Fused Silicide Coating Application – R512E

The contract requires the application of HITEMCO R512E fused silicide coating, composed of Si-20Fe-20Cr, to thirty specimens made of refractory alloy using the slurry-fused diffusion process. The coating must achieve a precise thickness between 0.003 inches and 0.005 inches, demanding strict control and quality assurance to meet dimensional and compositional specifications. This work is classified as a subcontract under NAICS code 332813 and is issued by the NASA Shared Services Center on behalf of the National Aeronautics and Space Administration. The solicitation was posted on July 23, 2026, with responses due no later than July 28, 2026, at 9:00 PM, indicating a tight turnaround for technical proposal submission and readiness for execution. The performance location and point of contact details are not specified, but the nature of the coating process and material composition suggest applications in high-temperature aerospace environments requiring enhanced oxidation and corrosion resistance.
