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

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.

Based on these standards, chrome plating is generally divided into three functional categories:

: 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.

: Provides a shiny, aesthetic finish while protecting against light corrosion. Usually applied over layers of copper and nickel.

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

In technical drawings, chrome coatings are typically labeled according to . For example: Х9 : A 9-micrometer layer of chrome.
