: A softer, less brittle coating with micro-cracks that retain oil, making it ideal for engine parts and friction surfaces. Coating Designations
: General technical requirements (appearance, thickness, adhesion, and porosity).
Based on these standards, chrome plating is generally divided into three functional categories: gost hromirovanie
: A multi-layer coating consisting of 15µm copper (M), 15µm nickel (N), and a final layer of bright chrome (X.b).
: Provides a shiny, aesthetic finish while protecting against light corrosion. Usually applied over layers of copper and nickel. : A softer, less brittle coating with micro-cracks
: Methods for controlling and testing coatings, including checking for thickness, adhesion, and corrosion resistance.
: Standard designations and symbols for coatings (e.g., "Х" for chrome). : Provides a shiny, aesthetic finish while protecting
: Applied in thicker layers directly to the base metal to improve wear resistance and hardness. Often used for hydraulic cylinders, shafts, and press molds.
