Problems solved by technology

In order to obtain as sensitive and detectable current as possible by this method, it is necessary to ensure that the distance between the two metal sheets is as small as possible and insulated from each other; at the same time, multiple metal sheets are arranged in an interlaced manner, which is difficult to manufacture.

Embodiment 1

[0015] Use iron wire and copper wire with a diameter of 1mm, and the copper wire is an insulated enameled wire. Coat a thin layer of epoxy resin on a plexiglass cylinder with a diameter of 50 mm. Before the resin is cured, wind the iron wire and copper wire side by side around the cylinder for 50 turns, and then coat the surface of the metal wire with epoxy resin. After the epoxy resin is cured , the upper grinding machine grinds the outer diameter of the wound cylinder to 51mm. At this time, the two metal wires are exposed, and the insulation is good at the same time. The iron wire and the copper wire are respectively drawn out to form a Kovarni battery corrosion sensor.

[0016] After the sensor is completed, immerse it in 1% NaCl aqueous solution to measure its initial current value I 0 . Then expose (use) the sensor under natural conditions for a certain period of time, then polish the surface, and measure its current value I by immersing in 1% NaCl aqueous solution i , ...

Embodiment 2

[0020] Choose aluminum wire and copper wire with a diameter of 2mm, of which the copper wire is an insulating enameled wire, and coat a thin layer of epoxy resin on an engineering plastic cylinder with a diameter of 60mm. Before the resin is cured, wind the aluminum wire and copper wire side by side on the cylinder. 40 circles on the body, and then coat the surface of the wire with epoxy resin. After the epoxy resin is cured, the upper grinder grinds the diameter of the outer surface of the wound cylinder to 62mm. At this time, the two kinds of metal wires are exposed, and the insulation is good at the same time. The aluminum wire and the copper wire are respectively led out with wires to form a kohl Nickel battery corrosion sensor.

[0021] After the sensor is ready, immerse it in 1% NaCl aqueous solution to measure its initial current value I 0 . Then expose (use) the sensor under natural conditions for a certain period of time, then polish the surface, and measure its cur...

Abstract

The invention relates to a manufacturing method of an atmospheric corrosion monitoring sensor and belongs to the field of atmospheric corrosion monitoring of materials. Two different kinds of metal wires or threads enwind a surface-insulated cylinder side by side. The two kinds of metal wires or threads are insulated from each other. The outer surface of each kind of metal wires or threads is separately electrically contacted with the atmospheric environment. The two kinds of metal wires or threads are respectively led out with leads so as to form a Kovar cell sensor. Materials are easily available during the manufacturing process. By controlling thickness of vanished wire insulating layer, grinding depth and other factors, spacing distance between two metals is easy to control. The method has strong operationality. As there is no need to permeate insulation paste into a deep metal slit, metal of the sensor will not be damaged due to corrosion in the metal slit. Thus, reliability and endurance of the sensor are greatly enhanced.

Description

technical field [0001] The invention relates to a manufacturing method of an atmospheric corrosion monitoring sensor, which belongs to the field of atmospheric corrosion monitoring of materials. Background technique [0002] The corrosion of materials in the atmosphere is an important way of material damage. Observing and studying the atmospheric corrosion of materials is an important topic in materials research and application. Detection of atmospheric corrosion of materials by means of kovani cell type sensors is a common method. Its basic principle is to detect the corrosion of materials by detecting the microcurrent generated by two different metal materials in the thin liquid film state due to the difference in the potential of the materials. [0003] In order to obtain a measurable current, the general manufacturing method of the Kovarni battery sensor is to arrange multiple thin plates of two materials in an interlaced manner, and the middle of the thin plates is sep...
