Abstract: The present invention relates to nanoparticles suitable for use in lubricants, prepared from an activated complex comprising a copper(II) salt and one or more further inorganic metal salt(s), and combined with an organometallic salt composition comprising a copper salt of one or more long chain monocarboxylic acid(s). The invention also relates to a metal-plating additive system and a lubricant additive composition, both comprising said combination of salt composition and activated complex.

Abstract: The present invention relates to a method of pretreatment of a metallic substrate for a subsequent metal cold forming process, said method comprising at least steps (1) and (2), namely providing at least one substrate having at least one surface at least partially made of at least one metal (step (1)), contacting the at least one surface of the substrate provided in step (1) with an aqueous lubricant composition (B) (step (2)), wherein the aqueous lubricant composition (B) comprises besides water at least constituents (b1) to (b4) and optionally (b5), namely as (b1) at least one homopolymer and/or copolymer being prepared by polymerization of at least vinyl pyrrolidone as at least one monomer, wherein (b1) has a polydispersity index (PDI) in a range of from 1.5 to 8.0, as (b2) at least one wax, as (b3) at least one defoamer,and as (b4) (i) oxalate anions and/or phosphate anions or (ii) calcium cations, chloride anions and hydroxide anions, as well as optionally Fe(III) ions as (b5), wherein (b5) is present in case at least oxalate anions are present as (b4), a pretreated metallic substrate obtainable by the inventive method, a method of cold forming of a metallic substrate and an aqueous lubricant composition (B) as defined above.
