Patent ID: 7704371

Claim:
A method comprising a computer programmed product embodied on a computer readable medium and configured to execute by microprocessor a method for predicting corrosion potential comprising instructions for executing the steps of providing an assembly comprising from 1 to i materials, and from 0 to j interfaces, wherein each interface is a contact between any two materials; calculating an RCI Material value for each material according to Formula I: RCI Material =RCI Base ×ƒ M ( F 1 M , . . . F n M ) [Formula I] wherein RCI Base is a real number or a function that may be evaluated to a real number that is unique for the material, ƒ M is a first scalar function, and F 1 M to F n M are material corrosion factors selected from the set of real numbers or functions that may be evaluated to real numbers; calculating an RCI Interface value for each interface according to Formula II: RCI Interface =RCI Material Max ×ƒ I ( F 1 I , . . . F m I ) [Formula II] wherein RCI Material Max is the largest RCI Material of the materials in the interface as calculated according to Formula I, ƒ 1 is a second scalar function, and F 1 I to F m I are interface corrosion factors selected from the set of real numbers or functions that may be evaluated to real numbers; and calculating an RCI Assembly value according to Formula III: RCI Assembly =ƒ A {( RCI Material ) 1 , . . . ( RCI Material ) i , . . . ( RCI Interface ) j } [Formula III] wherein ƒ A is a third scalar function, each RCI Material value is calculated according to Formula I, and each RCI Interface value is calculated according to Formula II; wherein the magnitude of RCI Assembly is based on the corrosion potential of said assembly.
