Abstract
Detection method is scratched the invention discloses a kind of plane aluminium alloy skin-surface, two kinds of display solution are prepared first and neutralize solution, after go part surface dirt, then isolate away from doubtful abraded area, the display solution 1 prepared dripped in doubtful abraded area, rinsing checks the color of doubtful abraded area, display solution 2 is dripped again, and rear clear water rinses doubtful abraded area, neutralized, rinsed and dried, according to doubtful abraded area whether it is black after drying, to determine whether covering scratches.The plane aluminium alloy skin-surface of the present invention scratches detection method, by corroding display detection, correctly authenticated aluminum alloy outer cover surface tear, controls product quality.
Description
Technical field
The invention belongs to the Physico-chemical tests field of aluminium alloy, and in particular to a kind of plane aluminium alloy skin-surface scratches detection
Method.
Background technology
Currently, the domestic scuffing for aircraft skin, is observed using the method for artificial visual all the time.This
Whether the manual detection mode of sample, the depth scratched for covering and stroke can not accurately differentiate aluminium coating thoroughly, for follow-up
Troubleshooting also without reliable foundation.In addition, domestic scratch Physico-chemical tests method there is presently no corresponding aircraft skin.
Abroad in technology, there is the Physico-chemical tests method for solving aluminum alloy outer cover surface tear.This method need by
Part is cut, and passes through chemical attack, chemical reaction, to determine the degree of component corrosion.And for the differentiation of scratch depth, due to
Part is very big, and cutting sampling inspection is unable to again, external also without a kind of effective method, can only be wrapped by chemical method
The detection whether aluminium lamination is drawn, so that it is determined that the degree scratched.
The content of the invention
Detection method is scratched there is provided a kind of plane aluminium alloy skin-surface instant invention overcomes the deficiencies in the prior art, is
Solution aluminum alloy outer cover scuffing degree test problems, by chemical corrosion method, aluminium coating is judged using chemical principle
Whether draw, it is determined that the degree scratched.Whether offer reference can be used for the follow-up covering.
To achieve the above object, the detection method of the not chemical attack of cutting parts is taken in the present invention, is specially：
A kind of plane aluminium alloy skin-surface scratches detection method, comprises the following steps：
1) prepare and show solution 1：Using 200g potassium nitrate+100g sodium hydroxides, 1L is diluted to deionized water；
2) prepare and show solution 2：Using 100 milliliters of HNO3+200 to 300 milliliters of H2O；
3) prepare and neutralize solution：Using 50g chromic acid, 1L is diluted to deionized water；
4) according to piece surface vestige, visual inspection determines doubtful abraded area；
5) dust, doubtful abraded area is cleaned with clean cloth；
6) skin-surface is cleaned with butanone, beyond being isolated before volatilization with adhesive tape away from doubtful abraded area center 3mm
Region；
7) the display solution 1 prepared is dripped in doubtful abraded area, is maintained 1-3 minutes；
8) clear water rinses doubtful abraded area, does not allow to wipe；
9) color of doubtful abraded area is visually inspected, if color blackening, primarily determines that covering is scratched；
10) drop 1-2 drops show solution 2, maintain 0.5-1 minutes, and clear water rinses doubtful abraded area, do not allow to wipe；
11) neutralize：Neutralization solution is dripped, is maintained 2-3 minutes；
12) clear water is rinsed, dried；
If 13) doubtful abraded area remains as black after drying, then carries out a step 10), if doubtful afterwards scratch
Position remains as black, then final to determine that covering is scratched；If not finding blackening, it is determined that covering is not scratched.
The plane aluminium alloy skin-surface of the present invention scratches detection method, by corroding display detection, correctly authenticated aluminium
Alloy skin-surface is scratched, and controls product quality.
Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
Detection method is scratched using the plane aluminium alloy skin-surface of the present invention and carries out 2024 aluminum alloy outer cover surface tears
Detection, is concretely comprised the following steps：
1) prepare and show solution 1：Using 200g potassium nitrate+100g sodium hydroxides, 1L is diluted to deionized water；
2) prepare and show solution 2：Using 100 milliliters of HNO3+200 to 300 milliliters of H2O；
3) prepare and neutralize solution：Using 50g chromic acid, 1L is diluted to deionized water；
4) according to piece surface vestige, visual inspection determines doubtful abraded area；
5) dust, doubtful abraded area is cleaned with clean cloth；
6) skin-surface is cleaned with butanone, beyond being isolated before volatilization with adhesive tape away from doubtful abraded area center 3mm
Region；
7) the display solution 1 prepared is dripped in doubtful abraded area, is maintained 1-3 minutes；
8) clear water is rinsed, and does not allow to wipe；
9) doubtful abraded area color is visually inspected, if color blackening, primarily determines that covering is scratched；
10) drop 1-2 drops show solution 2, maintain 0.5-1 minutes, clear water rinsing, do not allow to wipe；
11) neutralize：Neutralization solution is dripped, is maintained 2-3 minutes；
12) clear water is rinsed, dried；
If 13) remain as black after drying, then carry out a step 10), it is final to determine covering if remaining as black
Scratch；If not finding blackening, it is determined that covering is not scratched.
