1. Product Overview

Insulating cermet coatings are mainly used on the surface of parts with voltage or static electricity to provide excellent insulation performance and protect equipment from interference and damage caused by current, voltage and static electricity. This coating is usually composed of high-resistance inorganic crystalline materials (such as aluminum oxide, zirconium oxide, chromium oxide, etc.) and has excellent insulation, high temperature resistance, corrosion resistance and good mechanical strength.

2. Main Features

  • High insulation: The insulating cermet coating has an extremely high resistivity, usually in the range of 1010~1016Ω·m, which can effectively isolate current and voltage and prevent leakage and breakdown.

  • High temperature resistance: The coating can maintain stable performance in high temperature environments, with a temperature range of up to 1700°C or even higher, and is suitable for insulation protection under extreme high temperature conditions such as supersonic spacecraft.

  • Corrosion resistance: It has good chemical stability and can resist the erosion of corrosive substances such as acid, alkali, and salt, thus extending the service life of the equipment.
  • High mechanical strength: The coating has high hardness and wear resistance, can withstand certain mechanical shock and thermal shock, and protect the substrate from damage.
  • Convenient processing: Insulating cermet coatings can be prepared by a variety of processes, such as thermal spraying, sol-gel, electrochemical deposition, etc. The processes are flexible and diverse, and are convenient for large-scale production and application.

3. Application fields

Insulating cermet coatings are widely used in motors, electrical appliances, winding coils, induction equipment, insulating floors, transformer coils, windings and various insulating fiber materials. In the power industry, it can be used for insulation protection of high-voltage cables, transformers, generators and other equipment; in the electronics industry, it can be used for packaging and protection of integrated circuits, semiconductor devices, etc.; in the aerospace field, it can be used for thermal protection and insulation protection of rocket engines, satellites and other equipment.

4. Product Advantages

  • Improve equipment safety: By providing excellent insulation performance, it prevents leakage and breakdown, and ensures the safety of equipment and personnel.
  • Extend equipment life: It has good corrosion resistance and mechanical strength, can resist erosion and mechanical impact from the external environment, and extend the service life of the equipment.
  • Reduce maintenance costs: Due to the excellent performance of the coating, the number of equipment failures and repairs caused by insulation failure is reduced, reducing maintenance costs.
  • Environmental protection and energy saving: Some insulating cermet coatings are made of water-based inorganic materials, which meet environmental protection requirements and can reduce energy consumption during use.
