Abstract: A structure (200) for containing a volume of lubricant additive gel (10) which is disposed within a mechanical system, in close proximity to a wear critical surface, and which is configured to provide a release of the contained additives into a flow of lubricant over time or as a function of temperature in a site-specific manner to minimize wear or reduce oil oxidation due to harsh operating conditions. The structure defines a cage or capsule with screen or mesh sides (202) having multiple perforations or openings through which the flow of lubricant may circulate. Within the contained volume of the structure (200), additives are disposed in a gel matrix (10), and are release over time or as a function of temperature, through the perorations or openings, in close operative proximity to wear critical surfaces of the mechanical system such as a bearing assembly or gear arrangement.

Abstract: A method of coating spherical components with a coating process in which the spherical components have a surface area includes positioning the spherical components within a containment boundary on a moving member and positioning the moving member within a chamber. The method includes reducing the pressure within the chamber to less than one atmosphere. The method also includes revolving the moving member about a longitudinal axis. The method further includes oscillating the moving member in a direction of the longitudinal axis and commencing the coating process. The oscillating and revolving produce motion of the spherical components within the containment boundary such that an entirety of the surface area of each component is exposed to the coating process.

Abstract: A protective coating C is applied to an inner (2) or an outer (4) member of a rotary fluid bearing by sputtering to minimize scuffing, wear and premature failure of the members (2, 4) during starts and stops of the bearing. The coating C may include titanium, tungsten, chromium, amorphous carbon with or without metallic impurities, and hydrogenated amorphous carbon with or without metallic impurities. One of the members (2) is formed in two sections (10, 12) to accommodate assembly of the bearing and these sections abut at end faces (at 16). Features on each end face (at 16) are imparted to the other end face in a compression coining process to facilitate rapid and repeatable alignment of the two sections (10, 12) when separated and rejoined during subsequent manufacturing steps.
