Superfine iron-copper alloy powder and preparation method thereof

Abstract

The invention relates to superfine iron-copper alloy powder and a preparation method thereof. The superfine iron-copper alloy powder is prepared by using ferric oxalate powder at an industrial raw material stage and cupric oxide powder at an industrial raw material stage as raw materials through high-energy ball milling and hydrogen reduction and has a fisher particle size smaller than 1.0 microns and a oxygen content smaller than or equal to 0.5 percent by weight. The invention has the advantages that grains of the superfine iron-copper alloy powder are thinner, the physical and chemical properties are superior, and the manufacture cost is low.

Description

technical field

[0001] The invention relates to the field of metallurgy industry, more specifically, the invention relates to a powder metallurgy product and a preparation method thereof. Background technique

[0002] Iron-copper powder is the raw material for manufacturing iron-copper-based powder metallurgy parts, and has a wide market demand in aerospace, machinery, automobile, electrical appliances and other industries.

[0003] Traditional iron-copper powder preparation methods mainly include: (1) mechanical mixing method, that is, directly mechanically mixing iron powder and copper powder; (2) copper-coated iron powder, that is, coating iron powder with copper by electroless plating (3) Atomization method, that is, adopting first melting iron-copper metal and then atomizing into iron-copper powder.

[0004] The common disadvantages of the iron-copper powders prepared by the above three traditional methods are: (1) the particle size of the powder is relatively coarse a...
