Wire beam electrode is a kind of for the dynamic (dynamical) electrochemical research method of Electrode interface microcell.The method is proposed by American at first at 20 century 70s, has been successfully used at present the research of the crevice corrosion, spot corrosion, microbiological corrosion etc. of metal.Wire beam electrode is to be parallel to each other and array (or being referred to as tow) that equally distributed tinsel (or being referred to as monofilament) forms by some.Each monofilament is insulated from each other, and its end face can represent a regional area of studied metal/electrolyte interface.The measuring circuit that each monofilament access consists of electrochemical workstation and wire etc. respectively, can measure the electrode process of electrode microcell, thereby studies the problems such as local corrosion of the unbalanced initiation of each microcell electrochemical properties.Typical wire beam electrode structure as Fig. 1 no.
Owing to using wire beam electrode technology to study, each monofilament need to be accessed respectively to measuring circuit, when tow is on a grand scale, when comprising 100 above monofilament, just face the electrical connection problem of the huge metal monofilament of quantity.Adopt traditionally welding lead one by one, or monofilament end is extended, form binding post.Front a kind of mode is very loaded down with trivial details, and due to spacing between monofilament very little (being generally less than 0.5mm), the easy short circuit of manual welding or rosin joint.Rear a kind of mode is difficult for realizing the scale of mass production of wire beam electrode test piece, and utilizes monofilament end to make binding post, and conducting wire end is difficult for sealing, can be by test solution corrosion.
Utility model content:
The purpose of this utility model is to provide a kind of wire beam electrode test piece and conductive seat for the test of microcell electrochemical behavior, and its conduction termination good sealing effect, can not corroded by experimental solutions, easy to use, easy and simple to handle.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises conductive seat 1, wire beam electrode test piece 2, wire beam electrode test piece 2 is fixed on conductive seat 1 by nylon screw, on described conductive seat 1, be provided with uniformly test piece register pin 3, the middle part of conductive seat 1 is provided with several spring needle 1-1, the lower end of spring needle 1-1 is connected with wire 1-4, the arranged outside of spring needle 1-1 has O shape circle 1-2, is provided with uniformly several threaded hole 1-3 on conductive seat 1.
In described wire beam electrode test piece 2, be evenly provided with several locating notch 2-2, locating notch 2-2 matches with test piece register pin 3, and the middle part of wire beam electrode test piece 2 is provided with tinsel 2-1.
In the utility model, the object of O shape circle 1-2 is to corrode elasticity contact pilotage in order to prevent infiltration test solution in the gap of test piece and base.The effect of test piece register pin 3 be and in test piece corresponding breach coordinate, guarantee that tinsel in test piece and the elasticity contact pilotage on base align.The effect of threaded hole 1-3 is to screw in hexagonal nylon screw, by screw cap, test piece is pressed on base securely, can oppress O shape circle simultaneously and deform, the gap on sealing surface of contact.
The utlity model has following beneficial effect: conduction termination good sealing effect, can not corroded by experimental solutions, easy to use, easy and simple to handle.
