Estimating the term…
Surface coating method for applying a chemically bonded ceramic coating on a substrate, comprising the steps of preparing a powder mixture based on a hydraulic ceramic binder phase, preparing a substrate surface, applying at least one layer of the powder mixture on the substrate, and finally hydrating the powder layer/layers by addition of a water-based solution. The present invention method can be applied without using elevated temperatures, complicated and complex equipment, while maintaining control over the microstructure of the coating. The inventive procedure can suitably be used for producing general orthopaedic and dental implants. The inventive coatings can also be used in microstructure technology applications or in wear and friction applications.
Surface coating method comprising the steps:
Surface coating method according to claim 11, wherein the embedding is performed by blasting the surface with calcium aluminate fragments or powder.
Surface coating method according to claim 15, wherein the degree of compaction of the powder layer is increased between 30 and 80% and the porosity reduced to 30-45 vol.%.
Method of producing a surface coated biocompatible device, comprising the steps:
Biocompatible surface coating, wherein a binder phase in the coating substantially is comprised of calcium aluminate hydrate, or calcium silicate hydrate.
Surface coated device, comprising a substrate and a surface coating covering at least a section of the substrate surface, wherein the surface coating is a biocompatible surface coating comprising a binder phase substantially comprised of calcium aluminate hydrate, or calcium silicate hydrate.
