Abstract: A method and system are disclosed for impregnating a porosity of a part with sealant without immersing the part in sealant or using a known batch process. At least one fill source and at least one drain source are connected to the part, wherein the fill source and drain source are each in communication with a porosity of the part. In one aspect a vacuum is applied through the fill source and through the porosity, and sealant is then released into the porosity. Pressure can be applied to the porosity after the sealant is released into the porosity to assist in pushing the sealant into the porosity. Excess uncured sealant can be removed by injecting water into the porosity and then drawing out the water with the excess sealant. Heated water may be introduced into the porosity to cure the sealant if the sealant requires heat to cure.

Abstract: A device and method for curing solvent-impregnated (or saturated) graphite parts includes a cure module, wherein graphite parts saturated with a sealant are positioned in the cure module. Water is then placed in the cure module until the graphite parts are immersed in the water. The cure module is then pressurized to between 1 bar-20 Bar or more and the temperature of the water is maintained at any temperature from 90° C.-225° C. or more.
