The technology seeker is seeking innovative technologies capable of efficiently and completely removing oxides from Advanced High Strength Steel (AHSS) surfaces and welded areas while promoting surface corrosion inhibition.
The solution should be able to be incorporated into a standard electro-deposition coating process (e-coat). Some AHSS are prone to high surface corrosion, forming a thicker oxide formation at welded areas. This condition may, therefore affect the adhesion of the anti-corrosion coating system, ultimately causing painted components to be more prone to corrosion.
The technology seeker produces a variety of structural steel assemblies by encompassing manufacturing processes in forming, gas metal arc welding (GMAW) and painting. The last of these processes involves protecting the assemblies against corrosion through a system involving cleaning, rinsing, phosphatizing and an E-coat deposition. The whole painting process is done by fully immersing the assemblies in tanks for the pre-treatment and E-coat deposition stages at specified cycle times, followed by curing in an oven.
Cleaning AHSS becomes critical due to these assemblies’ characteristics:
Therefore, the technology seeker is interested in technologies that can demonstrate their solution’s cleaning effectiveness through a scalable process and partners capable to prove their solid technology, expertise, and know-how on this challenge.
The technology seeker will consider for advancement an approach that meets performance criteria with acceptable economics and pathway to commercialization. While commercially available technologies are of primary interest, we will also consider maturing technologies with a reasonably short timeline to commercial viability.
The successful technology will:
• Allow a 70 assembly-per-minute submersion process;
• Will be compatible with carbon steels, coated, galvanized, galvannealed steel and aluminum;
• Have no negative impact on the steel substrate;
• Be easily implementable into existing e-coat painting lines
• Be robust and repeatable
