MOLYBDATE-BASED COMPOSITION AND CONVERSION COATING

摘要

Disclosed herein are embodiments of a molybdate-based composition and a conversion coating obtained therefrom that can replace conventional and toxic chromate-based conversion coatings in a variety of applications and industries. The molybdate-based composition provides conversion coatings that exhibit anodic inhibition and rapid repassivation when applied to objects, such as metal -based objects, and do not contain hexavalent chromium. The molybdate-based composition and conversion coating can be used to reduce corrosion. Embodiments of methods of protecting objects, such as metal surfaces, with the molybdate-based conversion coating also are disclosed.
