Abstract Scope Purpose of work was to control the quality of zinc coatings obtained on steels by the galvanic, thermal diffusion method under SHS conditions and hot. To control the quality of zinc coatings, a new developed standard ECP-Zn was used, which takes into account the operational properties, microstructure, phase composition, thickness of the zinc coating. A new zinc coating control scale has been developed, which has the following values: 0-0.15 - low quality, 0.16-0.35 - medium quality, 0.36-0.7 - high quality, 0.71-1.0 - high quality. Quality control of zinc coatings can be carried out quickly using a triopol, as well as with a complete assessment of the properties using a quatropol. New data were obtained on the structure and phase composition of zinc coatings consisting of phases: G-phase containing 25-27% by weight of iron. This intermetallic compound corresponds to the Fe3Zn10 compound with a microhardness of 5200 MPa.
