Gost — Hromirovanie

: Measurement of micro-hardness, often used to verify the durability of hard chrome layers. Main Types of Chrome Plating

: Methods for controlling and testing coatings, including checking for thickness, adhesion, and corrosion resistance.

: Applied in thicker layers directly to the base metal to improve wear resistance and hardness. Often used for hydraulic cylinders, shafts, and press molds. gost hromirovanie

: Standard designations and symbols for coatings (e.g., "Х" for chrome).

: Guidelines for choosing the type of coating based on the operating environment (light, medium, severe, or very severe conditions). : Measurement of micro-hardness, often used to verify

: General technical requirements (appearance, thickness, adhesion, and porosity).

: A softer, less brittle coating with micro-cracks that retain oil, making it ideal for engine parts and friction surfaces. Coating Designations Often used for hydraulic cylinders, shafts, and press molds

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.
