Abstract
The utility model discloses a couple pair hanging device for a couple corrosion test, which belongs to the technical field of material corrosion tests and is composed of a hanging rod, a sample fixing block and a connection screw. Screw holes are arranged on the hanging rod and the top face of the sample fixing block, and the screw holes are matched with the connection screw to connect the hanging rod and the sample fixing block. The couple pair hanging device for the couple corrosion test ensures that two components of the couple pair are always arranged abreast and vertically during the test, and the distance between the two components is 30mm, so that experimental errors caused by the fact that relative position of the couple pair is not stable during the test can be effectively removed.
Description
Technical field
The utility model belongs to the material corrosion technical field of measurement and test, and particularly a kind of galvanic couple of bimetallic corrosion test usefulness is to hanger.
Background technology
In industries such as oil, chemical industry, mine, bimetallic corrosion also is because the difference of its electrode potential comes in contact corrosion in the variety classes of in corrosive medium, connecting each other or the metal material material regular meeting of the different trades mark.The negative metal material of electrode potential is understood accelerated corrosion usually and was lost efficacy fast.For guaranteeing effective utilization of material; The designer is before selecting material; Be necessary the variety classes that possibly connect or the metal material of the different trades mark are carried out the bimetallic corrosion performance test, with the evaluation and test material corrosion rate under the connection situation each other in the corrosive medium in-service.Metal material bimetallic corrosion method of testing is generally carried out with reference to GBT 15748.Because the right spatial placement (geometrical factor) of galvanic couple is one of principal element that influences bimetallic corrosion speed.Therefore explicitly call in this standard method: specimen size is 100mm * 30mm * 2mm; Two constituent elements of every group of couple must vertically be placed side by side, guarantee that simultaneously spacing is 30mm.If there is not suitable hanger, rely on nature to place merely, be difficult to accomplish to keep spacing and the vertical side by side state of 30mm at the right constituent element of test period galvanic couple always.If can not accomplish this point, will certainly bring the experimental error that the instability of relative position is caused because of galvanic couple to test findings.
The utility model provides such hanger, guarantees at test period, and right two constituent elements of galvanic couple are vertically placed from start to finish side by side, and both keep spacing is 30mm, the experimental error that because of galvanic couple the instability of relative position is caused with effective eliminating test period.
The utility model content
The purpose of the utility model provides a kind of galvanic couple of bimetallic corrosion test usefulness to hanger.This hanger can guarantee two right constituent elements of galvanic couple during carrying out the bimetallic corrosion performance test from start to finish spacing 30mm vertically place the experimental error that because of galvanic couple the instability of relative position is caused with effective eliminating test period side by side.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of galvanic couple of bimetallic corrosion test usefulness is to hanger; It is characterized in that: this hanger is made up of hanger bar, sample fixed block and connecting screw rod; On the hanger bar with the sample fixed block on end face be provided with threaded hole, threaded hole matches with connecting screw rod hanger bar and sample fixed block is linked together.
Threaded hole on the hanger bar can be located at the centre of hanger bar.
Suspension peg, sample fixed block and connecting screw rod are processed by plastics, polytetrafluoroethylmaterial material or titanium alloy material, can use under the deep-etching condition or under the hot conditions with warranty test.
Hanger bar can be rectangular strip or semicircle strip.
It is the parallel surface of 30mm that the sample fixed block has two spacings.
The height of sample fixed block is at least 35mm.
During use, can galvanic couple be fixed on two parallel surfaces of sample fixed block with plastics electrical isolation adhesive plaster constituent element.
The beneficial effect of the utility model is: the galvanic couple of the bimetallic corrosion test usefulness that the utility model provides is guaranteed test period to hanger; Two right constituent elements of galvanic couple are vertically placed from start to finish side by side; Between the two apart from 30mm, the experimental error that because of galvanic couple the instability of relative position is caused with effective eliminating test period.
The galvanic couple of a kind of bimetallic corrosion test usefulness that the utility model provides is to hanger; To the metal material of the variety classes or the different trades mark during carrying out the bimetallic corrosion performance testing; Be difficult to effectively to guarantee that galvanic couple keeps the problem of the state that spacing 30mm vertically places side by side to the group member; The hanger of being made up of hanger bar, sample fixed block and connecting screw rod is provided,, has effectively got rid of the experimental error that test period causes the instability of relative position because of galvanic couple to address this problem.The hanger that the utility model provides is processed by plastics or polytetrafluoroethylmaterial material or titanium alloy material, can use under the deep-etching condition or under the hot conditions with warranty test.
Through accompanying drawing and embodiment the utility model is further specified below, but and do not mean that restriction the utility model protection domain.
