摘要： Complexable polymeric binder-lubricant blends are disclosed for production by powder metallurgy techniques of ferrous compositions with remarkably high green strength upon compaction, or soft magnetic ferrous powder/resin composites with improved processability and magnetic properties. An exemplary composition consists of a ferrous powder, a thermoset phenolic resin and poly(ethylene oxide), both polymers exhibiting, when intimately mixed, strong intermolecular acid-base interactions giving rise to an interpolymer complex which imparts a high strength to the resulting ferrous powder compact.

摘要： Post-compaction treatments of iron compacts to improve the mechanical strength of the compacts are provided. Powder is compacted into the desired part. The part is then subjected to a strengthening operation. This operation involves a heat treatment at a moderate temperature combined with an optional resin impregnation. The heat treatment is done at a temperature sufficient to increase the mechanical properties of the compact while maintaining the magnetic losses low for the required application. Impregnation with an insulating binder can be effected to increase the mechanical strength of the part without creating electric contacts between the powder particles.

摘要： The present invention relates to ferromagnetic powders with an electrically insulating layer on iron particles intended for the manufacture of components having improved soft magnetic properties at low and medium frequencies. The invention comprises an iron powder coated with a dielectric insulating layer comprising boron bearing compounds to form an insulated ferromagnetic powder. The present invention also relates to a method of making these insulated ferromagnetic powders. The present invention further relates to a method of synthesizing a product made from insulated ferromagnetic powders via a post-heat treatment at a moderate temperature (300° C. to 700° C.), to form a glass-like coating which acts as an electrical insulator. A preferred embodiment of the present invention is obtained when small amounts of alkali bearing compounds are added to the precursors to modify the coating chemistry and significantly increase the electrical resistivity after heat treatment.

摘要： An alloy having a low reactivity towards certain high temperature superconducting materials at temperatures up to about 10.degree. C. lower than the melting point of the alloy. The alloy is a ternary silver-based alloy consisting, by weight, of 0.5-9% palladium, 20-40% gold, balance silver. Using the alloy and a superconducting material of the type R-Ba-Cu-O, where R is yttrium or a rare earth element, composite conductors can be formed at temperatures equal or higher than the temperature of peritectic decomposition of the superconductor. The alloy may also be used as a buffer layer or cladding material on substrates having unacceptably high reactivity towards the superconducting material.
