Nkọwa dị mkpirikpi:
Igwe ndọta aluminom na-adịghị ahụkebe, nke Hang Zhou Magnet Power mere ma rụpụta ya, na-enye ike na ogologo oge dị egwu.Ihe owuwu ya pụrụ iche na-eme ka o doo anya na ọ nwere ike iguzogide ọbụna ọnọdụ ndị na-achọsi ike, na-eme ka ọ bụrụ ngwọta dị mma maka ọtụtụ ụlọ ọrụ mmepụta ihe na azụmahịa.
●Ihe ndọta nke NdFeBejirila ya mee ihe n'ọtụtụ ebe maka njirimara magnetik ha dị ịrịba ama.Agbanyeghị, nguzogide corrosion na-adịghị mma nke magnet na-egbochi iji ha ọzọ na ngwa azụmahịa, yana mkpuchi elu dị mkpa.Ihe mkpuchi a na-ejikarị eme ihe ugbu a na-agụnye mkpuchi Ni-based electroplating, electroplating Zn dabeere na mkpuchi, yana electrophoretic ma ọ bụ ịgbasa mkpuchi epoxy.Ma na ọganihu na-aga n'ihu nke nkà na ụzụ, ihe ndị a chọrọ maka mkpuchi nke NdFeB na-arịwanye elu, na oyi akwa electroplating mgbe ụfọdụ enweghị ike izute ihe ndị a chọrọ.Ihe mkpuchi nke Al nke etinyebere site na iji teknụzụ vepor deposition (PVD) nwere njirimara mara mma.
● Usoro PVD dị ka sputtering, ion plating, na evaporation plating nwere ike nweta mkpuchi nchebe.Isiokwu 1 depụtara ụkpụrụ na njirimara atụnyere nke electroplating na sputtering ụzọ.

N'ihi na ya magburu onwe corrosion eguzogide, Al mkpuchi echekwabara site ion vapor deposition (IVD) e ji mee ihe site Boeing dị ka ihe nnọchi maka electroplating Cd.Mgbe ejiri ya maka sintered NdFeB, ọ na-enwekarị uru ndị a:
1.High ike nrapado.
Ike nrapado nke Al naNdFeBbụ n'ozuzu ≥ 25MPa, mgbe nrapado ike nke nkịtị electroplated Ni na NdFeB bụ banyere 8-12MPa, na nrapado ike nke electroplated Zn na NdFeB bụ banyere 6-10MPa.Njirimara a na-eme Al/NdFeB dabara maka ngwa ọ bụla chọrọ ike nrapado dị elu.Dị ka e gosiri na Figure 2, mgbe a gbanwere 10 cycles nke mmetụta n'etiti (-196 ° C) na (200 Celsius C), nrapado ike nke Al mkpuchi na-anọgide magburu onwe ya.

3.The magnetik permeability nke Al dị nnọọ ala ( ikwu permeability: 1.00) na-agaghị eme ka ikpuchi nke magnetik Njirimara.
Nke a dị mkpa karịsịa na ntinye obere magnetik olu na mpaghara 3C.Ịrụ ọrụ elu dị ezigbo mkpa.Dị ka egosiri na eserese 4, maka kọlụm nlele D10 * 10, mmetụta nke mkpuchi Al na ihe ndọta dị ntakịrị.
Ọgụgụ 4 Mgbanwe na njirimara magnetik nke sintered NdFeB mgbe etinyere mkpuchi PVD Al na mkpuchi NiCuNi electroplating n'elu.
5.The PVD technology deposition usoro bụ kpamkpam gburugburu ebe obibi enyi na enyi na ọ dịghị nsogbu mmetọ gburugburu ebe obibi.
Dị ka ihe dị mkpa chọrọ, teknụzụ PVD nwekwara ike idobe multilayers, dị ka Al / Al2O3 multilayers nwere ezigbo nguzogide corrosion na mkpuchi Al / AlN nwere ezigbo ihe eji arụ ọrụ.Dị ka egosiri na eserese 6, nhazi nke akụkụ nke Al / Al2O3 multilayer mkpuchi.
