文摘

The structure and physicomechanical properties of materials produced from copper-clad iron powder with 0.3% C are investigated as a function of the sintering temperature, the copper concentration, the method of coating application, and the heat treatment of the copper coatings. The use of copper plating (0.5⎯2.0% Cu), when the reduction of the coatings is combined with the sintering of the parts, activates compaction (with 1.6% decrease in the porosity) and alloying. The mechanical properties of the steel may be increased by a factor of 1.4–1.7 relative to steel made from mixtures of micropowders.
