The primary regulatory document is , which defines the general technical requirements for all metallic and non-metallic inorganic coatings. Key GOST Standards for Chrome Plating
: Standard designations and symbols for coatings (e.g., "Х" for chrome). gost hromirovanie
In technical drawings, chrome coatings are typically labeled according to . For example: Х9 : A 9-micrometer layer of chrome. The primary regulatory document is , which defines
: Applied in thicker layers directly to the base metal to improve wear resistance and hardness. Often used for hydraulic cylinders, shafts, and press molds. For example: Х9 : A 9-micrometer layer of chrome
: A softer, less brittle coating with micro-cracks that retain oil, making it ideal for engine parts and friction surfaces. Coating Designations
: Measurement of micro-hardness, often used to verify the durability of hard chrome layers. Main Types of Chrome Plating
The State Standard (GOST) regulations for chrome plating (hromirovanie) in Russia and the CIS cover various technical requirements, ranging from the general properties of the coatings to specific testing methods.
