The test method defined in the ASTM B380 standard developed by the American Society for Testing and Materials (ASTM) is used to evaluate the corrosion performance of electro-precipitated copper/nickel/chromium and nickel/chromium coatings on steel, zinc alloys, aluminum alloys, plastics, and other substrates. abrasive) test method.
The test method presented in this standard, whose full name is "ASTM B380-97 Standard test method for corrosion testing of decorative electroplating coatings with the corrodkote procedure", is applied to the test samples with a slurry containing corrosive salts, allowing the slurry to dry and the samples coated with the slurry to high relative humidity for a certain period of time. performed by exposure.
Nickel/chromium and copper/nickel/chromium electro-deposition coatings are widely used for decorative and protective applications. Corrodkote testing provides a method for checking the quality of electroplated products and is suitable for production control and research and development.
The Corrodkote (abrasive) test is an accelerated test used to determine the coating corrosion resistance of electrode deposits. It is carried out by testing a dried sample alongside Corrodkote mud in a humid chamber. This test is primarily done to test the corrosion resistance of materials such as anodized aluminum. This test provides a faster indication of corrosion resistance and an improved correlation with performance.
Generally, this test is used to evaluate the corrosion performance of electro-deposited chromium/nickel and chromium/nickel/copper coatings on: steel, aluminum alloys, zinc alloys, plastics, and other surfaces.
Such tests have become essential for inspection and quality control. In many cases, there is no direct correlation between the results of the accelerated corrosion test and resistance to corrosion in other environments, because various factors that influence the progression of corrosion, such as the formation of protective films, vary widely with the conditions encountered.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides standard testing services for the corrosion test of decorative electroplating coatings with the corrodkote procedure, within the scope of ASTM B380-97 standard, with its trained and expert staff and advanced technological equipment. .
