Abstract

Abstract:

The theory and model for the metal calendar life calculated by corrosion damage is discussed based on the research on the T-H curve and temperature and humidity spectrum of metal corrosion damage. This model proposed is able to calculate the metal's real calendar life when the corrosion T-H curve and the temperature and humidity spectrum in the real operational environment are provided. A comparison of the results of the calendar life calculation of 30CrMnSiA steel, with the experiment results in the real environment shows that the relative error of the steel is 17.5%. The comparison result shows that this model and method for calculating the metal calendar life is feasible.

Key words: corrosion damage, calendar life, temperature and humidity spectrum, T-H curve, calculation model
