Nkọwa dị mkpirikpi:
Igwe ndọta Magnet nke oghere aluminom kpuchie, nke Hang Zhou Magnet Power mere ma rụpụta ya, na-enye ike na ịdịte aka 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. Otú ọ dị, nguzogide corrosion na-adịghị mma nke magnet na-egbochi iji ha eme ihe na ngwa azụmahịa, na 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.

Ịgbasa bụ ihe na-eme site n'iji ụmụ irighiri ihe dị elu na-atụ bọmbụ n'elu elu siri ike, na-eme ka atom na ụmụ irighiri ihe dị n'elu ahụ siri ike na-agbanwe ike nke kinetic na ihe ndị a nwere ike dị elu, si otú ahụ na-esi na elu ahụ pụta. Grove chọtara ya nke mbụ na 1852. Dị ka oge mmepe ya si dị, e nweela sputtering nke abụọ, sputtering nke atọ, na ihe ndị ọzọ. Otú ọ dị, n'ihi arụmọrụ dị ala na ihe ndị ọzọ, a naghị eji ya eme ihe ruo n'afọ 1974 mgbe Chapin mepụtara magnetron sputtering ziri ezi, na-eme ka ọsịsọ ọsọ na nke dị ala na-agbapụta eziokwu, na nkà na ụzụ magnetron sputtering nwere ike ịmalite ngwa ngwa. Ịgbasa Magnetron bụ usoro ịgbasa nke na-ewebata oghere electromagnetic n'oge usoro ịgbasa iji mee ka ọnụọgụ ionization dịkwuo 5% -6%. E gosipụtara eserese schematic nke nshịkọ magnetron ziri ezi na foto 1.

N'ihi na ya magburu onwe corrosion eguzogide, Al mkpuchi echekwara 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 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 5, nhazi nke akụkụ nke Al / Al2O3 multilayer mkpuchi.

Ugbu a, nsogbu ndị bụ isi na-egbochi mmepụta nke mkpuchi Al na NdFeB bụ:
(1) A na-edobe akụkụ isii nke magnet n'otu n'otu. Ihe a chọrọ maka nchebe magnet bụ itinye ihe mkpuchi kwekọrọ na elu elu nke magnet, nke na-achọ idozi ntụgharị akụkụ atọ nke magnet na nhazi nhazi iji hụ na nkwekọ nke mkpuchi dị mma;
(2) Usoro iwepụ mkpuchi mkpuchi. N'ime nnukwu mmepụta mmepụta ihe, ọ bụ ihe a na-apụghị izere ezere na ngwaahịa ndị na-erughị eru ga-apụta. Ya mere, ọ dị mkpa iji wepụ ihe mkpuchi Al na-erughị eru ma chekwa ya na-emebighị arụmọrụ nke NdFeB magnet;
(3) Dabere na gburugburu ngwa ngwa a kapịrị ọnụ, magnetik NdFeB nwere ọtụtụ akara ule na ụdị. Ya mere, ọ dị mkpa iji mụọ ụzọ nchebe kwesịrị ekwesị maka ọkwa dị iche iche na ụdị;
