Advances in The Preparation And Properties Of Titanium Nitride Carbide Composites

Titanium Carbide Nitride (TiCN) composites are materials with good comprehensive performance and have a wide range of applications. With the development of materials science and engineering, researchers have conducted in-depth studies on the preparation methods and properties of titanium carbide nitride composites. The purpose of this paper is to review the research progress on the preparation methods and properties of titanium nitride carbide composites.

Titanium nitrogen carbide composites are usually synthesized from three raw materials: carbon source, nitrogen source and titanium source. The commonly used preparation methods include solid-phase, vapor-phase and liquid-phase methods. The solid-phase method is to obtain the composites by mixing the carbon, nitrogen, and titanium sources and reacting them in a high-temperature environment. The gas phase method involves the introduction of nitrogen and carbon source gases into the titanium source in a gas phase reaction to produce titanium nitride carbonate composites. The liquid-phase method involves synthesizing the composites in a liquid-phase solution. Each of these preparation methods has its own advantages and disadvantages, and researchers can choose the appropriate method according to their research needs.

The properties of titanium carbide nitride composites mainly include mechanical, thermal, optical and electrical properties. Mechanical properties are important indicators for evaluating the strength and hardness of materials. Different mechanical properties of titanium nitride carbide composites can be obtained through suitable preparation methods and regulation of reaction conditions. Thermal properties are indicators for evaluating the high temperature resistance of materials, and titanium nitride carbide composites have high heat resistance and can be applied in high temperature environments. Optical properties refer to the material's absorption, transmission and reflection of electromagnetic radiation, titanium carbonitride composite materials have good optical properties and can be used in the preparation of optoelectronic devices. Electrical properties refers to the conductive properties of the material, titanium nitride carbide composite materials have high conductive properties, can be used in the preparation of electronic devices.
In addition to the above properties, the properties of titanium nitride carbide composites can be regulated by suitable preparation methods and the addition of appropriate amounts of other elements. For example, the hardness and electrical conductivity of the material can be regulated by controlling the carbon and nitrogen contents. The mechanical properties and wear resistance of the material can also be improved by adding transition metal elements. In addition, according to the application requirements, titanium nitride composites can also be modified, such as titanium nitride/silicon nitride composites, titanium nitride/aluminum nitride composites and so on.
