metallointiin

Metallointiin is a Finnish term that translates to "metallization" or "metal spraying" in English. It refers to a group of thermal spray coating processes where molten or semi-molten material is applied to a surface to create a protective or functional coating. The most common methods involve heating a metal wire or powder and then propelling it towards the substrate using compressed air or gas. The impact of these droplets flattens them out, forming a cohesive layer as they cool and solidify.

The primary purpose of metallointiin is to enhance the properties of the substrate material. This can include improving corrosion resistance, wear resistance, hardness, or providing electrical conductivity. It is particularly useful for repairing worn or damaged components, as well as for applying new functional surfaces to existing structures. Common applications are found in industries such as construction, shipbuilding, manufacturing, and energy production, where protection against harsh environments or wear is crucial.

The materials used for metallointiin vary widely depending on the desired coating properties. Metals like zinc, aluminum, steel alloys, and bronze are frequently employed. The surface preparation of the substrate is a critical step to ensure good adhesion of the applied coating. This often involves abrasive blasting to create a rough profile for the molten particles to grip onto. Metallointiin is a versatile technique that can be applied to a range of substrates, including steel, cast iron, and concrete.
