Technical field
The utility model relates to a kind of Experiment in Erosive Electrochemistry device, relates in particular to the electrolytic cell device of a kind of stereomicroscope and electro-chemical test coupling.
Background technology
Utilize stereomicroscope in-situ observation material surface erosion profile evolution process to have unique advantage, as not affected by corrosive medium, simple to operate, image is undistorted etc., particularly along with the raising of stereomicroscope enlargement factor, this technology must be more widely used.Can be used as strong replenishing to probe patterns in-situ corrosion research microscopes such as atomic force microscopes, be used for the relevance research between the Macrocosm and microcosm corrosion phenomenon, also can be used for the timely monitoring of long-term corrosion research.Yet, lack at present the electrolytic cell device of stereomicroscope in-situ corrosion morphology analysis special use in the laboratory.Some laboratories are reequiped voluntarily simple electrolytic cell or are replaced carrying out microexamination research with beaker, mainly have the following disadvantages:
1. easily pollute the mirror body: for the ease of observing, adopting open-top receptacle to carry out in-situ corrosion is the most conventional way, but the volatilization of corrosive medium, splash very large to the infringement of microscope ocular; Be difficult to carry out the corrosion research work that has uniform temperature to require.
2. can't realize with electro-chemical test synchronous: open-top receptacle can not be carried out electro-chemical test so that the galvanochemistry three-electrode system is difficult to fix, can not be fine corresponding with electrochemical signals thereby erosion profile is changed, greatly hinder the announcement of corrosion mechanism.
3. the liquid level smoothness is required high: stereomicroscope is that the liquid level of corrosive medium provides a light reflection surface undoubtedly by the visible light catoptric imaging, if liquid fluctuating or affected by bubble etc., judder and therefore distortion, is difficult to carry out CO
2, H
2Experimental study under the ventilation test experiments of the corrosive gass such as S and the corrosive medium agitation state.
Summary of the invention
Carry out in view of the above-mentioned stereomicroscope that utilizes that the electrolysis special pond exists many deficiencies or shortcoming in the in-situ corrosion research experiment, the utility model purpose is to provide the electrolytic cell device of a kind of single-minded kind of stereomicroscope and electro-chemical test coupling.
The purpose of this utility model can realize by following measures:
The electrolytic cell device of a kind of stereomicroscope and electro-chemical test coupling is characterized in that electrolytic cell is made as cylindrical or rectangle, comprises cylindrical shell, cover, the cylinder end, connects the bolt at cover and the cylinder end; Be provided with topping up cylinder, vent port, contrast electrode insert port by order from left to right on cover, view window is to electrode connection terminal, working electrode joint; The middle part is provided with the stirring magneton at the bottom of cylinder; The topping up cylinder vertically inserts the middle and lower part of cylindrical shell, and topping up cylinder upper end is provided with seal rubber plug, and seal rubber plug is provided with the draft tube of vertical insertion topping up cylinder bottom and is in the gas outlet of topping up cylinder upper end, and the draft tube lower end is provided with aeration head; Exhausr port on the cover is provided with plug, is inserted with contrast electrode in the contrast electrode insert port, and the cover in view window bottom surface ring week is provided with annular platinized platinum to electrode; The working electrode joint vertically inserts the top of cylindrical shell, is fixed with the specimen that level is put in working electrode joint lower end with bolt or snap ring.
On the surface of contact of cover and the cylinder end and cylindrical shell, be provided with separately annular groove, be provided with sealing gasket at the bottom of the groove.
The cylindrical shell of electrolytic cell, cover and the cylinder end, are made as the transparent body, make of plexiglas.
The electrolytic cell that the utility model provides, its advantage is:
1. avoid the mirror body pollution: owing to adopting closed structure, corrosive medium can directly or indirectly not contact with the mirror body, and view window and test piece close together can satisfy free operating distance and use greater than most stereomicroscope in-situ corrosion analyses of 50mm.
2. can realize corroding home position observation under ventilation or the stirring condition: the design of topping up mainly is that the factors such as liquid stirrings that ventilation is caused, bubble are limited in the liquid in pipe scope, simultaneously by the homogeneity of the interior UNICOM's realization liquid property of bottom and pond body.In the experiment, be full of corrosive medium in the body of pond fully, vent port is guaranteed residual air or learning gas are got rid of, and the stirring of liquid in the body of pond will can not cause the formation of new reflecting interface like this.
