Reanodized
Reanodized is a term used to describe the process of applying a new anodic oxide coating to aluminum alloys after the previous anodized layer has been damaged, degraded, or is no longer satisfactory. The reapplication aims to restore corrosion resistance, wear resistance, and surface appearance, and may also enable color restoration or change.
The process generally begins with cleaning and evaluation of the existing coating. If the old anodic layer
Applications include architectural extrusions, aerospace components, automotive parts, and consumer electronics housings. Reanodizing allows color matching
Considerations include cost, process control, alloy compatibility, and environmental concerns due to acid baths and effluents.
