摘　　要：应用CO_2激光器对Fe-C-Cu-MoS_2粉末冶金坯料进行烧结,在烧结期间元素发生扩散,形成了微细的Fe_3C和CuMo_2S_(5-x)相。该法烧结成的材料具有理想的组织和性能。直径为10mm的坯料可在5分钟内充分透烧。CO2 laser beam was used to sinter green compacts made of alloy powder. Elements were analyzed using EDS and X-ray diffractometer. It was found that the element diffusion occourred during the laser sintering, forming refined Fe3G and CuMO2S5-a phases. Green compaets with a diameter of 10mm can be fully sintered within omin.
