Titanium Felts-Aegis

Detailed Specifications

How the Ti felts manufactured?

(1) Titanium Fiber Preparation: titanium raw materials are processed into micron-sized titanium fibers, which can be obtained through methods such as mechanical drawing, chemical vapor deposition, and electrospinning.

(2) Lay-up the Ti fibers: Titanium fibers are laid up in a certain way to form a fiber felt blank with a certain thickness and shape. The lay-up method will affect the pore structure and performance of the titanium felt.

(3)Sintering the ti fibers together: The fiber felt blank is sintered in a high-temperature vacuum environment. At high temperatures, the nodes between titanium fibers will fuse to form a solid three-dimensional network structure, which improves the strength and stability of the titanium felt.

Features

High Porosity: The porosity of Titanium felts usually ranges from 50% to 90%, with a large number of pores and channels. This allows gases and liquids to pass through quickly while providing a relatively large specific surface area.

Strong Corrosion Resistance: Titanium itself has excellent corrosion resistance. Titanium felt can remain stable in various corrosive environments such as acids and alkalis, is not easily corroded or damaged, and can work stably for a long time.

Large Surface Area: Ti felts with three-dimensional network porous structure gives it a much larger surface area than ordinary titanium products, which can provide more sites for chemical reactions, adsorption and other processes, and is conducive to improving reaction efficiency.

Good Electrical Conductivity: Titanium felt has good electrical conductivity, which can effectively conduct current in electrochemical devices and ensure the normal operation of the equipment.

Good Water Permeability: Porous Ti layers allows liquids such as water to pass through smoothly, and has advantages in some applications involving liquid filtration, separation, etc.

High Temperature Resistance: Titanium material can withstand relatively high temperatures, maintain the stability of its structure and performance in high-temperature environments, and can work normally in the temperature range from -200℃ to 480℃ or even higher.

Applications

Fuel cells: As a gas diffusion layer material, it plays roles such as electron conduction, gas diffusion, and water drainage in fuel cells, contributing to improving the performance and efficiency of fuel cells.

Water electrolysis for hydrogen production: It is an important flow field or diffusion layer material in electrolyzers, especially on the anode side. It can provide a good interface for the water electrolysis reaction and promote oxygen evolution and gas diffusion.
