The History Of Powder Metallurgy Беларусь

Because powder metallurgy is a new technology that is energy-saving, material-saving, efficient and time-saving, it can be widely used, from ordinary machinery manufacturing to precision instruments; from hardware tools to large-scale machinery; from electronics industry to motor manufacturing, powder metallurgy can be seen. The figure.

The history of powder metallurgy

1. Powder metallurgy originated in ancient times:

Powder metallurgy originated in ancient times, and the first method of making iron was essentially powder metallurgy. Because the metal does not reach melting during the production process, the iron ore is reduced by coke in the original furnace, the sponge iron sintered by the dispersed iron block is obtained, and the sponge iron is forged to make various instruments. With weapons.

2. In the middle of the 19th century, it was replaced by the casting method to be re-used:

With the development of metallurgical furnace technology, the metal powder metallurgy method was replaced by the smelting method in the middle of the 19th century. The metal powder metallurgy technology was re-used in the late 19th and early 20th centuries due to the development of electrical technology and required some materials. It is only possible to produce these materials on an industrial scale by metal powder metallurgy. Carbide articles have also appeared in the same period and used as a wire drawing die for drawing wires.

3. Widely used in the 1930s:

In the 1930s, metal powder metallurgy materials were widely used in the industry. Thanks to the use of friction metal materials, friction materials, filters, magnetic materials, contact materials, cutting tools, structural materials and other materials made by metal powder metallurgy, many technological fields have been made. In recent years, metal powder metallurgy materials have also been widely used in atomic energy and rocket technology.
