Special coating

Coating is an essential process to stabilize process conditions and extend lifetime through special coating treatment on the surface of equipment parts.
By providing a wide range of various coating technologies optimized for each customer's process, particles and surface damage can be controlled and by stabilizing the conditions of the chamber, the life time of the product, the production yield and the operation rate can be improved, also contributing to the cost reduction of the customer.

Types of coating technology

  • Anodized
    coating
    Anodized coating

    Technology for forming a solid aluminum oxide film (Al2O3) on the surface of aluminum through electrochemical reaction between aluminum (Al) and oxygen (O)

  • Thermal Spray
    Coating
    Thermal Spray Coating

    Technology of melting a coating material through heat and spraying it on the surface of parts to form a coating film

    Atmospheric Plasma Spray Coating (APS)

    The material to coat is instantaneously melted and sprayed using a high-temperature plasma under atmospheric conditions to form a coating film on the surface of products

    Generally suitable for ceramic powder coating

    Arc spray coating (Arc)

    Technology to instantly melt and spray the coating materials with low melting point by using electric discharge in order to form the film on the surface of products

    Suitable for metal coatings with low melting point

  • Aerosol
    deposition
    Aerosol deposition

    Technology of forming a high-density coating film without pores by colliding fine powders of ㎚ to ㎛ size to the surface of products under vacuum at very high speed without any melting process

  • Physical
    Vapor Deposition
    Physical Vapor Deposition

    PVD Coating is a technology that vaporizes materials such as coatings into a physical method (evaporation, sputtering) during a vacuum to form a dense coating on the surface of the product.

Main coating technology

Coating technology can be classified according to how to coat and its physical properties. In order to cope with a next-generation technology handing less than 10 nm, KoMiCo is developing various and unique coating technology.
