Product Features

DLC coating, or Diamond-Like Carbon Coating, is a surface coating technology that forms a high molecular carbon film on the surface of metal. Below is a detailed analysis of DLC coatings: I. Characteristics of DLC Coatings - High Hardness and Wear Resistance: DLC coatings possess a high level of hardness, with hardness values up to 70-110 GPa, comparable to that of diamonds. This makes them excel in wear resistance, effectively resisting scratches and abrasions. - Low Friction Coefficient: The friction coefficient of DLC coatings is typically below 0.2, and can even reach 0.005, significantly lower than that of traditional hard coatings (such as TiN, TiC, TiAlN, etc., with friction coefficients above 0.4). This gives DLC coatings a significant advantage in lubrication and friction reduction. - Chemical Stability and Corrosion Resistance: DLC coatings have excellent chemical stability and corrosion resistance, capable of withstanding erosion from acids, alkalis, and even other corrosive substances. - Good Optical and Electrical Properties: DLC coatings also offer certain optical and electrical properties, such as high transparency and high resistivity, making them suitable for surface coatings on optical components and electronic devices.
