Abstract: The present invention relates to additives for use in lubricant compositions to processes for producing the additives, and to the use of the additives in lubricants and in systems that are lubricated. More specifically, the additive includes a capped particle (10) comprising: (i) one or more core particles (20) wherein the core particle is an inorganic particle having a dimension less than about 5 μm; and (ii) one or more multi-block copolymers (30) attached to the inorganic particles, wherein the multi-block copolymer comprises a) at least one nonpolar polymer block (51 ); b) at least one first polar polymer block (41 ); and c) at least one second polar polymer block (42); wherein the nonpolar polymer block is interposed between the first polar polymer block and the second polar polymer block, the first polar polymer block is attached to the core particle, and at least a portion of the second polar polymer block is not attached to the core particle. When used in a lubricant to lubricate a metallic surface of a workpiece (60), the capped particle preferably adhere to the metallic surface of the workpiece.
