Thermal Spraying

Thermal Spraying

Thermal spraying is a coating process whereby, in most cases, a powdery or a wire-shaped coating material with high thermal energy is spun onto a component surface where it creates a layer.
There are a number of different process variations, for example plasma spraying, high-speed flame spraying or arc spraying, which are used for processing a broad range of materials such as metals, ceramics and polymers into functional coatings. Layer thicknesses range from approx. 30 µm to several millimetres.

Thermal spraying is used in particular for wear-resistant combination layers, where an extreme surface hardness is to be combined with non-stick and sliding properties or enhanced traction properties.
