Abstract
A lubricant composition for thread or bearing surface operated at high temperature and stress load conditions, a thixotropic mixture including a Jojoba base vehicle, metallic and non-metallic particulates, a metallic component for wetting the stressed thread or bearing surfaces, together with non-metallic particulates that coat the stressed surfaces and other metallic particulate solids also wet by the metallic component. The lubricating vehicle retains the composition in place under extremely high temperatures without gassing off so that the particulate elements function properly to permit relative sliding motion of the stressed surfaces.
Claims15
A lubricant composition for thread and bearing surfaces to be exposed to high temperature and stress loading which comprises about 15 to 50% thickened jojoba oil as a vehicle, about 0.5 to 10% indium, in solid particulate form, metallic and/or semi-metallic lubricating particulates, and about 0.40 to 10% non-metallic particulates.
A lubricant composition particularly adapted for application to highly stressed thread or bearing surfaces to be exposed to high temperatuires, comprising essentially about 36% of a Jojoba based grease, about 16% of powdered graphite, about 29.5% lead powder, about 12.2% zinc dust, about 3.3% copper flake, about 1% of carbon monofluoride, about 1% of solid particulate aromatic polyester and about 1% of indium powder, by weight.
A composition for lubricating thread and bearing surfaces to be highly stressed and subjected to high temperatures comprising a grease having a principal oil constituent with a fume point in excess of 650.degree. F., a major amount of metallic and/or semi-metallic particulate distributed within the grease, and less than 5% of a metallic powder having the property of diffusing on the surfaces to be lubricated and on the particulates.
