DiamondLike Carbon (DLC) NanoCoatings for Enhanced Mechanical and Thermal Properties
Keywords:
DiamondLike Carbon (DLC), NanoCoatings, Mechanical Properties, Thermal Stability, Wear Resistance, Deposition Techniques, Tribological PerformanceAbstract
Diamondlike carbon (DLC) coatings are amorphous carbon films with a mixture of sp² and sp³ hybridized bonds that provide exceptional mechanical and thermal performance. These nanocoatings exhibit high hardness, low friction, excellent wear resistance, chemical inertness, and thermal stability, making them ideal for a wide range of industrial, biomedical, and engineering applications. This review examines the structure, deposition methods, mechanical and thermal properties, and performance of DLC coatings. It also discusses recent advances in composite and doped DLC films that improve adhesion, toughness, and resistance to high loads. The influence of deposition parameters on properties such as friction coefficient, hardness, and wear rate is analyzed. Applications in automotive, aerospace, tooling, and biomedical devices are highlighted, along with current challenges and future research directions.
