基于金属粉末微波烧结技术的研究现状
|
摘要
由于微波具有高温、高焓、高的化学反应活性、反应气氛及反应温度可控等特点,非常适合制备纯度高、粒度小且粒度分布均匀的新性能材料。本文综述了微波烧结技术对合金性能的影响因素,重点阐述了微波烧结铁基材料、微波烧结软磁铁氧体材料、微波烧结高密度合金、微波烧结硬质合金和微波烧结难熔金属对材料的性能的影响。结果表明,微波烧结相对于常规烧结大大的加快了反应的速度,且烧结材料的各项性能都远远高于常规烧结,且烧结过程的生产周期变短,降低了能耗,提高了生产的效率。
Since microwave has the characteristics of high temperature, high enthalpy, high chemical reactivity,reaction atmosphere and controllable reaction temperature,it is very suitable for the preparation of new performance materials with high purity,small particle size and uniform particle size distribution. This paper summarizes the influence factors of microwave sintering technology on the properties of the alloy,focusing on microwave sintering of iron-based materials,soft ferrite materials,high density alloy,cemented carbide and difficult to melting metals,and on influence of microwave sintering on performance of the material. The results show that compared with the conventional sintering,microwave sintering can greatly accelerate the reaction speed,improve properties of the sintered materials,shorten production cycle,reduce energy consumption and enhance production efficiency.
