Description
Technical field
The utility model relates to the improvement of Experiment in Erosive Electrochemistry equipment, specifically is the observation bogey of a kind of electrochemical corrosion experimental with electrode, and it belongs to the microbiological corrosion field in the metal corrosion and protection field.Microbiological corrosion is a crossing domain between microbiology and the corrosion science.Because of the scope of its generation is very extensive, and the economic loss of bringing is huge, so enjoy corrosion scientific worker's concern in recent years.
Background technology
Usually the metal material of required research being made exposed area in corrosion research is circular or square electrode, carries out electrochemistry experiment then in containing the electrolytic cell of certain medium.The making of kind electrode normally is circular with xsect or square cylindrical metal material is enclosed in the plastic tube with epoxy resin.One end of electrode is welded with a lead that has waterproof rubber, and solder joint is enclosed in the epoxy resin together with this face.The another side of electrode is exposure to place in the exsiccator after the mirror-like stand-by by sand papering, surface clean.Kind electrode can be applied to electrochemistry experiment repeatedly after polishing, but if electrode surface is carried out phenetic analysis, as fluorescence microscope, SEM (scanning electron microscope), ESEM (environmental scanning electron microscope), CLSM (scan laser Laser Scanning Confocal Microscope), AFM (atomic force microscope) etc. just can only will carry out behind the electrode destruction taking-up metal material.If the requirement of the off size phenetic analysis device of metal material may also will be cut it.This process is loaded down with trivial details time-consuming, also destroys the virgin state of material surface.Though these characterization techniques can be carried out original position, Real Time Observation to material, but before observing to material the processing stage longly had a strong impact on the researchist to the obtaining of some important information, restricted the application of these home position observation technology in microbiological corrosion research.So the present invention has designed utility model patent of invention " electrochemical corrosion experimental electrode ".This electrode assembly can carry out multiple electrochemistry experiment, and can take out the surface microorganism observation that electrode carries out multiple technologies, but still is some inconvenience when carrying out fluorescence microscope.This is all to have sample stage because of scanning electron microscope, environmental scanning electrode microscope, confocal laser scanning electron microscope etc., pellet electrode that will choose, that diameter is suitable is put into sample stage and can be observed before observing, this and to carry out the observation of fluorescent microscope different.Fluorescent microscope is to have increased devices such as excitation source, optical filter on the ordinary optical microscope basis, microorganism through dyeing can send fluorescence under excitation light irradiation, this to research electrode surface microbial numbers, anyway, diverse location is active helpful in distribution and the microbial film.Following some deficiency is arranged when using fluorescent microscope:
Will use oily mirror when 1), enlargement factor is greater than 800 times in microscopical use, normally 1000 times of enlargement factors when carrying out fluorescence microscope, at this moment not across a layer of air between observed electrode and objective lens but one deck cedar oil (step: after the dyeing of electrode surface attached microbial, drip cedar oil at electrode surface, cover a slice cover glass again, on cover glass, drip cedar oil at last again).Use oily sem observation can make observed object amplification multiple maximum, but oily lens head and observing object are very approaching, so when the adjusting objective table is selected the different visual field, pellet electrode is not easy to move simultaneously thereupon, this consequence that causes is exactly that selected different visuals field part repeats, can not reach the purpose of selecting the visual field at random, the error that this just causes the micro organism quantity statistics finally influences result of experiment;
2), in the process of traveling electrode, because under the slide cedar oil is arranged, the camera lens ionization electrode is very near, so may cause electrode and the slide can not same moved further, just the cover glass of electrode surface does not move thereupon when moving stage, this causes objective lens may touch sample surfaces on the one hand, may the pollutant lens head through the electrode surface of coloring agent dyeing, cause the inconvenience of experiment back clean lens; Moving when may drive the electrode surface microorganism of cover glass moved on the other hand, and this can cause the error of microorganism count, also can influence the observation that microorganism is distributed at electrode surface simultaneously.
3), because observing except using fluorescent microscope, microorganism also may use other technology, so used instrument and equipment difference selects for use the diameter of pellet electrode also different before the experiment.When selecting for use the less pellet electrode of diameter to carry out the fluorescence microscope process, cover glass is excessive by contrast like this, and electrode adds the whole center of gravity height of cover glass, so can cause electrode instability when observing.
4), because often will observe comparison to the electrode surface microorganism under the different condition, the mode that once can only observe an electrode obviously can easily not reach this purpose.
More than 4 deficiencies when being not only the common electrical chemical experiment and carrying out fluorescence microscope with electrode institute inaccessiable, even the pellet electrode after improving neither be very convenient when carrying out this operation.We have designed fluorescence microscope with sheet research electrode bogey for this reason.
Summary of the invention
The purpose of this utility model is to provide the observation bogey of a kind of electrochemical corrosion experimental with electrode.This device can be easily carries out fluorescence microscope to the microorganism of its electrode surface that carries.
The purpose of this utility model is realized by following technical scheme, has developed the observation bogey of a kind of electrochemical corrosion experimental with electrode, and it is installed on microscope stage or sample stage or the specimen holder.The plate face of itself and this objective table, seat form fit is provided with the groove cave of more than one carrying observation article, is mounted with the observation article in the bore in this groove cave, and the groove depth in this groove cave is slightly larger than or equals to observe the thickness of article.
Described observation article, it is the chip research electrode that is provided with cover glass, or the sheet research that is provided with cover glass is dull and stereotyped.
Described groove cave, itself or rise as high as the banks formula groove cave, the end, or formula groove cave at the bottom of the step trough; Also be filled with and observe the lining ring of contoured article coupling in this groove cave, this lining ring just in time serves as a contrast in the slit that is inserted between this groove cave internal diameter and the observation article external diameter.
Described lining ring, it is filled in the mode in this groove cave, also serves as a contrast in the slit that is inserted between this groove cave internal diameter and the observation article external diameter with 1-4 concentric lining ring.

Electrochemical corrosion experimental of the present utility model has following advantage with electrode observation bogey:
1). can be easily the microorganism of sheet research electrode surface be carried out fluorescence microscope.Sheet research electrode can not rock after putting into circular groove on the bogey, can move freely with bogey, the convenient visual field of selecting at random.
2). cover glass moves with electrode, and the phenomenon that relatively moves between cover glass and the electrode can not take place.
3). sheet that can different-diameter on same bogey is observed: both can once observe the electrode of same diameter, and can observe the electrode of different-diameter simultaneously again.
4) can carry out microscopic examination to the microorganism of a plurality of sheet research electrode surfaces relatively.
