Abstract: A particulate composite lubricant for powder metallurgy comprises: first discrete particles comprising at least about 90 wt % of a fatty primary monoamide wax, being substantially free of fatty bisamide wax, and being at least partially coated with metal oxide nanoparticles and second metal-stearate free discrete particles comprising a fatty bisamide wax. A particulate composite lubricant for powder metallurgy can comprise: a Montan acid ester wax and at least one fatty amide wax comprising at least one of a fatty monoamide wax and a fatty bisamide wax.

Abstract: A method for enabling cold spray of steels, particularly transformation hardenable steels including tool steels, has been made possible by: heat treating steel powder while agitating the powder to limit agglomeration and particle growth; cooling it slowly enough to avoid retransformation hardening; and protecting the powder from cold working or retransformation hardening until cold sprayed. Surprisingly the softening, as well as the agglomerated morphology of powders, has been found to allow for deposition of steel powders. Furthermore, the cooling has been found to be possible within 8 hour heat treatments, and high density, and reasonably high deposition efficiencies have been achieved. Water- and gas-atomized starting powders have been treated and cold sprayed.

Abstract: A particulate composite lubricant for powder metallurgy can comprise: a Montan acid ester wax and at least one fatty amide wax comprising at least one of a fatty monoamide wax and a fatty bisamide wax. It also relates to a process for producing a powder composition for powder metallurgy, comprising: adding the particulate composite lubricant in a concentration ranging between 0.1 wt% to 5 wt%, based on a total weight of the powder composition, to a metal-based powder; and to a metallurgical powder composition, comprising a metal-based powder admixed with the particulate composite lubricant.
