摘要：
This article concerns functionally gradient materials (FGM) realized by laser sintering. Layers of Fe rich and Cu rich powders were compacted first and then laser sintered to obtain multilayer samples with smooth composition gradients. Microanalysis profiles on the cross sections of sintered samples show gradual increasing of Cu content and decreasing of Fe content. The laser sintered FGM contain several phases such as free graphite, ferrite, pearlite, Cu-Ni solid solutions, austenite, alpha-Cu phase, delta-phase (Cu31Sn8), epsilon-phase (Cu3Sn) as well as eta-phase (Cu6Sn5). The experimental results show good wear resistance and toughness properties of the laser sintered FGMs.
