Passivation, Pickling and Electropolishing Scope Comparator

Compare the review questions each scope can raise. This is a boundary guide, not a route selector or performance ranking.

Passivation

Question to resolve

Is reactive surface contamination or free iron the concern to review?
What material, governing requirement, processor scope and verification evidence must align?
Do not assume a chemistry or service outcome.

Pickling

Question to resolve

Are oxide, scale, weld heat tint or another surface condition outside a passivation-only scope?
What material-removal boundary, protected features and inspection evidence require review?
Do not assume passivation alone addresses every condition.

Electropolishing

Question to resolve

Is intentional surface modification part of the stated objective?
What dimensional, finish, edge and functional-surface review is needed?
Do not assume it substitutes for another controlled scope.

Boundary: The output does not choose a chemical route, determine whether a treatment is needed, or make a performance claim. It is not a process approval, work instruction, or application-suitability decision.
