| Abstract: | A series of experiments are carried out with selective laser sintering (SLS) for copper, copper-nickel powder materials. The phenomena of the sintering process is analyzed, the influence of technological parameters is discussed in detail. By means of SEM with energy spectrum system and X-ray diffraction spectrum, the morphology of the microstructure and the compositions of the different zones are analyzed, the mechanism of the laser sintering metallic powders is preliminarily explored. All those above lay the foundations for the forming metal parts by laser sintering metallic powders. |
