Problems solved by technology

[0004] When using metal powder to prepare porous filter material, because the metal powder is completely connected by sintering, and because of the porosity, the finished filter element is relatively brittle, and the overall strength is not high. In the case of fragmentation, in order to ensure the strength during use, the porosity and pore density of the material are usually selectively reduced, but the reduction of the pore density will inevitably affect the filtering effect of the filter element

Abstract

The invention discloses metal powder hole-adding and reinforcing type sintering equipment, and belongs to the technical field of sintering. By using the metal powder hole-adding and reinforcing type sintering equipment, not only the porosity density in a sintered product can be increased in terms of the cycle of an inert gas when sintering, but also nanoscale high temperature ceramic particles canbe transported into a metal powder plate and adhered to the hole wall inside the metal powder plate. At the same time, with the function of a hole-adding and reinforcing chain embedded in the metal powder plate, the porosity can be further increased at the one hand in the process of degradation products overflowing upward when sintering, and on the other hand, high temperature silicon carbide fiber particles will scatter during the bursting so as to be adhered to adjacent pore inner walls. The dual function of the nanoscale high temperature ceramic particles and high temperature silicon carbide fiber particles can obviously increase the strength of the pore inner walls, improves the material strength of the finished product obtained by the sintering, and reduces accidental breakage whileimproving the filter effect of a filter element prepared by using the material.

Description

technical field [0001] The invention relates to the technical field of sintering, in particular to a metal powder hole-reinforced sintering equipment. Background technique [0002] Metal powder sintering refers to the use of infrared lasers to instantly heat various metal powders to a molten state and shape them. This technology was developed and researched as a rapid prototyping (RP) technology at the beginning, but with the maturity and application of the technology, it was found that the metal powder sintering equipment can be used as a new generation of low-carbon rapid manufacturing equipment. Several industries have used this technology as a new generation of manufacturing equipment. [0003] The sintered metal powder filter element is made of metal powder as raw material, without adding binder, and is made by high-temperature vacuum sintering after cold isostatic pressing. The pore size and distribution of the component can be adjusted by selecting the particle size...
