Materials used in hybrid coating technology

In hybrid coating technology, the materials used generally include the following types, each with different properties and applications:
Main material types
1. Ceramic materials:
• Alumina (Al₂O₃): Provides good wear resistance and corrosion resistance, often used to increase the hardness of the coating.
• Silicon nitride (Si₃N₄): Has excellent high temperature resistance and oxidation resistance, suitable for high temperature environments.

2. Metal materials:
• Titanium alloys(Ti): Commonly used in aerospace and medical equipment due to its light weight and high strength.
• Nickel-based alloys (such as Inconel): Have excellent corrosion resistance and high temperature strength, suitable for use in extreme environments.

3. Polymer materials:
• A mixture of epoxy resin and polyester resin: This combination provides good mechanical properties and chemical resistance, suitable for interior decorative coatings.
• Polyurethane: Has high wear resistance and elasticity, suitable for applications requiring flexibility.

4. Composite materials:
• Carbide composites: such as silicon carbide (SiC) or tungsten carbide (WC), provide extremely high hardness and wear resistance, suitable for cutting tools and molds.
• Multiphase composites: combine the advantages of different materials to achieve better overall performance.

5. Functional additives in coating technology:
• Antioxidants: such as aluminum titanium nitride (TiAlN), can improve the thermal stability of the coating.
• Lubricants: such as graphite or molybdenum disulfide, used to reduce friction and improve processing efficiency. Application examples
• In the aerospace field, hybrid coating technology is often used for engine parts to provide high temperature and corrosion protection.
• In the automotive industry, hybrid coatings of epoxy resin and polyester resin are used to improve the durability and appearance quality of the car body.
• In tool manufacturing, hard coatings such as tungsten carbide are used to improve the wear resistance of cutting tools.
These materials can not only improve the performance of substrates such as titanium alloys through hybrid coating technology, but also expand their scope of application in various industrial applications.
