Corrosion Based Design Approach (CBDA)

The CBDA is a specific approach to predicting performance. It is not an inherently mathematical method but rather a set of steps that require explicit consideration. However, many of the constituent steps require various levels of mathematical sophistication.

In discussing the dependencies of the steps in the CBDA as well as in the LAM, the term, "principal variables" is used. The principal variables as discussed here are those upon which the main phenomena of corrosion in aqueous systems depend. Similar variables apply to other environments. The seven principal variables that affect the modes of corrosion here are:

The ten steps of the CBDA are described here
