The results of the correlation analysis of the relationship between indicators characterizing the surface layer properties and signals reflecting the process of low-temperature plasma treatment of metal products

The paper presents the results of the correlation analysis of the relationship between the parameters characterizing the properties of the metal product surface layer with the parameters of signals reflecting the process of their low-temperature plasma treatment. It has been established that current signal parameters reflect the process of changing chemical and electrical (surface) properties, while the temperature signal parameters reflect the surface layer physical and mechanical (volumetric) properties.
