Coatings for Solid Rocket Motor Casings. Additionally, prior to application of the zinc phosphate and prior to final painting, the SRM is abrasive blasted to remove the zinc phosphate coating. This process involves nineteen separate steps and results in contaminated blast media, hazardous sludge from vapor degreasing, and chromic acid waste.
BOSS is the application of powdered stainless steel using plasma-arc thermal spray technology.
This will be verified using test panels with various thicknesses of BOSS coating sprayed on to them. IBIT, peel strip and CBIT tests will be performed to evaluate bondline strengths. The application of insulations and liners for solid rocket motors involves 9 separate steps involving the application of wet coatings. All solvents are identified as toxic, hazardous substances or ozone depleting and must be replaced with environmentally compliant alternatives per federal regulations and executive order. This technology is currently used to apply thermal protective insulation to space shuttle components.
