Abstract

When choosing technological modes of diffusion welding of iron with metals it is necessary to consider that during heating of ferrite materials in a vacuum there is a possibility of changes in the structure and the main electromagnetic parameters of the ferrites. Given the large diversity of physical and chemical properties of the ferrite materials, it is necessary to assess the impact of vacuum-thermal effects on the parameters of virtually every type of ferrites, which will determine the future fabrication technology territorialistic nodes. Studies have shown that the heating of ferrite materials in a vacuum affects their resistivity, this is due to the oxygen loss ferrite material, but when you are heating up in the air ferrite materials to restore the conductivity that is due to the return of oxygen in the structure of ferrite. The analysis of the dependence of the strength of connections territorialistic nodes from selecting a temperature, welding pressure and time of isothermal aging, allows to choose optimum modes of welding.

电子设备用铁金属焊缝形成的工艺特点

在选择铁与金属扩散焊接工艺模式时，必须考虑到铁氧体材料在真空加热过程中，铁氧体的结构和主要电磁参数可能发生变化。考虑到铁氧体材料的物理和化学性质的多样性，有必要评估真空热效应对几乎所有类型铁氧体参数的影响，这将决定未来制造技术的领域节点。研究表明，铁氧体材料在真空中加热会影响它们的电阻率，这是由于铁氧体材料的氧损失造成的，但是当你在空气中加热铁氧体材料恢复导电性那是由于铁氧体结构中氧的返回。分析了连接区域节点强度与温度、焊接压力和等温时效时间的关系，从而选择了最佳的焊接方式。
