APPLIQUES PROVIDING CORROSION PROTECTION

摘要

Increasingly stringent environmental restrictions make it challenging to apply coatings (i.e., paint) by conventional processes like spray painting because of the volatile solvents and hazardous pigments. The environmental scrutiny is particularly focused upon conventional corrosion protection surface treatments, especially chromated primers and conversion coatings. We apply appliqués to provide a vapor barrier over the substrate to provide corrosion protection. We can make curved appliqués on a family of molds of different Gaussian curvature and thereby avoid making a "splash" mold of the surface of interest to create the appliqués. Using curved appliqués reduces ridges, creases, or gaps that sometimes otherwise occur with attempts to a cover a surface with complex curvature with flat (planar) appliqués.
