Abstract
Provided is a method for processing and manufacturing a metal structural material by knitting metal wires into metal screen mesh strips, tightly coiling the metal screen mesh strips to form a coiled blank body which is coated layer-by-layer and in which an outer-layer material tightly covers an inner-layer material; sintering the coiled blank body; reducing gaps within the coiled blank body material by plastic processing to reach a porosity that fulfills requirements, and manufacturing mechanical structural parts therefrom.
Claims9
A method for processing and manufacturing a porous metal structural material comprising:
- firstly, knitting metal wires to form a metal screen mesh strip, and
- coiling the metal screen mesh strip to form a coiled blank body, an outer-layer material of the coiled blank body covers an inner-layer material of the coiled blank body;
- then, sintering the coiled blank body, and then
- plastic working the coiled blank body so as to reduce gaps and reach a porosity that fulfills requirements,
- manufacturing and obtaining the porous metal structural material, and
- manufacturing mechanical structural parts by using a mechanical processing method,
- wherein before the metal screen mesh strip is coiled, metal powder is evenly distributed on the metal screen mesh strip and the thickness of the metal powder is controlled to be uniform;
- then
- the metal powder is sintered;
- and then
- the metal powder is evenly coiled between layers of the metal screen mesh strip;
- and
- after sintering and plastic working the coiled blank body, a powder metallurgy porous metal structural material reinforced by the metal screen mesh strip is obtained.
