If you work in the powder sintering industry, here are 10 essential words for you to learn and understand. Let's learn together!
1. Powder metallurgy technology is widely used in transport, machine, technology, aerospace, weapon, biology, new energy, information, nuclear industry and other fields. It is one of the branches of the most dynamic branches of new material science. The statistics from CICC enterprise credit international consulting display: In 2017, the size of powder metallurgy products in China was about 7.15 billion yuan, up 7.84% year on year. The development of powder metallurgy is different day by day. It is necessary to understand the ten professional words if you want to have a basic understanding of powder metallurgy.
2. Powder sintering: Metal powder or powder billet, heated to a temperature below the melting point of the main components, due to the physical and chemical bonding between the particles, the required strength and characteristics of the material or product process.
3. Padding: A material in which a billet is buried for separation and protection during prefiring or sintering.
4. Powder metallurgy: A sintering process in which uniaxial pressure is applied simultaneously during sintering.
Powder size, particle composition: powder size is the size of powder particles. Particle composition also named particle distribution. It is the weight percentage of each grade of powder in the powder as a whole.
5. Relative density: The ratio of the density of a porous body to the density of the same constituent material in a non-porous state, expressed as a percentage.
6. Porosity: The ratio of the volume of all pores in a porous element to the total volume.
7. Sintering temperature: A series of physical and chemical reactions take place in the green body under the action of high temperature. Finally, when the apparent porosity is close to zero and the density reaches the maximum, this state is technically called "sintering", and the corresponding temperature when sintering is reached is called "sintering temperature".
8. Filtration accuracy: referred to as filtration degree, that is, the filtration efficiency with micron particle count.
9. Sieve mesh number: Mesh size is defined as the number of holes in an inch (25.4mm) length
10. Powder forming: Powder forming is the process of making powder into a blank with certain character, size, density and strength.
