COATING

Bead Blasted + Chromate Conversion Coating

Bead blasting changes texture before a conversion coating is applied.

ENGINEERING DOSSIER

Define blast preparation, chromate coverage and conductivity-sensitive zones

Blast preparation must not compromise conversion-coating function

Separate cosmetic texture, conductive contacts and zones that require masking.

Sequence and substrate evidence

Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable.

Acceptance belongs to named surfaces

Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation.

Release inputs for Bead Blasted + Chromate Conversion Coating

Specify alloy, media preparation, contact zones, masking, appearance and downstream use.

APPEARANCE AND FUNCTION

Appearance, function and substrate boundary for Bead Blasted + Chromate Conversion Coating

Separate cosmetic texture, conductive contacts and zones that require masking.

Function: Protection, contact, wear or interface role. Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation.

DECISION CONTROLS

Protected interfaces and acceptance controls for Bead Blasted + Chromate Conversion Coating

Sequence and substrate evidence

Confirm substrate alloy/grade, condition and any preparation specific to Bead Blasted + Chromate Conversion Coating. Compatibility must be checked against the named base material, not a generic family.

Acceptance belongs to named surfaces

Map cosmetic zones, datums, fits, threads, electrical contacts, seal lands and areas that must remain uncoated or require controlled build for Bead Blasted + Chromate Conversion Coating.

Release inputs for Bead Blasted + Chromate Conversion Coating

Specify Bead Blasted + Chromate Conversion Coating by process/standard where applicable, appearance reference, coverage, masking map, thickness or build requirement if relevant, and protected critical dimensions.

PROJECT-SPECIFIC DECISION DATA

Finish map before Bead Blasted + Chromate Conversion Coating release

Confirm substrate, preparation, appearance/function, protected zones and inspection evidence; do not infer acceptance from the finish name alone.

Decision item	What must be resolved	Evidence at release
Blast preparation must not compromise conversion-coating function	Separate cosmetic texture, conductive contacts and zones that require masking.	Reference, texture, color or toolpath
Sequence and substrate evidence	Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable.	Protection, contact, wear or interface role
Acceptance belongs to named surfaces	Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation.	Coverage, masking and critical features
Release inputs for Bead Blasted + Chromate Conversion Coating	Specify alloy, media preparation, contact zones, masking, appearance and downstream use.	Coverage, masking and critical features

INSPECTION AND ACCEPTANCE

Inspect Bead Blasted + Chromate Conversion Coating against the named reference and functional interfaces

Inspect Bead Blasted + Chromate Conversion Coating against the agreed sample/reference, coverage and surface zones; verify masked interfaces, thread function, fit-sensitive dimensions and any required adhesion/corrosion evidence.

Geometry, access, edges, recesses and part-to-part variation can affect the result; use a named reference and surface map.

DECISION QUESTIONS

Bead Blasted + Chromate Conversion Coating specification and inspection questions

What must be defined before reviewing Bead Blasted + Chromate Conversion Coating?

Separate cosmetic texture, conductive contacts and zones that require masking. Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable.

Which interfaces need project-specific confirmation?

Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation. Geometry, access, edges, recesses and part-to-part variation can affect the result; use a named reference and surface map.

What should accompany release?

Specify alloy, media preparation, contact zones, masking, appearance and downstream use. Coverage, masking and critical features

PROJECT BRIEF

Bead Blasted + Chromate Conversion Coating finish map and acceptance checklist

Use these page-specific checks to define substrate, preparation, appearance or function, protected zones and acceptance evidence for Bead Blasted + Chromate Conversion Coating. Do not release from the finish name alone.

Pretreatment and substrate — Blast preparation must not compromise conversion-coating function

Separate cosmetic texture, conductive contacts and zones that require masking. Record substrate and pretreatment on a controlled surface map.

Appearance or function — Sequence and substrate evidence

Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable. Attach the named appearance or functional reference used for acceptance.

Masking and acceptance — Acceptance belongs to named surfaces

Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation. Mark masking, fit-sensitive zones and the inspection record required at release.
