For this purpose different copper contents were used (3, 8 or 12wt%) and the oxygen content of the coated powders was measured. After sintering at 1120 degrees C for 60 minutes in hydrogen flow, microgradient structures were observed. The samples were investigated by light optical microscopy and tested under bending and tensile loads. Young's Moduli were calculated from resonance frequencies. The copper-coating of the iron powder results in an improvement of all properties, owing to a more homogeneous copper distribution and the absence of large secondary pores, compared to specimens made from mixtures of iron and copper powders. In the case of Fe-12Cu (coated), all determined properties tend to result in a maximum: highest sintered density (7,33 g/cm(3)), tensile strength (489 MPa), transverse rupture strength (1098 Pracoviště Ústav struktury a mechaniky hornin Kontakt Iva Švihálková, svihalkova@irsm.cas.cz, Tel.: 266 009 216 Rok sběru 2018
