Abstract

The invention discloses a novel production process of neodymium iron boron, comprising the following steps: 1) inspection and analysis of raw material components; 2) compounding; 3) melting; 4) hydrogen crushing; 5) milling; 6) pressing; ) isostatic pressing; 8) sintering; 9) blank forming; 10) placement of the blank on the detector for detection; 11) conforming of grinding, slicing, and semi-finished inspection after inspection; 12) electroplating; 13) chamfering, degreasing, pickling, activation, ultrasonic cleaning, Ni pre-plating, Cu plating, and Ni lighting; 14) finished product inspection; and 15) package, storage and transportation. The invention improves the processing performance of the neodymium iron boron, and avoids the phenomenon of cornering and chipping.

Description

technical field [0001] The invention particularly relates to a novel production process of NdFeB. Background technique [0002] In the prior art, the processing performance of NdFeB after production and processing is generally poor. In the process of use, there are often corner drop, chipping, and even breakage. This will not only cause many defective products, but also delay a lot of construction time. , so that work efficiency cannot be improved. Contents of the invention [0003] In order to solve the problems existing in the above-mentioned background technology, the object of the present invention is to provide a novel NdFeB production process, so as to achieve the purpose of improving the processing performance of NdFeB and avoiding corner drop and edge chipping. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A novel production process of neodymium iron boron, comprising the following steps: [0006] 1) ...
