Advanced Coatings for Edge Protection

NCMS Project #: 141016

Problem: Corrosion can occur on any metal surface but is typically concentrated in several common areas: sharp edges, joints (welds, fasteners, or dissimilar materials), and complex geometries.  Current specified products are effective in preventing corrosion, however they are not specifically designed to inhibit corrosion in these problem areas.  Protective coatings solutions that specifically target zones at high-risk for corrosion damage would significantly reduce creeping rust and material damage.

Benefit: Protecting material edges, joints, and complex geometries using state-of-the-art primer coating technologies for steel and mixed-metal assemblies across various surfaces can apply to industrial and commercial equipment thus improving lifecycles and sustainment of facilities, and transportation fleets/systems.  A successful project will identify one or more promising primer technologies for providing enhanced edge corrosion protection.

Solution/Approach: Work on this project will target and investigate methodologies for protecting material edges, joints, and complex geometries using state-of-the-art primer coating technologies for steel and mixed-metal assemblies.  Primer formats such as powder, electrodeposited, and conventional liquid applied will be evaluated for their ability to improve corrosion resistance.  Variations of these formats will be investigated such as advances in electrocoat technology and novel metal-rich sacrificial primers.
