Titanium foam consists primarily of titanium, a strong and lightweight metal. Its structure resembles that of a sponge, with a network of interconnected pores. This porous structure gives titanium foam its exceptional properties, like low density and high strength. The manufacturing process influences the characteristics of the foam, including its porosity and mechanical strength.
Titanium foam is primarily made from titanium powder. This powder is often alloyed with other metals to enhance specific properties. Common alloying elements include aluminum, vanadium, and iron. These elements improve the material's strength, corrosion resistance, and biocompatibility.
The production process involves creating a titanium powder mixture, which is then transformed into a foam through various methods. One common technique is the space-holder method. In this process, a space-holder material is combined with the titanium powder. After sintering, the space-holder is removed, leaving behind a porous structure.
The production of titanium foam typically follows several key steps:
Powder Preparation
The first step involves sourcing high-purity titanium powder. This powder is then blended with additives, such as space-holders.
Mixing and Shaping
The titanium powder mixture is shaped into desired forms. This can be done using methods like uniaxial pressing or injection molding.
Sintering
The shaped components are then subjected to high temperatures in a furnace. This process helps bond the powders, achieving a solid structure.
