surfacecoated
Surfacecoated refers to a material whose surface has been modified by applying a layer of another substance, forming a coating. The coating is usually thin relative to the substrate and aims to provide properties not present in the base material, such as greater hardness, wear resistance, corrosion protection, lower friction, thermal stability, or biocompatibility.
Coatings are applied by deposition techniques including physical vapor deposition (PVD), chemical vapor deposition (CVD), electroplating,
Coating materials commonly used include nitrides and carbides for hardness, oxides for protection and insulation, polymers
Applications include cutting tools, automotive and aerospace components, medical implants, electronics packaging, and other parts where
Advantages include increased hardness, reduced wear and friction, improved corrosion and temperature resistance, and longer service
Characterization uses microscopy and spectroscopy to assess structure and composition, along with measurements of adhesion, roughness,
