The ISO 9323 standard is well-known within the field of corrosion classes. Table 1 - Overview of the five corrosion classes according to the classification provided in ISO 12944 Part. One of the more important effects to take into account is that the corrosion mechanism might totally change when altering the corrosion conditions.

Nevertheless, it is important to perform accelerated tests that can simulate real, naturally occurring corrosion processes as accurately as possible. This is indeed a paradox, since an accelerated test will never be identical to long-term weathering. Thus, the more accelerated the test will be, the more severe the corrosion process will need to be, and the more unrealistic the test method will become.

However, the more accelerated the test method is, the less representative of the real world the test method will be, since it will involve test conditions far from actual environmental conditions. The more accelerated and the more reliable the applied test method is, the more favorable the accelerated corrosion test will be, since it is important to keep the required testing time as short as possible. Furthermore, such methods need to be so reliable that they can be integrated into the R&D process, providing not only a better, but also a more fundamental understanding of which coating parameters and formulations have a positive impact on the durability of the developed coatings. In order to accelerate coating development and provide reliable test methods capable of quantifying the performance of coatings with respect to their corrosion resistance, accelerated corrosion test methods need to be developed. In this paper, the results are discussed and compared.Ĭlassical method of evaluating atmospheric corrosion Different coatings of zinc and zinc/nickel, with and without different Cr +3 conversion coatings, were tested in salt spray, and the corrosion rate was recorded every five minutes. The ER monitoring makes it possible to study the corrosion rate online in remote locations as a function of temperature, relative humidity and changes in the composition of the atmosphere. This is expected to have a major impact on a number of industrial segments, such as test cars for the automotive industry, off-shore construction or components and devices used in harsh industrial environments. With this technique, very important information about the durability of a new conversion coating for aluminum, zinc and zinc alloys exposed to unknown atmospheric conditions can be gathered. The precise electrical resistance monitoring system can evaluate the corrosion to the level of nanometers, if the conductivity is compensated for temperature and magnetic fields.
