composietcoatings
Composite coatings are thin films formed by combining two or more materials to achieve properties greater than those of the individual constituents. They typically incorporate a continuous matrix phase (metal, ceramic, or polymer) with dispersed reinforcement such as particles, fibers, or whiskers. This combination is designed to improve hardness, wear resistance, thermal stability, corrosion resistance, or reduced friction.
Common categories in coatings include metal matrix composites (MMCs), where ceramic or hard particles are embedded
Deposition methods for composite coatings range from physical vapor deposition (PVD) and chemical vapor deposition (CVD)
Key properties include high hardness and wear resistance, elevated temperature capability, chemical inertness, and reduced friction.
Applications span cutting tools and molds, aerospace and turbine components, automotive parts, electronics, and biomedical implants.
