Dr. Jennifer Williams, a NASA research chemical engineer, displays two fatigue samples that will be tested in the Plasma Rapid Oxidation Technique for Extending Component Tenability (PROTECT) experiments inside the Prototype Laboratory at NASA’s Kennedy Space Center in Florida on Nov. 2, 2022. Plasma electrolytic oxidation is a surface coating technology that produces oxide layers on the surface of light metals and their alloys to improve their performance characteristics. These coatings are tailored to provide a combination of characteristics such as corrosion protection, wear resistance, thermal management, extreme hardness, and fatigue performance. PROTECT is expected to demonstrate a 10 percent improved fatigue performance and a 70 percent improvement in corrosion characteristics on the interior of treated 3-D printed metallic parts when compared to non-treated parts. PROTECT could be applied to spacecraft and launch vehicles.
