Start with the approved specification
Aerospace surface-treatment work must be reviewed against the component specification and customer approval requirements. A general wear-resistance explanation does not establish suitability for flight hardware.
Check supplier and process scope
Where process accreditation is required, check the current scope and validity. Accreditation, customer approval and individual component acceptance are different questions.
Require documented outcomes
Service-life improvements, cost savings and project success need traceable results. This article discusses purchasing questions and does not describe a documented DVS aerospace job.
Prepare the technical review
Provide the drawing, material, applicable process and inspection specification, part condition and approval requirements. Confirm the approved route before changing a coating or restoration process.
