Pinnoitusmenetelmäryhmä

Pinnoitusmenetelmäryhmä refers to a classification of methods used to apply coatings or surface treatments to a substrate. These methods are grouped based on their underlying principles and the physical or chemical processes involved in transferring the coating material. Understanding these groups helps in selecting the most appropriate technique for a specific application, considering factors like material properties, desired coating characteristics, and cost-effectiveness.

Broadly, these methods can be categorized into several major groups. One significant category includes physical deposition techniques, such as vacuum deposition (PVD, CVD) and sputtering, where material is transferred in atomic or molecular form. Another group encompasses wet coating methods, like electroplating, electroless plating, painting, and dipping, where the coating is applied from a liquid medium. Thermal spray processes, including plasma spraying and flame spraying, form a distinct group where molten or semi-molten material is propelled onto the substrate. Mechanical application methods, such as rolling and brushing, also exist. Furthermore, chemical conversion coatings, which alter the substrate's surface chemistry to form a protective layer, represent another important classification. Each group within pinnoitusmenetelmäryhmä has its own set of advantages and limitations, influencing their suitability for different industrial sectors and product requirements.
