Sintered Perforated Titanium Plate Wastewater treatment

The porous material is a kind of structure-function integrated material. Due to the 

existence of pores, the specific surface of the material is increased and the density of the 

material is reduced so that the porous material has functional properties such as 

adsorption, filtration, noise reduction, and heat insulation. Its products are widely used in 

the fields of aerospace, medicine, environmental protection, metallurgy, and 

electrochemistry. The existing technology for preparing porous materials has 

complex processes, long production cycles, high technical requirements, and high cost of 

production equipment, making it difficult to realize.

Titanium and titanium alloys have been widely used as structural materials in aerospace, 

automobiles, diving, and medical implants due to their high specific strength, low modulus, 

excellent biocompatibility, and corrosion resistance. Porous titanium and titanium alloys 

make titanium and titanium alloys have the high surface area and low modulus functional 

properties by introducing pores, which extends the application of titanium and titanium 

alloys in orthopedic implant materials, battery electrode materials, sound-absorbing 

materials, and filter materials. The pore structure of porous titanium can be divided into 

two Types: 

closed pore structure and open pore structure. Porous titanium with a closed-cell 

the structure has high damping, sound-absorbing, and heat-insulating functions due to

its closed pores, and is mainly used in sound-absorbing materials and heat-protecting 

materials. Porous titanium with an open pore structure, because the pores are 

interpenetrated, has the functional properties of porous titanium with a closed pore 

structure, and also has filterability. It is mainly used in orthopedic implant materials, battery 

electrode materials, and filter materials.

At present, the preparation methods of porous titanium and titanium alloys are mainly 

traditional powder metallurgy technology, including powder loose sintering, adding more-

forming agent method, organic foam impregnation method, freeze casting, fiber sintering, 

and so on. Among them, i.h.oh et al.(script materials, 2003, 49, 1197) prepared porous 

titanium with a porosity of 37% through vacuum sintering of spherical titanium powder, 

and its Young modulus and bending strength are close to those of human bones. 

a.manonukul et al. (powder technology, 2014, 266, 129) selected polyurethane foam 

to soak in titanium powder slurry by the organic foam impregnation method and prepared 

porous titanium with a porosity of 84% by degreasing and vacuum sintering. The amount 

can reach 0.58gpa. The preparation technology of porous titanium is because there is a 

dense titanium dioxide oxide film on the surface of titanium powder, which hinders the 

electron migration between the titanium powders in contact with each other, so that they 

cannot be sintered by rapid heating by an electromagnetic field, and can only conduct heat 

to the powder through the above heating elements. The body is sintered under a vacuum 

conditions and the heating rate is slow, and the heating time is long, resulting in large 

dimensional shrinkage of the sintered body and the product size is difficult to control, 

which is not suitable for the preparation of porous titanium and titanium alloys with high 

porosity.
