Pinnoitusprosessin

Pinnoitusprosessi refers to the Finnish term for a coating process. It encompasses a variety of techniques used to apply a layer of material onto a substrate for a specific purpose. These purposes can include protection against corrosion, wear, or chemical attack, as well as aesthetic enhancement, electrical conductivity, or improved surface properties. The choice of coating material and the application method are crucial and depend on the desired outcome and the nature of the base material.

Common coating processes include electroplating, where a thin metal layer is deposited onto a conductive surface using an electrochemical bath. Another method is powder coating, which involves applying a dry powder electrostatically and then curing it with heat to form a solid, durable finish. Spray coating, whether wet or dry, is also widely used, employing various techniques like air spraying, airless spraying, or electrostatic spraying to apply liquid or powder coatings. Physical vapor deposition (PVD) and chemical vapor deposition (CVD) are advanced techniques often used for high-performance coatings, particularly in industries like electronics and aerospace. Thermal spraying, where molten or semi-molten material is propelled onto a surface, is another important category. The substrate preparation is a critical preliminary step in most pinnoitusprosessit to ensure good adhesion and the longevity of the coating.
