Method, the main affecting laws that galvanic corrosion between different materials is investigated by both approaches.
In the influence factor of galvanic corrosion, galvanic couple to the distance between have important shadow to the corrosion behavior of galvanic couple pair
Ring.According to corrosion electrochemistry principle, increase the diffusion length that galvanic couple is just increased charged ion to spacing, it is molten equivalent to increasing
Liquid resistance, makes the mass transport process in electrolyte hindered.Under conditions of given anode and cathode area ratio and resistivity of media, electricity
Couple spacing is bigger, then Galvanic Current density is less.Anode and cathode process also has larger difference in corresponding galvanic corrosion.Cause
This, the effect of distance that galvanic couple pair is investigated in galvanic corrosion measurement is an important research contents.
In current galvanizing corrosion test, the spacing of electrode mainly by adjusting Winning cell in couple pole plate distance come
Realize, due to lacking fixed device, can only pass through to estimate probably fix the position of two pole plates, and in an experiment, for
The test of different size distance may need to change different size of electrolysis bath.These processes make troubles to test, also to survey
Amount brings certain error.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of spacing adjustable galvanic corrosion measurement electrolysis bath dress
Put, realize the galvanic corrosion measurement of different spacing.
For achieving the above object this utility model employs the following technical solutions realization：A kind of adjustable galvanic corrosion of spacing is surveyed
Amount electrolytic cell assembly, including a cylindrical shape electrolysis bath, it is characterised in that：The cylindrical shape electrolysis bath includes an inner sleeve and is arranged
Outer sleeve on the inner sleeve, the both sides of the cylindrical shape electrolysis bath are correspondingly arranged on respectively the plane of a center band circular hole
Plate, each surface plate has been orderly arranged outside each battery lead plate to be measured and a corrosion resistant plate, the surface plate, battery lead plate to be measured and not
Rust steel plate Jing bolts are fixed, and the both sides of cylindrical shape electrolysis bath are respectively arranged with a wiring and bolt connection.
Further, all portions of the circular hole are provided with cannelure, the cannelure on the lateral surface of the surface plate
Inside it is provided with matched annular rubber ring.
Further, it is provided with a filling opening on the outer sleeve.
Further, the outer wall of the outer sleeve is provided with graduation mark.
Further, the outer wall of the inner sleeve is frosting.
