Contact-pair engineering for friction, wear, lubrication, transfer films and debris across atmosphere, vacuum and temperature extremes.
Contact-pair engineering for friction, wear, lubrication, transfer films and debris across atmosphere, vacuum and temperature extremes. Selection must remain tied to exact material identity, architecture, process state and service environment.
Manufacturing route, constituent condition, interfaces, joining or consolidation state, defects and quality controls remain part of the engineering record.
Temperature, chemistry, radiation, vacuum, moisture, cyclic loading, aging and other relevant degradation drivers are tracked as configuration-dependent conditions.
Property values require units, specimen/process condition, test method, source provenance, evidence level, maturity and application-specific acceptance criteria.
| Control area | Required content |
|---|---|
| Material identity | Exact composition, grade, constituent architecture, product form and supplier designation where applicable. |
| Process / condition | Manufacturing route, heat treatment or cure, consolidation, surface state, porosity/defect state and relevant history. |
| Performance fields | Only source-supported property values with units, temperature/environment and test basis; no rendering-derived design data. |
| Failure / degradation | Relevant fracture, fatigue, creep, wear, oxidation, corrosion, aging, interface or environment-driven mechanisms. |
| Evidence / availability | E0–E5 evidence grade and A0–A5 availability state retained with source provenance and maturity controls. |
Adhesives, brazes, solders, diffusion bonds and mechanical interfaces treated as graded material systems, not geometric afterthoughts.
