| titleOfInvention | Liquid oxygen compatible biodegradable dye penetrant compositions and method of dye |
| abstract | Liquid oxygen-compatible water washable substantially biodegradable dye penetrant composition having excellent sensitivity and high stability, for use in non-destructive dye penetrant inspection particularly of parts or mechanical components which are later placed in contact with liquid oxygen, and which are compatible with a wide variety of metals including steel alloys, such composition consisting essentially of an organic dye, preferably a fluorescent dye, a carrier or solvent for said dye, in the form of certain oxyalkylated alcohols, preferably ethoxylated linear alcohols,particularly the biodegradable nonionic surfactants comprised of ethoxylates of a mixture of secondary alcohols having linear alkyl chains of from 11 to 15 carbon atoms, and an average of from 3 to 12 moles of ethylene oxide, and a nonhalogenated solvent which is volatile at room temperature, e.g. a ketone such as methyl ethyl ketone or acetone, or a suitable alcohol such as ethyl alcohol. In the method of application of the dye penetrant composition, such composition is applied to the surface of an object containing cracks and flaws, and following rapid evaporation of the solvent, water is applied to the surface of the object to remove excess liquid dye penetrant composition from the surface without removing such penetrant from the cracks and defects, and with or without a developer, the surface of the object is viewed under suitable lighting conditions, e.g. ultraviolet or black light when the dye in the penetrant is a fluorescent dye, to locate any cracks or defects in the surface of the body as indicated by colored traces from the dye penetrant remaining in the cracks and flaws. Upon evaporation of the solvent, residual dye penetrant remaining on the object surface is rendered nonsensitive or nonreactive with liquid oxygen. |
