Publication number: 20140023553Abstract: A corrosion prevention and control composition and method comprises combining primarily two-component polyurethane foam formed by reacting polyols with an isocyanate compound, and a 2 to 10 percent by weight of either an organic or inorganic gas-phase corrosion inhibitor. The closed cell foam provides a barrier protection for the underlying corrodible surface, while the inhibitor protects the metal from the absorbed moisture vapor, thereby preventing corrosion from occurring at the foam/metal interface. The resulting foam and inhibitor composition maintains better adhesion to the underlying corrodible structure in corrosive environments.Type: ApplicationFiled: November 5, 2012Publication date: January 23, 2014Applicant: U.S. Army Research Laboratory ATTN: RDRL-LOC-IInventor: U.S. Army Research Laboratory ATTN: RDRL-LO

Patent number: H2287Abstract: A structural low carbon steel in combination with and in contact with an aqueous MDEA solvent that includes as an amine-based chemical additive. When mixed with MDEA solvent to form a MDEA solution, the MDEA-based solution in contact with carbon steel reduces the corrosion rate of low carbon structural carbon steels having a carbon content greater than about 0.18% by weight is significantly reduced when the concentrations of CO2, O2 and heat stable salts (HSS) are controlled below critical amounts. The MDEA solution, when controlling the concentrations of CO2, O2 and HSS below critical amounts, suppresses the corrosion of carbon steel having a carbon content greater than about 0.18%. A smooth surface finish further suppresses the corrosion of the low carbon structural steel. When the CO2, O2 and HSS are maintained below critical values, a low carbon structural steel having a micropolished surface finish displayed improved corrosion resistance.Type: GrantFiled: May 12, 2011Date of Patent: December 3, 2013Inventors: Frederic Vitse, Stephen A.
