Provided are a mixed nano-lubricating oil and a method for preparing the same. The method for preparing a mixed nano-lubricating oil includes the steps of: (a) preparing a mixed solution by adding and mixing a nanopowder and a dispersant to a solvent and pulverizing the nanopowder to a primary particle level; (b) modifying the surface of the nanopowder; (c) substituting the solvent of the mixed solution to a lubricating oil; and (d) mixing at least two nano-lubricating oils prepared using physically and chemically different nanopowders. According to the present invention, it is possible to improve the wear resistance and the load resistance at the same time by mixing at least two kinds of lubricating oils having excellent wear resistance or load resistance.

The present invention provides a grease composition capable of effectively preventing a rolling surface of a bearing from having hydrogen brittleness-caused peeling, a grease-enclosed bearing in which the grease composition is enclosed, and a rotation-transmitting apparatus with a built-in one-way clutch in which the grease composition is enclosed at a sliding portion. The grease composition contains a base grease consisting of a base oil and a thickener; and an additive added to the base grease. The grease composition prevents a frictional wear surface of the sliding portion or a newly generated surface consisting of iron or the like exposed owing to wear from being peeled owing to hydrogen brittleness. The additive contains a bismuth-based additive or a magnesium-based additive. The bismuth-based additive consists of at least one of inorganic bismuth and organic bismuth not containing a sulfur component. The magnesium-based additive consists of at least one of inorganic magnesium and organic magnesium. The grease-enclosed bearing encloses the above-described grease composition.

An interface suspension facilitates laser welding of a first metal having a first zinc coating to a second metal having a second zinc coating. The interface suspension includes a petrolatum base and a plurality of spherules suspended in the petrolatum base. The interface suspension melts when the zinc coated metals are welded to allow the plurality of spherules to maintain a gap between the first and second metals. This allows vapors of zinc to escape through the gap during the weld process to maintain the integrity of a resulting weld.
