Abstract

Abstract:

Worldwide research on mechanical calendar life is carried out to obtain the calendar life of the metal under the premise of existing corrosion damage tolerance D_c. To make the application more available, this paper does not assume the existing corrosion damage tolerance D_c, and instead takes D_c as a variable and attempts to attain the calendar life of metal arbitrary corrosion damage D_i. It is found that the product of the concentration of corrosion experiment d_t and the experiment time H_t,divided by corrosion damage D_t, which is obtained from experiment, is equal to a constant. Therefore, a simple and highly feasible calculation model for metal arbitrary corrosion damage and the corresponding solution curve can be obtained. Through this model or curve, the calendar life of metal arbitrary corrosion damage can be obtained.

Key words: metal corrosion, corrosion damage tolerance, corrosion experiment, calendar life, calculation model
