The impregnated particles that lie below the protective oxide layer remain available throughout the life of the component in the event the original oxide layer becomes worn or damaged, wherein a renewed protective oxide is formed in such regions due to the presence of the impregnated particles.

    Abstract: Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.

  • Publication number: 20130276563
    Abstract: The present invention provides a grease composition which contains a small amount (not more than 0.06 wt %) of molybdenum and yet is capable of achieving an excellent low friction property when mechanical parts in which the grease composition has been packed are operated under a severe sliding condition in which they are subjected to a high speed and a high contact pressure. The present invention also provides a bearing, a universal joint, and a linear motion device in which the grease composition of the present invention is packed. A grease composition (7) is packed inside a grease-packed bearing (1) in such a way that the grease composition (7) is applied to at least the circumference of each rolling element (4). The grease composition (7) contains base oil, a thickener, and an additive. The additive includes molybdenum dithiocarbamate and sodium dithiocarbamate. The content of the molybdenum for the whole weight of the grease composition (7) is set to not more than 0.06 wt %.

    Abstract: A sliding structural member is provided which achieves a good low frictional property. A DLC film 2 containing hydrogen is provided on one member 11 between members sliding against each other, and the one member and a counterpart member 12 are combined in such a way that the DLC film 2 provided on the one member 11 slides against the counterpart member via a lubricant 3 to which organic molybdenum compound and compound containing zinc and sulfur are added as an additive. A root mean square roughness of a surface of the DLC film 2 is set in a range from 5 nm or more to 25 nm or less, and hydrogen content of the DLC film 2 is set in a range from 4.5 at % (atomic %) or more to 30 at % or less.

  • Publication number: 20130130014
    Abstract: A method and chemical composition and material structure for improving fretting wear in substrates, particularly carbon-carbon composite (CCC). The invention relates to trilayer coatings, comprising a base of hard ZrO2, a middle layer of Al2O3, and atop layer of lubricious ZnO. The coatings of the present invention exhibit conformality and pore-filling down to approximately 100 microns into a carbon-carbon composite to which they are applied. The methods for preparing the coatings include a chemical vapor infiltration route, such as an atomic layer deposition (ALD) process, to uniformly and conformally coat the porous and open structure of CCC with a solid lubricant trilayer of ZnO/Al2O3/ZrO2 that results in significant improvement (65%) in fretting wear.
