Titanium carbide coatings are used in various areas of application. They have a wide range of tribological properties and are particularly effective in wear-resistant coatings for machine parts, devices and tools.
Hardness
Titanium carbide has a wide range of hardness values and can be used for wear-resistant materials. Generally, the harder the material is, the greater its shock resistance and impact strength.
The toughness and resistance of plastic deformation is determined by the WC grain size. Grades with finer, more Co-rich binder and WC grain sizes will be more durable and less susceptible to wear.
The amount and composition of the Co-rich binder is also critical to the material's toughness and resistance to plastic deformation. A higher percentage of binder at the same WC grain size will result in a tougher grade. However, a lower percentage of binder may result in a more brittle part.
Various additives can be used to add strength and/or wear-resistance to Titanium carbide powder particles. Examples include: boron carbide, titanium carbonitride and nickel/chrome alloys.
Wear Resistance
TiC wear-resistant materials are often used in the production of metal cutting tools such as dies and punches. They are extremely resistant to wear and have a long life expectancy.
They can also be used as a coating for abrasion-resistant metals. The Titanium nitride carbide properties include high hardness, fire resistance, and corrosion resistance.

These characteristics make them a good choice for extreme environments where severe sliding wear is common. They are also abrasion-resistant, durable, and can be used for cutting titanium alloys.
Titanium carbide wear-resistant materials are mainly used in military, aerospace, mechanical processing, metallurgy, petroleum drilling, mining tools, electronic communications, and construction. The use of these materials is expected to increase with the development of downstream industries.
Thermal Conductivity
Titanium carbide (TiC), is a heat-resistant material. It has a high melting temperature, making it ideal for many different applications such as heat-resistant armor plating or cutting tools.
TiC is typically used in cermets, hard alloys, heat-resistant alloys, anti-wear materials, and high-temperature radiation devices. It is also a very good conductor of electricity.
TiC has a high thermal conductivity and is resistant to corrosion. It is often added to cemented tungsten-based carbides to enhance hardness and wear resistance.
Modern pelletizing operations use a majority of Ferro-TiC and WC-Co alloys as die faces. These alloys are based on metal matrix composites of titanium carbide, chromium, molybdenum, and/or a WC-Co binder. These alloys are less brittle and one half the weight of a similar steel-bonded tungsten carbide alloy.

Chemical Stability
The chemical stability of Titanium carbide composite material and wear-resistant materials is an important factor for reducing the risk of damage in metalcutting applications. Titanium carbide is a wear-resistant compound that is highly resistant and has high hardness.
The material has excellent chemical properties, including a high melting temperature (up to 3140 degrees Celsius), thermal expansion coefficient (7.74 x 10-6/K), heat formation (about 183 KJ/mole) and good lubricity. In addition, titanium carbide is resistant to a variety of oxidizing environments and has good durability, making it suitable for use in a wide range of high-temperature and demanding applications.
The chemical stability of the material is improved by enhancing the boron and carbon content through self-sustained reactions with titanium dioxide. This process can be used for ceramic composite bodies and materials that can withstand harsh conditions. Additionally, it may be used to make wear-resistant coatings for a variety of metal-cutting applications.
