ezinengilazi ezikhethekile
Ngemva kweminyaka yocwaningo nokuthuthukiswa kwezimboni. I-Hangzhou Magnet Power Technology ikwazile ukuhlinzeka ngozibuthe abayinqwaba be-PVD Al kumakhasimende. I-Al coating efakwe i-ion vapor deposition (IVD) isetshenziswe i-Boeing esikhundleni se-electroplating Cd. Uma isetshenziselwa i-Sintered NdFeB, ngokuyinhloko inezinzuzo ezilandelayo: 1. Amandla aphezulu okunamathela. 2. Gcoba ku-glue. 3.Ukungena kazibuthe kwe-Al kuphansi kakhulu futhi ngeke kubangele ukuvikelwa kwezakhiwo kazibuthe. 4.Ukufana kokuqina kungcono kakhulu5.Inqubo yokubeka ubuchwepheshe be-PVD ihambisana ngokuphelele nemvelo futhi ayikho inkinga yokungcoliswa kwemvelo.
