THE ANALYTIC HIERARCHY PROCESS OF INFLUENCING FACTORS IN CARBON DIOXIDE CORROSION

The relative importance (i.e,weight) of the factors affecting CO2 corrosion of steels is a key for corrosion prediction and protection.However,the open literature generally can not explicitly define the relative importance of every influencing factor in definite quantity,which will affect the correctness of corrosion prediction and protection.Using analytic hierarchy process(AHP),the weights of various influencing factors were calculated,which quantitatively showed the relative importance of different factors.
