Thermal conductivity of Cu7.2Ni1.8Si1Cr Copper alloy produced via SLM and ability of thin-wall structure fabrication
Popis výsledku v původním jazyce
Three parts - a disk with inner holes and two cylinders with thin-wall web of 0.325 mm and 1.625 mm - were produced by Selective laser melting technology from a copper alloy Cu7.2Ni1.8Si1Cr powder. Based on the previous experience with this copper material, the fabrication was successfully processed with up to 5 % dimensional accuracy according to CAD model. The fabricated samples were tested in an experimental thermo-vacuum chamber to reveal the material thermal conductivity since no data are freely available. Based on the reference samples testing, the evaluation process was upgraded by considering a heat transfer by radiation. The measured thermal conductivity of the SLM produced alloy Cu7.2Ni1.8Si1Cr was 3.4 times lower than the value of a bulk material AMPCOLOY 944 with a similar chemical composition.
