Material response
The coating and substrate interact thermally. Absorption, thickness, conductivity and allowable temperatures all influence the feasible processing window.
Geometry matters
Edges, recesses, overlaps and varying thermal mass can produce different local conditions. Representative geometry should be introduced before production assumptions are made.
Measure what matters
Choose measurement and inspection methods suited to the actual material and required outcome. Process settings alone are not evidence of coating acceptance.
