with a smile: "You're welcome, brother. Many sword prototypes came from here when Mr. Xu took pictures of Mount Shu. Later, he simply asked his friends to choose, and it was a kindness to bring them back."

Su Yuan laughed, if that's the case, then what are you waiting for?
All kinds of lights flickered in his eyes, and he quickly walked among the shelves. Suddenly, his eyes lit up, and he hurried to the corner and took out a large bundle of ancient swords.

The surface was stained with rust, but Su Yuan felt like he had found a treasure, the golden lightsaber, it was actually a golden lightsaber!

Soon, Shen Huanwen and Xu Kui also found their favorite swords, both of which were ancient swords. Shen Huanwen specially picked a Qin bronze sword, which can be regarded as a collection and research. This kind of museum-level thing is not easy to find.

Huangfu Jiang waved his hand. He looked like a rich and powerful local tyrant. He had made an inventory and collected more than [-] of them. Ninety percent of them were ancient swords. Instead of rusting in his own hands, it is better to give them to those who are destined to live.

Everyone chatted happily, and didn't leave until night to go back to the hotel. After Su Yuan polished it briefly, he looked at the golden light sword, and a thought flashed in his mind...
