摘要
从微波场对金属粉末的电磁作用及微波场中金属粉末的烧结行为等角度,综述了国内外金属粉末微波烧结机理的研究进展。在电磁作用方面,总结了热效应与非热效应对于烧结过程的影响,热效应对烧结的影响主要包括微波加热电磁功率的损耗和电磁聚焦现象,非热效应对烧结的影响主要是放电效应和磁力效应。归纳了烧结颈长大过程中的物质迁移方式及烧结颈生长机理,材料种类和工艺参数对物质迁移方式产生影响,烧结颈的生长过程同温度场及电磁场密切相关。本文在综述了现有研究进展的基础上,分析了目前研究的不足与欠缺,展望了金属粉末微波烧结机理未来的研究方向。
The research progress on the microwave sintering mechanism of metal powders was reviewed in this paper from the aspects of the electromagnetic effect on metal powders in microwave field and the sintering behavior of metal powders in microwave field.In the electromagnetic effect,the influences of thermal effect and non-thermal effect on sintering behavior were introduced,respectively.The thermal effects of sintering mainly included the electromagnetic power loss caused by microwave heating and the electromagnetic focusing phenomenon.The non-thermal effects mainly included the microwave discharge effect and the magnetic effect.In the sintering behavior,the material migration mode and the growth mechanism of sintering neck during the growing process were reviewed,the material migration mode was influenced by the material type and process parameter,and the growth of sintered neck was closely related to the temperature field and electromagnetic field.Based on the review of current research progress,the shortcomings and deficiencies were analyzed,and the future research direction of the microwave sintering mechanism was also proposed.
