Product Features

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