Abstract
A device which controls the depth of thin liquid film of electrolytic cell metal electrode surface is characterized in that: the device comprises a semi-seal box which is provided with a head cover with a hole, the semi-seal box is connected with a humidifier by a pipe, besides a probe which measures the depth of liquid film is arranged. The utility model has the advantages that: the relative humidity of measuring space can be adjusted on a large scale, the response speed is fast, the ability of keeping humidity is strong, and the controlling space of liquid layer can be reduced greatly, thus the requirement of controlling the depth of different liquid layer can be met.
Description
Technical field
The utility model relates to a kind of device of controlling surface of metal electrode thin liquid film thickness.
Background technology
The liquid layer thickness that need control during measuring on the metal surface when measuring the electrochemical behavior that approaches metal under the liquid layer is stablized constant.Conventional device is to place tank to keep certain relative humidity in measurement space, slow down the variation of evaporating the liquid layer thickness that causes, its major defect is that the tank velocity of evaporation is slow, measurement space is big, the steam speed that leaks is bigger, cause measuring liquid level district relative humidity and regulate slowly, the liquid layer thickness hold facility is bad, especially almost can't keep liquid layer thickness in Measuring Time when liquid layer as thin as a wafer.
Summary of the invention
The purpose of this utility model provides a kind of device of controlling surface of metal electrode thin liquid film thickness, it can be under measuring thin liquid layer to keep thin liquid layer thickness to stablize during the electrochemical metal behavior constant, make measurement result accurately reliable.
A kind of device of controlling surface of metal electrode thin liquid film thickness is characterized in that having a semitight box, and this semitight box has top cover, and is porose on the top cover, and this semitight box is communicated with humidifier by pipeline, is equipped with the probe of a mensuration thickness of liquid film in addition.
The utility model has the advantages that and can regulate the relative humidity of measuring the space on a large scale, response speed is fast, keeps the ability of humidity strong, can satisfy the requirement of various liquid layer thickness controls.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The device of the utility model control surface of metal electrode thin liquid film thickness has a semitight box 1, and this semitight box 1 has top cover 2, and is porose on the top cover 2, and this semitight box 1 is communicated with humidifier 3 by pipeline 5, is equipped with the probe of a mensuration thickness of liquid film in addition.
When using the utility model, the electrolytic cell of metal electrode to be measured is installed in the organic glass semitight box 1, make hole on the organic glass semitight box top cover 2 over against the middle part of electrolytic cell metal electrode, this hole also is used to put into the probe of measuring metal erosion behavior under the thin liquid layer.The metal electrode connecting line of electrolytic cell is picked out by the side of semitight box 1, inserts polarization device.Humidifier 3 is provided with adjusting knob 4, is used to regulate flux of moisture.In electrolytic cell, inject electrolytic solution with syringe, make electrolytic solution form the thin liquid film that needs thickness at surface of metal electrode.Open the power supply of humidifier 3, regulate the knob 4 of humidifier 3, the moisture of output desired flow.Thickness of liquid film with thickness of liquid film probe measurement surface of metal electrode.If thickness of liquid film diminishes gradually, the knob 4 of then regulating humidifier 3 flow that moisturizes is constant until thickness of liquid film.If thickness of liquid film increases gradually, the knob 4 of then regulating humidifier 3 reduces flux of moisture, and is constant until thickness of liquid film.Treating that thickness of liquid film is stablized starts polarization device when constant, carries out the polarization operation that needs and measures.
This device principal feature is to produce wet gas current with humidifier 3 to be full of semitight box 1, stablizes constant to keep thickness of liquid film.Can in very large range control relative humidity in the organic glass seal box 1 by adjusting knob 4, stablize constant requirement to satisfy long-time control thickness of liquid film.
The utility model parts relevant with circuit are known, and its circuit also is known, just have not been described further here.
