Coating Inspection

What this topic covers

Thickness, adhesion, visual condition and surface preparation evidence.

Core testing ideas

Coating quality involves more than thickness alone.

Substrate preparation, cure and environment can influence long-term performance.

Different coating systems use different test methods and acceptance requirements.

Measurement and method limits

Multiple methods are often complementary because dimensional, surface and internal conditions are different.

Evidence and traceability

Acceptance and qualification requirements should come from the governing product or engineering specification.

Using the result

Testing and inspection evidence should remain connected to material, process and product history.
