Surface Treatment & Coating Inspection
Verify coating thickness, adhesion, and uniformity on protective finishes for aerospace and defense components with edge-native AI vision.
What It Is
Aerospace components undergo critical surface treatments (anodizing, chromate conversion, cadmium plating, thermal spray coatings, and primer/paint systems) that protect against corrosion, thermal degradation, and wear. Every treated surface must be verified for coverage completeness, uniformity, proper color/appearance, and the absence of contamination or defects.
Why It's Hard
- •Subtle color variations in anodize and conversion coatings that indicate process issues are difficult to detect consistently under varying lighting
- •Coverage gaps in hard-to-reach areas, recesses, and internal features
- •Contamination embedded in coatings, inclusions, foreign particles, and process residue that compromise coating integrity
- •Batch-to-batch variation in coating appearance within acceptable limits that confuses rules-based vision
How Overview Solves It
Coverage verification: AI segmentation confirms complete coating coverage and flags bare spots, thin areas, and overspray.
Color consistency analysis: The AI learns the acceptable color range for each coating type and flags parts that fall outside spec, even subtle shifts that indicate process drift.
Contamination detection: Identify foreign inclusions, bubbles, and process residue embedded in coatings before parts advance to assembly.
Frequently Asked Questions
Can Overview measure coating thickness?
Overview provides visual assessment of coating uniformity and identifies areas of suspected thinning based on color/appearance variation. For precise thickness measurement, it complements eddy current and ultrasonic thickness gauges.
How does it handle different coating types?
You train separate models for each coating spec. The AI learns what “good” looks like for each process (anodize, primer, topcoat, etc.) and flags deviations specific to that coating.
