It is insoluble in water and soluble in mixtures of nitric acid or hydrofluoric acid. It has a high melting point and is resistant to corrosion by air.
Wear Resistant
Titanium carbide is a hard refractory ceramic material that registers 9-9.5 on the Mohs scale. It is used in manufacturing wear-resistant materials and cutting tools. It also offers superior conductivity, high rates of purity, and excellent corrosion resistance.
It is a preferred material for wear-resistant coatings on machining tools. Its unique crystalline structure enables it to retain its dimensional stability at elevated temperatures and under extreme environmental conditions.
Wear-resistant metals are used in a wide variety of applications where the contact between two load-bearing surfaces needs to be minimized for safety and to ensure long service life of parts and components. These include the oil and gas, machining and mining industries.
These materials can be formulated with different abrasive particles to optimize wear resistance. They are also known to be durable and long-lasting, reducing the frequency of replacement or repair.
In addition to the use of abrasive particles, titanium carbide can be plated or welded onto metal components with a variety of welding processes such as laser-cladding. This process produces a thin, smooth and highly-resistant layer of carbide on the surface of metal.
The abrasive properties of titanium carbide can be influenced by the type of metal matrix and the ratio of reinforcement-matrix in a composite, i.e., the percentage of Titanium carbide (TiC) coating material particles deposited in a steel matrix. For example, a high content of TiC in a sintered alloy improves its abrasive wear resistance.
A high vanadium content is also associated with a significant improvement in abrasive wear resistance, which has been demonstrated in the case of HCCI-V [57]. In order to evaluate the performance of the new alloy, its abrasive resistance was tested in comparison with a standard high chromium cast iron (HCCI) under various test conditions.
The results showed that the surface layer exhibited an abrasive wear resistance comparable to abrasion-resistant steel AR400 in the metal-mineral abrasive wear test, which is very similar to that of titanium carbide. This property is likely attributed to the presence of the secondary carbide M23C6 in (1-11) and (220) crystal planes, which are distributed evenly throughout the surface layer.
Corrosion Resistant
Corrosion is the deterioration of a material through oxidation and chemical reaction with the environment. It affects not only the durability and strength of a material but also its cost. Besides metals, it can include non-metallic materials such as polymers and ceramics.
The corrosion resistance of a material can be expressed in units such as millimeters per year or "mils." These numbers indicate the rate of corrosion in terms of penetration depth and changes in mechanical properties. It depends on the environmental conditions that a material will be exposed to such as temperature, pressure and fluid velocity.
Stainless steels, which are iron-based alloys with a minimum of 10.5% chromium, have excellent corrosion resistance. However, if they are not heat-treated, they can become rusty under certain conditions, especially in a room-temperature environment.
Titanium is a silver-grey metal that can be alloyed to increase its strength and corrosion resistance. It is a good choice for structural and aerospace applications, where weight must be minimized but strength maximized.
It is also used for biomedical implants, where it stays inert inside the body while the body heals. This is a very important property, as it allows titanium to be used in the most difficult and delicate environments.
There are many forms of corrosion that can degrade titanium, such as general corrosion, crevice corrosion, anodic pitting, hydrogen damage and stress corrosion cracking. These corrosion methods are not entirely preventable and require special attention in any application involving the use of titanium alloys.
Corrosion-resistant coatings provide a protective barrier between the underlying metal and its surroundings that can delay corrosion. The coatings can be applied to both the surface and the interior of the underlying metal. They also act as a repelling layer that keeps dust and debris away from the underlying metal.
TiC-containing composite coatings have a high corrosion protection efficiency (PE %). It is due to the decrease of corrosion current density and increases in polarization resistance as the concentration of TiC particles increases. In addition, a higher corrosion protection efficiency can be achieved by increasing the concentration of TiC particles from 0.5 g L-1 up to 2.0 g L-1.
Electrical Conductivity
In the metals industry, electrical conductivity is a major concern. While Titanium carbide powder particles is a highly-resisting material for many applications, its low electrical conductivity makes it difficult to use in places where conductivity is important such as for power cables and other electric devices.
Fortunately, titanium carbide is much more electricallyconductive than titanium, making it an ideal choice for those looking to improve the conductivity of an existing structure. TiC is also highly resistant to chemical attack and will not burn in the presence of hydrochloric or sulphuric acid.
One of the main advantages of using titanium carbide is that it can be reacted with other materials to form new types of composites that have higher electrical conductivity than pure titanium. These composites have numerous uses in the electronics and telecommunications industries.
In order to improve the electrical conductivity of the composites, it is important to consider the conductive properties of the different fillers. For example, polyethylene (PE) is a widely used material for high voltage cables but it is susceptible to aging and damage during long-term operation. Various nano-fillers can be added to PE to improve its electrical conductivity.
PVA and PVP are two commonly used nano-fillers for PE. Both of them can suppress the space charge accumulation in PE, so they can effectively improve its electrical conductivity. Moreover, PVA and PVP also can increase the refractive index of the polymer.
The dc electrical conductivity of these polymer/TiC nanocomposites increases with the filler loading, which is beneficial for improving the electrical performance of the cables. However, the dc electrical conductivity of these PE/TiC nanocomposites decreases with temperature, which is different from that of pure PE.
Furthermore, the dc electrical conductivity of this TiC/PE composite increases with frequency, which is also helpful for the radiofrequency shielding of the cables. In addition, this composite can also suppress the oxidation of the copper in the cable.
Titanium carbide is often used as a protective coating for other metals and alloys. It is particularly effective at protecting nickel and copper from rusting, corrosion, or other harmful elements in the air. This is because it forms an oxide layer that renders the metal inert to the chemicals.
Thermal Conductivity
Titanium carbide is used in a variety of applications including aerospace, abrasives, cutting tools and as a material for hard alloys. It is an extremely hard and tough material that has a high melting point and is also a good conductor of heat.
The thermal conductivity of a material is defined as the rate at which it transfers heat between two points. This rate is determined by the time it takes for the temperature difference to travel from one area to another.
For titanium carbide, the thermal conductivity is 1.25 W/m2*K at 900 K and 3.15 W/m2*K at 1800 K. This is lower than that of tungsten carbide which has a thermal conductivity of around 80 W/m2*K.
In addition to its excellent thermal properties, titanium carbide has a number of other properties that make it a very desirable material for use in a variety of applications. In particular, it has high hardness, strength and fracture toughness and is resistant to corrosion.
Because it is very tough, Titanium carbide composite material has been used as a substrate for catalytic reactions that occur under extreme conditions such as radiation environments. However, it is important to note that when exposed to radiation damage, these materials may lose their initial performance significantly. This can be due to a reduction in the surface area of the titanium carbide or a decrease in the number of active sites on the surface.
Therefore, it is necessary to develop a material that can withstand radiation damage and improve its performance. This material must have an increased surface area or a greater number of active catalytic sites on the surface.
This is achieved by forming layers of TiC in a binder matrix. This matrix is then filled with an amorphous material such as aluminum or magnesium, which helps to reduce the density of the material and increase its mechanical strength.
The amorphous material is then cooled to room temperature and the layer of TiC is removed. The remaining titanium carbide is then ground and crushed to a fine powder. This powder is then incorporated into a steel alloy to form the desired metal.
