METHOD FOR DETERMINING COATING THICKNESS Russian patent published in 2021 - IPC G01B5/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, namely to technologies for coating parts, and can be used to determine the thickness of coatings during their application by electron beam evaporation with condensation in vacuum. The method for determining the coating thickness includes measuring the values of the installation parameters for its application, while using a pre-formed database of measured values of coating thicknesses and the corresponding installation parameters when they are applied for a certain type of parts, according to which a mathematical model is created that reflects the relationship between the thickness of the applied coating and the installation parameters when it is applied: , where A, B, C, D, E are the coefficients of the regression equation obtained by statistical data processing; δ is the thickness of the applied coating, microns; In is the heating current, A; τ_h is the heating time, min; I_h is the heating current, A; τ_a is the application time, min; k, l, m, n are the calculated coefficients obtained by statistical data processing; before applying the coating, the thickness of the applied coating is calculated according to the obtained dependence, adjusting the parameters of the installation for its application to ensure the required thickness.

EFFECT: increased accuracy of determining the thickness of the coating during its application and an expansion of the technological capabilities of the coating method.
