【Abstract】 This article introduced the experimental process to develop the FeCo-Nd-B permanent magnet material in the way of the liquid impact compaction.The relations of real density with the spray noxxle and deposit centerave developed.The heat treatment on the properties has the obvious influence to the coercive force of this permanent-magnet material.This experiment obtains the firm bulk product with low oxide compound content and good homogeneous permanent magnetism characteristic.更多还原
