A method for manufacturing an amorphous metal strip corrosion electrode

Abstract

The invention discloses a manufacturing method of an amorphous metal thin strip corrosion electrode, relates to the technical field of electrode corrosion, and solves the problems of poor stability of electric signal transmission, easy damage of the thin strip body and easy external interference of electric signals in the existing electrode corrosion. The key points of the technical solution are: select the copper clad laminate; remove the oxide layer on the copper clad surface; weld the contact between the wire and the copper clad surface firmly; remove the oxide layer on the thin strip body, Place some copper sheets between the copper surfaces and wrap them with water-sealing tape; use a glue gun to three-dimensionally seal the copper-clad laminate and the thin strip body, and reserve the parts to be corroded; use anti-corrosion materials to repeatedly smear and dry the parts that do not need to be corroded Dry, with the effect of ensuring the effective transmission of electrical signals during electrode corrosion, the integrity of the thin strip, and preventing the thin strip from shaking in the corrosive liquid, reducing the effect of external interference on electrical signals. This patent has been supported by the Science and Technology Fund of Guizhou Province (Qian Ke He J Zi [2014] No. 2122).

Description

technical field [0001] The invention relates to the technical field of electrode corrosion, more specifically, it relates to a manufacturing method of an amorphous metal strip corrosion electrode. Background technique [0002] As a new metastable material, amorphous alloy (also known as metallic glass) has high strength, low elastic modulus, and excellent corrosion resistance compared with crystalline alloys of the same composition. Amorphous alloys are widely used in high-tech fields such as engineering, precision machinery, information, aerospace devices, and national defense industries, and become key materials for improving performance and developing military functionality.

AI Technical Summary

Problems solved by technology

[0003] At present, for the alloy system with weak amorphous forming ability, the existing experimental equipment cannot make large amorphous alloys, and the amorphous alloys prepared by the melt quenching method (single-roller stripping method or double-roller stripping method) The thickness of crystal alloy thin strips is only micron level. To test its corrosion behavior or study its corrosion mechanism by means of potentiodynamic polarization, the thin strips must be made into corrosion electrodes for accurate testing.

[0004] However, since the thickness of the amorphous thin strip is only micron level, the width is generally 3-5 mm; the thin strips of different alloy systems have different mechanical properties, and some thin strips are not only thin, but also very brittle, and do not infiltrate with solder , it is impossible to weld wires on the thin strip body; for the thin strip body soaked with solder, it may also cause the thin strip body to crystallize during the welding process, causing damage to the material; during the corrosion test, any tiny Vibration will cause a large jump in the signal
