Correlation analysis of the dependence of the established amount of tone (hue) in the reflected spectral (color) group and the corrosion resistance of alloys of the ni-cr-mo system: kh30n60m9, hastelloy g-35 with fcc – lattice

This article discusses the results of a correlation analysis between the indicators (parameters) of the established amount of tone in the spectral group of reflected visible light and corrosion resistance for single-phase nickel alloys of the Ni-Cr-Mo: Kh30N60M9, Hastelloy G-35 systems with a solid solution structure. The initial data for the analysis were the data obtained as a result of the analysis of the tone components of the reflected visible light by calculating the wavelength of the reflected light. The developed software estimated the amount of tone in the participating color groups, reflected visible light, where the tone is estimated by wavelength, determining the participating color groups. Further, the amount of tone determined in the color group is recalculated by the number of image elements - pixels, already offering the tone density in the color group. Corrosion rates were determined by a standard gravimetric method according to ASTM G-28 "A". Correspondence of the parameters: tone and corrosion rates for the alloys under consideration after various heat treatments indicated their high negative connection. The established fact allows us to state that a larger tone value determined for the pixel fragment characterizes a lower corrosion rate and better corrosion resistance in identical test conditions. The indicator correlation coefficient is determined at the level of - 0.93.
