無損檢測.滲透法檢驗和磁粉檢驗.觀察條件The main reason are as following : on one hand, the nd - rich phases in the hydrogen desorpted powders is so brittle that they are easily milled too fine and some are run off seriously, and then inducing low density. on the other hand, the alignment of the magnets prepared by hydrogen desorption are much low. so the hydrogen desorption process should be modified, and the solution methods can be the substitution of traditional ingots with strip cast, the enhancement of the alignment magnetic field and the addition of nd - rich phase or ( and ) lubricant before the press
主要原因是hd磁粉中的富釹相較脆，在球磨時容易被磨成超細粉而造成過量流失和使磁體燒結不夠緻密；另外一個原因是hd法燒結磁體的易磁化軸的取向度較低，為了提高hd磁體的b _ r和（ bh ） _ （ max ）可對hd工藝進行改進，改進的方法可以是用鑄片代替鑄錠，提高成型磁場強度以及在磁粉成型前加富釹相和潤滑劑。Eddy - current sensor test technology is a kind of very popular untouched nondestructive test technology developed in last decades, which makes up five major modern nondestructive test technologies together with magnetic particle test, radial test, ultrasonic test and osmosis test
