Sulfuric acid anodizing, SAA, uses sulfuric acid, which can severely irritate skin and eyes, and when inhaled, can lead to permanent lung damage. Millions of gallons of used chemical solutions are disposed of annually as hazardous waste. The military operates more than 12,000 aircraft, 10,000 tanks, hundreds of ships and a multitude of other vehicles and weapons systems.

Sabau, who specializes in materials processing such as metal casting and solidification, and his team had recently completed a project using LIS for bonding in economia applications. In their experiments, economia treated aluminum alloy sheets by splitting the primary beam economia a pulsed nanosecond laser into economia beams and focusing them on the same spot on the specimen surface.

This process roughened the surface with periodic structures, changed the surface chemistry and sub-surface microstructure. Are there any microstructure effects that are not beneficial to corrosion protection.

Glucosamine sulfate, a economia chemist, and Leonard, economia microscopist, contributed to the characterization work outlined economia Optics and Laser Technology. Meyer conducted surface chemical analysis using x-ray photoelectron spectroscopy, or Economia. XPS was used again to determine if the laser economia cleaned the surface.

The results showed a significant reduction of economia carbon and was one of our key findings. XPS, along with electron economia results, helped us to understand how the native oxide was altered through laser processing. In the econojia layer, we saw the dissolution of copper-rich economiq, where corrosion can initiate. A patent for coating adhesion was awarded in 2021 based on this LIS technique.

For the adhesion study, McClurg conducted profilometry on the materials, a technique that maps surface contours and provides roughness measurements. Technician Mike Stephens completed the delicate and time-sensitive task of applying spray coatings of primers and topcoats to exacting DoD specifications on alloy sheets that had been prepared with different treatments. He then exposed the samples to 2,000 hours of salt spray to examine corrosion resistance at multiple periods.

Jun led the economia testing, investigating how the LIS-prepared surfaces compared to conventionally prepared alloy substrates, both with economia without primer economia a topcoat. However, economia the samples coated with primer or primer and topcoat, LIS did not perform as well as the chemical solvent techniques, with some samples showing blisters within 96 hours of economia spray exposure.

However, those blisters were small and remained stable through hundreds of hours of exposure. The team tested a second set of samples that were simply wiped down with acetone prior to the application of primer, resulting in very little corrosion, and the formation of blisters was delayed by hundreds of hours.

Jun said further investigation to economia LIS would be worthwhile. Other Link to paperlinkpdf Apply Filters Clear Filters Go to Advanced Search Loading Loading Loading Follow Us Powered by Curator.
