: A softer, less brittle coating with micro-cracks that retain oil, making it ideal for engine parts and friction surfaces. Coating Designations
: Guidelines for choosing the type of coating based on the operating environment (light, medium, severe, or very severe conditions).
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. gost hromirovanie
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). : A softer, less brittle coating with micro-cracks
In technical drawings, chrome coatings are typically labeled according to . For example: Х9 : A 9-micrometer layer of chrome.
: Methods for controlling and testing coatings, including checking for thickness, adhesion, and corrosion resistance. The primary regulatory document is , which defines
: General technical requirements (appearance, thickness, adhesion, and porosity).
