| Abstract: | aterial damage function has been developed for calculating corrosion rate of specificmaterials and relevant service-life under different pollution levels on evaluation of economiclosses of material damage due to acid deposition. A series of experiments under differentconcentrations of SO2 and H+ have been conducted in the simulated environmental units spe-cially designed and constructed.Regression analysis has been performed with the resultingdata.The dualistic damage function of carbonate steel, galvanized steel,aluminum,marbleand paint have been developed by combining field exposure experiment results and the addi-tive contribution from corrosion. The errors are found to be 2%-38%. The separate con-tribution of acid deposition of corrosion rate is also given. |
