When titanium tube forming process parameters on the factors of porous materials are size, size distribution, pressure and so on. If you want the system to take a large aperture and high permeability of porous material, should use a large powder grain size; and vice versa. The porous material should use a narrow particle size distribution of the powder, which is due to the presence of arch effect, will increase the porosity. Porous materials such as the use of spherical powder, to improve the permeability is advantageous. Pressure on the molding process parameters influence. With the molding pressure increases, the article porosity and permeability decreases.
When
Powder coating titanium forming process parameters influencing factors dense material has a particle size, size distribution, pressure and so on. In contrast with the porous material, preparation of the selection process of the mixed powder, namely a broad particle size distribution of powder compaction as well, often used in less than 150um (100 mesh) size fraction of the powder. Such fine powder easily pressed into the coarse pore, when pressed compacts dense, high bulk density. If the powder particle surface uneven, more angular, for repression is beneficial. Pressure forming impact, but the impact is not very significant. As the pressure increases, the beneficial increased denseness products, reduce the product porosity.
Sensor Titanium housing is a loose powder or sintered compacts at high temperature by metallurgical bonding process to form a dense or porous articles. Sintering the powder particles to achieve strong binding body, and the mixed powder is alloyed. Typically the sintering temperature is lower than the melting point of the main component.
