Description
Technical field
The invention belongs to the application field of metallic material corrosion field weightlessness method, and in particular to a kind of zero-g aircraft detection
The pickle of metallic material corrosion thing and application.
Background technology
Copper and its alloy are the metal materials closely related with mankind's activity.Because of its good conductive, heat conductivility, stabilization
Chemical property and the characteristic such as good ductility, plasticity, copper and its alloy are widely applied to electrical industry, electronics
The various fields such as industry, transportation industries, energy industry and marine industry.In the consumption of China's non-ferrous metal, the consumption of copper
Amount is only second to aluminium.In the application of metal material, inevitably etching problem.It is particularly more in corrosion factor
Under environment, the etching problem of copper and its alloy is especially serious.In the measurement of corrosion rate, conventional method is that corrosion increases weightlessness
Analysis.
During the weight loss rate of present analysis copper and its alloy, the method for selection is often according to national standard (GBT16545-
The removing of corrosion product on the corrosion sample of 2015 metals and alloy) carry out.The pickle that GB is recommended is washed including sulfamic acid
Liquid, hydrochloric acid lotion and sulfuric acid lotion etc..The pickle of recommendation is primarily present the problem of the following aspects when in use：It is first
First, part washing lotion is cumbersome using process, such as the hydrochloric acid lotion recommended in GB in the logical nitrogen of solution, it is necessary to dispel oxygen
Under conditions of carry out；Secondly, the pickling liquid acidity of recommendation is larger, the inevitably Metal Substrate during cleaning
The problems such as disproportionated reaction of serious and univalent copper ion is lost at bottom, so as to influence zero-g aircraft accuracy；Finally, GB is recommended
Different cleaning fluids weightless result has differences when in use, cause the comparativity when the result of different experiments is analyzed poor.Cause
This, prepares simple, the less pickle of acidity, in being applied to zero-g aircraft under the experiment flow of specification, in copper using one kind
And its seem most important in the weight loss rate test of alloy.
The content of the invention
Pickle and application it is an object of the invention to a kind of zero-g aircraft detection metallic material corrosion thing.
To achieve the above object, the present invention use technical scheme for：
A kind of zero-g aircraft detects the pickle of metallic material corrosion thing, and pickle presses volume mass (ml/g) than dense salt
Acid：Deionized water：Hexamethylenetetramine is 5:100:9-80；Wherein, control pickle pH is in 4.15-6.15.
It is preferred that, the pickle compares concentrated hydrochloric acid by volume mass (ml/g)：Deionized water：Hexamethylenetetramine is 1:10:
2-7, wherein, pickle pH is in 4.40-5.65 for control.
The concentration of the concentrated hydrochloric acid is 12M.
A kind of application of the pickle of zero-g aircraft detection metallic material corrosion thing, the pickle is in cleaning metal material
Carry out the application in zero-g aircraft detection metallic material corrosion thing.
Further：Metal material sample is placed in after being cleaned by ultra sonic bath in the pickle take out, then according to
It is secondary by running water, pure water, absolute ethanol washing, be subsequently dried and weigh；Then the cleaning fluid of above-mentioned cleaning said sample is entered
Row cycle pickling is complete to cleaning.
Further：When carrying out pickling, first, in the environment of ultra sonic bath, the sample that band becomes rusty is put into the acid for preparing
In washing lotion, timing 1 minute；Secondly, timing is rapid after terminating takes out sample, respectively through running water, deionized water and anhydrous
Ethanol is cleaned；Finally, sample is dried, is weighed using balance.Circulation above step, cleans 10 times, is carried out according to the data for obtaining
Zero-g aircraft.If after cleaning 10 times, the still visible corrosion product of specimen surface can suitably increase scavenging period.Above-mentioned cleaning fluid
In add hexamethylenetetramine regulation pH, and then improve the stability (H ion concentrations stabilization) when pickle is cleaned；Meanwhile,
Metallic substrates can be played corrosion inhibition by the loss of substrate when the pickle for adding hexamethylenetetramine reduces cleaning.In addition, making
Acid is hydrochloric acid, and the complexing power of chlorion serves the effect for suppressing monovalence copper disproportionation so that weightless result is more accurate
Really.
Advantage for present invention：
1. Acidwash solution of the present invention is prepared simple, it is not necessary to the operation such as logical nitrogen deoxygenation gas；Reagent, the medicine for using compared with
For common, and environment will not be impacted；
2. the regulation that the present invention passes through pH so that pickle does not have larger danger in use, while reducing monovalence
The disproportionated reaction of copper ion, it is ensured that Weight loss data is more accurate；In addition, the stabilization of pH also ensure that the stabilization of pickle of the present invention
Property so that the pickle can be used repeatedly.
3. pickle of the present invention is weak for the cleaning action of metallic substrates, while reducing substrate loss, it is ensured that lose
The accuracy of tuple evidence；
4. the experiment flow of the specification recommended by the present invention uses the pickle so that have between different experimental datas
There is comparativity.
