Since 2002 , focus on manufacturing and supplying various kinds of bonded ferrite magnets


The sintering technology of sintered ndfeb

by:Maghard      2020-09-19
Sintered sintered ndfeb refers to in order to further improve the performance and practicability of the magnets, improve the contact between the powder properties, increase strength, make the microstructure characteristics of magnets with high performance, need to heat the green powder matrix phase below the melting point temperature and holding time of the process. Sintering into liquid phase sintering and solid phase sintering, the two kinds of sintering method has much in common. In terms of sintering method, in addition to the traditional way of sintering, has gradually developed the following a few more new sintering techniques such as electric spark sintering, the discharge plasma sintering and microwave sintering rapid reaction sintering process and the electric field.
