In order to use the four-probe method to determine the resistivity of a coating of high-entropy alloys, the correction functions were calculated when determining the resistivity based on measuring the potential difference between the probes placed on a hexagonal stainless steel sample coated with a conductive coating. The presence of boundaries with a non-conductive medium (air) and the presence of a conductive substrate with a conductive coating were taken into account. The method of mirror images was used for the calculation. Correction functions for a hexagonal sample with a thin coating are obtained.
