Titanium carbide, as a hard material with excellent physical and chemical properties, plays a vital role in cemented carbide. Carbide, as an indispensable high-performance material in modern industry, is widely used in extreme working conditions such as cutting, wear, high temperature and high pressure. Its performance directly affects product quality and production efficiency. The addition of titanium carbide not only significantly improves the hardness, wear resistance, oxidation resistance and fracture toughness of cemented carbide but also improves its processing performance and high-temperature stability, paving the way for the wide application of cemented carbide in many fields. Provides a solid foundation.

Improved hardness and wear resistance
Titanium carbide is known for its extremely high hardness, second only to diamond, a property that makes its use in cemented carbide particularly critical. When titanium carbide is added to cemented carbide, the hardness of the alloy can be significantly increased. The hardness value can reach 1800-2200HV, which is 20%-30% higher than pure cemented carbide material. This increase in hardness directly enhances the durability of carbide in cutting, wear and other applications. In addition, titanium carbide can also form uniformly distributed microscopic hardened materials in the cemented carbide. These hardened materials are like a "skeleton," supporting and strengthening the overall structure of the alloy, further improving its wear resistance.
Improvement of fracture toughness
Although cemented carbide has high hardness, excessive hardness often leads to a decrease in toughness, thereby increasing the risk of the material breaking during use. The addition of titanium carbide cleverly solves this problem. By forming finer, dispersed particles, titanium carbide plays a "bridge" role in cemented carbide, effectively alleviating the problem of reduced toughness caused by excessive hardness. At the same time, titanium carbide and other components in the cemented carbide (such as tungsten carbide) may form solid solutions during the sintering process. These solid solutions are distributed at the grain boundaries of the alloy and can hinder the expansion of cracks, thus improving the fracture toughness of the cemented carbide.
Improvement of processing performance
The production process of cemented carbide is complex and requires multiple high-temperature sintering and processing. The addition of titanium carbide significantly improves the processing properties of the material and reduces fracture or deformation during processing. This not only improves the production efficiency of cemented carbide but also reduces production costs and makes mass production possible. In addition, the addition of titanium carbide also makes the cemented carbide more stable during subsequent cutting, grinding and other processing processes, reducing tool wear and extending service life.
High-temperature stability and oxidation resistance
Titanium carbide has good oxidation resistance and can remain stable in high-temperature and high-pressure environments. This characteristic allows the cemented carbide added with titanium carbide to still have excellent durability in high-temperature and high-pressure environments. Whether in the fields of cutting, drilling, grinding or mold manufacturing, titanium carbide-coated carbide can demonstrate its excellent high-temperature stability. At the same time, the oxidation resistance of titanium carbide also ensures the long-term performance of cemented carbide in harsh environments and reduces the risk of performance degradation and failure due to oxidation.

Refine grains and improve overall performance.
Titanium carbide can inhibit the grain growth of other hard phases (such as tungsten carbide) during the sintering process, thereby refining the grains. Refining the grains helps improve the strength and toughness of cemented carbide, making it more stable and reliable when bearing high loads. In addition, titanium carbide can form solid solutions or compounds with other components to further improve the overall properties of cemented carbide. For example, the (Ti, W)C solid solution formed by titanium carbide and tungsten carbide can be distributed at the corners of WC, hindering the migration and growth of WC grains and thereby improving the hardness and wear resistance of the alloy.
Expansion of application fields
Due to the many excellent functions of titanium carbide in cemented carbide, this material has been widely used in many fields, such as machinery manufacturing, automobile manufacturing, aerospace, and mold manufacturing. In the field of machinery manufacturing, titanium carbide-coated cemented carbide tools have become the preferred tool for cutting due to their high hardness, high wear resistance and good cutting performance; in the field of automobile manufacturing, titanium carbide carbide materials are used to manufacture engines. Parts, braking systems and other key components; in the aerospace field, titanium carbide is used to manufacture key components such as turbine blades and bearings due to its high strength, high toughness and good high-temperature stability.
