As an important ceramic material, titanium diboride (TiB2) has extremely high hardness and thermal stability, as well as good wear resistance and corrosion resistance, making it an ideal choice for cermet. It is widely used in the manufacture of high-strength, wear-resistant tools, cutters, and abrasives. In addition, the excellent electrical conductivity and high thermal conductivity of TiB2 make it of great value in the field of electronic device applications, such as playing the role of heat conduction in electronic packaging materials, or being used as a conductive layer or lead wire for microelectronic devices.
TiB2 can also be used in the preparation of functionally graded hard alloys (FGHC). FGHC is a material whose composition, structure, and properties vary gradiently in space. By controlling the content and distribution of TiB2, a gradient structure can be formed in the hard alloy to meet different application requirements, such as hardness, toughness, and corrosion resistance. This structure enables the material to have optimized performance in different regions, thereby meeting specific application requirements. The applications of TiB2 in cermet and FGHC demonstrate its broad application prospects, which not only improve the properties of materials but also broaden their scope of use.
