Simulation of the influence of test factors on the corrosion of metal materials tested for the aggressive influence of components of the industrial atmosphere in a salt spray chamber

Abstract

Simulation of the influence exercised by the main test factors (humidity, temperature, and aggressive components of the atmosphere) on the corrosion of metal materials was performed with the purpose to develop methods for corrosion testing of materials, junctions, and products in order to estimate the performance level of devices under all climatic operating conditions. Theoretical values of the acceleration coefficients were obtained for each test factor. Values of the test parameters were calculated, namely, concentrations of aggressive substances in a test chamber. Taking into account the earlier work on simulation of the influence of aggressive components in the industrial atmosphere on metal materials in a salt spray chamber, the concentrations of test solutions were calculated.
