Surcotec’s coatings and overlays offer a cost-effective solution for extending, upgrading or restoring the service life of components. Virtually any material that can be produced in wire or powder form can be processed into a coating or overlay. This means that there are thousands of possible coating and overlay options available to customers.
It is important to note that a monolithic material and its equivalent coating or overlay do not necessarily have the same properties and most materials are actually altered during the coating or cladding process.
The same material can also be applied as a coating or overlay using different processes which result in a coating or overlay with very different properties. Therefore great care is taken in the selection of the material and process to ensure that the desired functional properties are achieved.
Composite materials with unique functional properties can also be produced by combining different materials and processes.
Coating and overlay materials are generally classified as:
- Pure metals (e.g. molybdenum, copper)
- Metal alloys (e.g. Stellite®, Monel®, Inconel®, stainless steel (FeCr), NiCrBSi)
- Ceramics (e.g. alumina, zirconia, chrome oxide, hydroxyapatite
- Ceramic metal composite or carbide coatings (e.g. tungsten carbide, chrome carbide)
