Describe the conversion-coating requirement
Alodine is commonly used as a trade name for chemical-film or chromate-conversion coating, but the exact customer requirement should be identified by its specification and revision. State the substrate and the required finish condition. Do not assume two similarly named treatments have identical acceptance criteria.
Show what must be protected or inspected
Mark threads, fits, electrical contact areas and surfaces that must remain untreated or receive another finish. Identify dimensions to inspect and whether measurement occurs before or after treatment. List any color, appearance, documentation or packaging requirements only when they are part of the approved scope.
Keep compliance claims tied to evidence
Requirements for restricted substances, industry approvals or customer qualification must be supported by the applicable specification and project evidence. Include the governing documents in the RFQ and request confirmation before release; a generic coating name is not proof of compliance.
For general finish planning, see CNC surface finishing services. To compare a different treatment, see anodizing services for machined parts.
RFQ details
- Material grade and part drawing revision
- Exact chemical-film specification and required condition
- Masking, contact surfaces and critical dimensions
- Inspection method and required records
- Quantity, packaging and approval requirements
Confirm the process and acceptance basis for the actual part before order approval.
