22、method for checking the continuity of thin anodic oxidation coatings on aluminium and its alloys by a copper sulfate contact test. The use of this method is limited to anodic oxidation coatings of thickness less than 5 m, or coatings that have been deformed. NOTE The method described enables a rapid

23、 check to be made for the continuity of a thin coating of aluminium oxidation on aluminium and its alloys. In cases of doubt regarding a visible fault on the surface of a coating, the use of this method makes it possible to verify whether the fault corresponds to a local gap in the coating which exp

24、oses bare metal. 2 Principle Drops of copper sulfate reagent are placed on surface areas of about 100 mm2, chosen at will on the test pieces, avoiding the anodizing contact areas. If the area includes points where the metal is either bare or poorly covered, chemical deposition of copper takes place

25、on the aluminium, accompanied by a release of gas. The drops of applied reagent can be examined immediately upon application, either with the naked eye or with a magnifying glass, for the release of gas from points where the metal is bare, which is almost instantaneous. After the test, black and/or

26、dark reddish spots can be seen where the coating is not continuous. 3 Reagents 3.1 Copper sulfate solution, prepared as follows: copper(II) sulfate pentahydrate, (CuSO45H2O): 20 g; hydrochloric acid (20= 1,18 g/ml): 20 ml; distilled water or deionized water: make up to 1 000 ml. 4 Procedure Carry ou

27、t the test at room temperature. Remove all grease from the test piece. Mark out a test area of approximately 100 mm2on a horizontal part of the test piece, using a wax crayon or a rapidly drying lacquer to delineate the test area, leaving the test area itself unmasked. Cover the test area with the r

28、eagent (3.1), using approximately four drops. Leave the reagent in contact with the surface for 5 min, noting any release of gas, then rinse the area with clean water. Examine the surface and count the number of black and/or dark reddish spots per 100 mm2. DIN EN ISO 2085:2010-12 EN ISO 2085:2010 (E

29、) 4 NOTE For a more quantitative measurement, the average diameter of the black and/or dark reddish spots can also be estimated. 5 Expression of results Record the number of black and/or dark reddish spots per 100 mm2for each area examined and, if appropriate, their average diameter. 6 Test report T
