[Love Science] I know gold, silver, copper, iron and other metals [Love Science] I know gold, silver, copper, iron and other metals, but this is the first time I heard about titanium. What kind of metal is it? , but this is the first time I heard about titanium. What kind of metal is it?

Titanium’s unique life experience and basic properties

Titanium is a metal, its color is silver-white, very pure, and its melting point is very high, reaching 1668 degrees Celsius. Its core advantage lies in its extremely small density, only 57% of steel, but its strength and hardness are almost the same as steel. Compared with aluminum, titanium is not as light as aluminum, but its mechanical strength exceeds that of aluminum to a large extent. To sum up, titanium can have the two advantages of being as strong as steel and as light as aluminum.

In addition to being light and strong, titanium has good plasticity, good heat resistance, and good corrosion resistance. Since the 1950s, these characteristics have caused it to be widely used in the aircraft field, widely used in the rocket field, widely used in the missile field, and widely used in high-end manufacturing fields such as ships. In modern industry, titanium plays an increasingly important role.

The discovery of titanium took a long and tortuous journey

In 1795, the German chemist Klaplot discovered a new element in a red ore. He named it after the "Titans" in Greek mythology. The name was translated into Chinese as "titanium". However, what was found at that time was not metallic titanium, but powdered titanium dioxide.

It took more than 100 years from the discovery of titanium to the successful production of titanium metal. It was not until 1910 that American chemist Hunter produced titanium metal with a purity of 99.9% for the first time, but the total amount was less than 1 gram. This entire long process also clearly shows that the extraction and smelting of titanium is very difficult.

The magical uses of titanium dioxide and artificial fog

Titanium oxide is in the form of a very white powder, which is what we usually call "titanium dioxide". It is a high-quality raw material used to make coatings. Just 1 gram of titanium dioxide can paint a wall of 450 square centimeters as white as snow. Add it as a filler to paper pulp, and the paper produced is not only white but also opaque.

Titanium chloride, titanium tetrachloride, has a special purpose. The smoke it forms can last for a long time in the air. This is the so-called "artificial fog". This kind of artificial fog has applications in the military field and also in the performance field. It can achieve shielding effects and visual effects.

Piezoelectric and ultrasonic properties of barium titanate

Bulk barium titanate has unique piezoelectric properties. When pressure is applied to it, it can generate an electric current. Once it is energized, it will change its shape. This ability of bidirectional conversion makes it fully demonstrate its advantages in the field of sensors. If it is placed in an ultrasonic wave, the pressure of the ultrasonic wave will cause it to generate an electric current, which in turn can generate ultrasonic waves.

Relying on this property of barium titanate, scientific researchers have developed ocean detectors. This type of device can detect underwater fish schools, reefs, and enemy submarines. It has important applications in fisheries and military fields. Therefore, experts predict that after copper and iron, titanium will become the third largest metal in the future.

Discovery of the memory effect of nickel-titanium alloys

In 1961, researchers in the United States discovered the magical properties of nickel-titanium alloy during an accidental experiment. The nickel-titanium alloy wire that has been straightened will immediately return to its original curved shape when it is close to the fire. After many repeated experiments, this phenomenon can be repeated, which shows that the nickel-titanium alloy wire can remember and restore its original shape when the temperature increases.

For this phenomenon, the scientific people call it the shape memory effect. It turns out that metal actually has the ability to remember. An alloy like this that can remember its own shape has significant and significant uses in the manufacture of aerospace vehicles, automobiles, integrated circuits, and other objects, and even in the medical field, such as braces and braces.

Key applications of titanium in tool machining

Although titanium alloys are widely used in aerospace and medical fields due to their high strength and corrosion resistance, it is extremely difficult to process titanium alloys because of their poor thermal conductivity and low elastic modulus, which can easily lead to severe tool wear. Therefore, titanium alloy processing requires the use of special tools, and these tools are generally made of cemented carbide or cubic boron nitride materials.

The use of specialized cutting tools for titanium alloy processing can effectively reduce cutting temperatures and improve processing accuracy and tool life. For example, when processing aero-engine blades, the use of specially coated tools can increase the processing efficiency by 30% and extend the tool life by 2 times. For companies and engineers engaged in precision machining, choosing the right tool is the key to ensuring quality.
