QUALITY / CORROSION AND COATING INSPECTION
Coating and Corrosion Inspection for NdFeB Magnets
Align coating choice, corrosion exposure, visual condition and dimensional allowance with the quality plan for custom NdFeB magnets.
Drawing-led review preferred. A clear written requirement can start the discussion when a drawing is not ready.
ENGINEERING SNAPSHOTKeep the requirement visible from review to release.

01 / INPUTS FOR A COATING PLAN
Start with exposure and fit.
A coating inspection plan needs the operating environment, contact conditions, selected treatment, critical dimensions and appearance expectations in view.
Environment
Describe exposure, humidity or contact conditions.
Treatment
State the selected coating or requested route.
Fit
Identify dimensions affected by the finished surface.
Appearance
Clarify visual condition and acceptance expectations.
02 / INSPECTION FOLLOWS THE COATING BASIS
Keep finishing connected to production.
The quality plan should reflect how the coating was selected, how the part was prepared and which surfaces control the assembly. Coating is reviewed with the manufacturing route, not after it.
Preparation
Surface condition before treatment.
Coverage
Finished surfaces and critical features.
Dimension
Allowance at the fit or seating surface.
Condition
Appearance and corrosion-related acceptance.
03 / RELEASE EVIDENCE
Make the acceptance basis explicit.
The RFQ should identify the coating, exposure, visual condition, critical dimensions and any evidence expected for release. Final acceptance remains project-specific.
Coating
Confirm the requested or approved treatment.
Surface
Review appearance and visible condition.
Corrosion
Align evidence with the stated exposure.
Record
Keep the result with the project quality file.
04 / NEXT STEP
Bring the coating acceptance basis.
Share the environment, treatment, critical fit dimensions and appearance or corrosion requirements already known.
Describe
State exposure and operating conditions.
Specify
Identify treatment and critical surface.
Release
Agree the evidence and acceptance basis.
COATING / CORROSION / RELEASE BASIS
Make the finish measurable.
A shared acceptance basis keeps coating, fit and exposure connected.
