lämpöpinnoite

Lämpöpinnoite, also known as thermal coating or thermal spray coating, is a surface treatment process used to apply a layer of material to a substrate for various functional purposes. The core principle involves heating a coating material, typically in powder or wire form, to a molten or semi-molten state and then propelling it onto the surface of the object to be coated. Upon impact, the molten particles flatten, cool rapidly, and interlock to form a cohesive coating.

There are several thermal spray processes, including plasma spraying, flame spraying, high-velocity oxygen fuel (HVOF) spraying, and arc spraying, each offering different characteristics in terms of temperature, velocity, and particle form, allowing for the application of a wide range of materials. These materials can include metals, alloys, ceramics, and even polymers.

The primary applications of lämpöpinnoite are to enhance the properties of the substrate. This can include improving wear resistance, corrosion resistance, thermal insulation, electrical conductivity, or providing a decorative finish. For instance, in aerospace and automotive industries, thermal coatings are used to protect engine components from extreme temperatures and wear. In the medical field, they can be used for biocompatible implants. The versatility in material selection and application methods makes lämpöpinnoite a valuable technique for modifying surface characteristics across numerous industrial sectors.
