Title
(EN) Insitu metal matrix nanocomposite synthesis by additive manufacturing route
(ZH) 通过增材制造途径合成原位金属基质纳米复合物
Abstract
(EN)
A unique and novel additive manufacturing route has been proposed to form a thermally stable in-situ metal matrix nano composite by interfacing reactive plasma in the selective laser melting process chamber. The proposed route gives very high compositional freedom, i.e. nitrides, carbides, oxides, silicides and other ceramics with different stoichiometries can be reinforced in nanoscale in any metallic matrix. Components with such a nanocomposite structure display superior high temperature structural properties.

提出了一种独特且新颖的增材制造途径,通过在选择性激光熔化工艺室中接入反应性等离子体来形成热稳定的原位金属基质纳米复合物。所提出的途径提供非常高的组成自由度,即,具有不同化学计量比的氮化物、碳化物、氧化物、硅化物和其他陶瓷可以在纳米级上掺入任何金属基质中。具有这种纳米复合结构的部件展现出优异的高温结构性能。
