METHOD FOR MEASURING THE ADHESION OF ICE TO SURFACES MADE OF DIFFERENT MATERIALS AND RESEARCH MODULE FOR IMPLEMENTATION THEREOF Russian patent published in 2022 - IPC G01N19/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to research equipment. Substance: the surface of a cone is coated, the cone is immersed in water or a saline solution in a conical container, followed by freezing in a thermostat, installing in the clamps of a universal testing machine, and determining the pull-off force of the coated cone from ice. The cone is made of an aluminium alloy, wherein prior to coating the surface of the cone, the pre-cleaned surface of the cone made of aluminium alloy is subjected to electrolytic oxidation in an electrolyte containing, g/l: 15 to 25 Na₂SiO₃·5H₂O and 1 to 2 NaOH, in the mode of plasma micro-discharges in the monopolar galvanostatic mode at a current density of 0.3 to 1.0 A/cm² and a polarising signal filling factor of 50%. The research module comprises a cone configured to be coated and a conical container. The cone is made of an aluminium alloy, wherein the pre-cleaned surface of the cone made of aluminium alloy is subjected to electrolytic oxidation in an electrolyte containing, g/l: 15 to 25 Na₂SiO₃·5H₂O and 1 to 2 NaOH, in the mode of plasma micro-discharges in the monopolar galvanostatic mode at a current density of 0.3 to 1.0 A/cm² and a polarising signal filling factor of 50%.

EFFECT: possibility of reducing the amount of tests needed for statistical validity of the results of estimation of the adhesion of ice to paint and varnish and powder coatings.
