Establishment of accelerated corrosion testing conditions

The development of the theoretical and experimental basis of accelerated atmospheric corrosion testing (ACT) of metals, whole machines and/or their components are discussed in this paper. It is apparent that current techniques for ACT should be improved. One approach, to establish the necessary environmental conditions for ACT on various products, is determine the range of metallic corrosion based upon the periodical wettings with KCl solution and drying process of a film of moisture, temperature and humidity in test chamber. An equation was created to describe one range of test chamber parameters for calculating the quantity of metallic corrosion as a function of these parameters. The experimental results were confirmed by checking the related statistics. The test demonstrated that the corrosive destruction of mobile machinery is dependent upon temperature, humidity, chemical and mechanical pollution, vibration and mechanical wear.
