Tag Powder Metallurgy process

Powder metallurgy is an emerging technology, but also an ancient one. According to archaeological data, as far back as 3000 years ago, the Egyptians in a kind of bellows with carbon reduction of iron oxide to get sponge iron, high-temperature forging made of dense block, and then hammered it into the iron device. 3 century, India’s blacksmiths with this method to make the “Delhi column”, weighing 6.5t.

In the early 19th century, in Russia and the United Kingdom platinum powder was by cold pressing, sintering, and then hot forging dense platinum, and processed into platinum products process.

In the 1850s appeared after the platinum smelting method, the powder metallurgy process will stop applying, but it is the modern powder metallurgy process laid a good foundation. Powder metallurgy did not develop rapidly until 1909 when Coolidge’s tungsten filament for electric lamps was introduced.

What is powder metallurgy?

Powder metallurgy is the production of metal powder or metal powder (or a mixture of metal powder and non-metallic powder) as raw materials, through molding and sintering, the manufacture of metal materials, composite materials, and various types of product process technology.

The powder metallurgy method and the production of ceramics have similarities, both belong to the powder sintering technology, therefore, a series of new powder metallurgy technology can also be used for the preparation of ceramic materials.

The use of powder metallurgy technology can be directly made of porous, semi-dense, or fully dense materials and products, such as oil-bearing bearings, gears, cams, guide rods, cutting tools, etc., is a less cutting-free process. Due to the advantages of powder metallurgy technology, it has become the key to solving the problem of new materials and plays a pivotal role in the development of new materials.

Exploring the Power of Powder Metallurgy

Powder metallurgy (PM) encompasses various methods for creating materials or components using metal powders. By employing PM processes, the reliance on subtractive manufacturing techniques can be minimized or eliminated altogether. This not only decreases material waste but also leads to…
