摘要： A method for producing a composite part. The method comprises compacting a powder composition comprising a lubricant into a compacted body; heating the compacted body to a temperature above the vaporisation temperature of the lubricant such that the lubricant is substantially removed from the compacted body; subjecting the obtained heat treated compacted body to a liquid polymer composite comprising nanometer-sized and/or micrometer-sized reinforcement structures; and solidifying the heat treated compacted body comprising liquid polymer composite by drying and/or by at least one curing treatment.

摘要： The present invention concerns a ferromagnetic powder composition comprising soft magnetic iron-based core particles, wherein the surface of the core particles is provided with a first inorganic insulating layer and at least one metal-organic layer, located outside the first layer, of a metal-organic compound having the following general formula: (R
1 [(R
1 )x(R
2 )
y (MO
n-1 )]
n R
1 , wherein M is a central atom selected from Si, Ti, Al, or Zr; O is oxygen; R
1 is a hydrolysable group; R
2 is an organic moiety and wherein at least one R
2 contains at least one amino group; wherein n is the number of repeatable units being an integer between 1 and 20; wherein the x is an integer between 0 and 1; wherein y is an integer between 1 and 2; wherein a metallic or semi- metallic particulate compound having a Mohs hardness of less than 3.5 being adhered to at least one metal-organic layer; and wherein the powder composition further comprises a particulate lubricant. The invention further concerns a process for producing the composition and a method for the manufacturing of soft magnetic composite components prepared from the composition, as well as the obtained component.
