The classification methods of thermal spray powder are diverse. According to the material, it can be divided into metal powder, alloy powder, ceramic powder and composite powder, etc.
Metal powders: such as aluminium powder, zinc powder, copper powder, etc., have good electrical conductivity, thermal conductivity and ductility, and are often used in anti-corrosion, conductive and other coatings.
Alloy powders: such as nickel-chromium alloy powder, iron-chromium-aluminum alloy powder, etc., integrate the advantages of multiple metals and possess excellent corrosion resistance, wear resistance and high-temperature resistance. They are widely used in aerospace, chemical and other fields.
Ceramic powders: such as zirconia powder, alumina powder, tungsten carbide powder, etc., have high hardness, high temperature resistance and wear resistance, and are commonly used materials for preparing wear-resistant and heat-insulating coatings.
Composite powder: Composed of two or more different materials, such as metal-ceramic composite powder, it combines the toughness of metal and the wear resistance of ceramic, offering more comprehensive performance and meeting the demands of complex working conditions.
The performance characteristics of thermal spray powder
The performance of thermal spray powder is the foundation for its effective application in various fields. Besides the application-related properties mentioned earlier, it also has the following characteristics:
Good stability: During storage and transportation, it is not prone to chemical changes and can maintain the stability of its own performance, ensuring the consistency of the spraying effect.
Controllable melting characteristics: Different types of thermal spray powders have different melting points and melting rates. They can be selected according to the specific requirements of the thermal spray process to ensure the quality of coating formation.
Excellent adhesion: It has a good bonding ability with the substrate surface, can form a firm coating that is not easy to fall off, and ensures the service life of the coating.
The future development of thermal spray powder
With the continuous advancement of technology, thermal spray powder is also constantly evolving. In the future, it will move towards a more refined, high-performance and functional direction.
Refinement: Through advanced preparation processes, powders with more uniform particle size and higher purity are produced, enhancing the quality and performance stability of the coating.
High performance: Develop powders with higher wear resistance, corrosion resistance, high-temperature resistance and other properties to adapt to more extreme working environments.
Functionalization: Develop thermal spray powders with special functions, such as those with self-healing and antibacterial properties, to expand their applications in more emerging fields.
As the core of thermal spraying technology, the continuous improvement of the performance of thermal spraying powder will drive thermal spraying technology to play an important role in more fields, providing strong support for industrial production and technological development.
