Kedu ihe e ji ekpuchi magnetik?

	A ghaghị ikpuchi magnetik ma ọ bụ na ha ga-emebi ngwa ngwa ma ọ bụrụ na emeghere ihe ndị ahụ. Ihe ndọta niile, ma e wezụga ihe ndọta weld, brushes magnetik, ndọta aka na ihe ndọta ndọta, enwere ike iji ihe dị iche iche kpuchie ya. Edepụtara ihe mkpuchi ndị kachasị ewu ewu n'okpuru:
nickel - ọla kọpa - nickel
	Nickel-ọla kọpa-nickel plating (nke a maara dị ka nickel plating) nwere akwa atọ dị iche iche: nickel, oyi akwa ọla kọpa, na oyi akwa nickel nke abụọ.
	Enwere ike ịse ụdị mkpuchi a n'elu, na-eme ka mkpuchi nickel-copper-nickel mara mma karịa ihe mkpuchi magnetik ndị ọzọ dị.
	A na-eji usoro agba agba mkpuchi a na magnets mmanya ebe ọ dị mkpa ka a na-ese ogwe ndọta dị iche iche na agba dị iche iche maka ebumnuche mmụta.
epoxy resin
	Epoxy bụ ụdị mkpuchi rọba na-eme ka nguzogide corrosion nke magnet dị mma. Ụdị mkpuchi a ga-adịru ogologo oge ma ọ bụrụ na emebighị ya, agbanyeghị, ọ na-akpụ akpụ ngwa ngwa na-eme ka ọ bụrụ otu n'ime ihe mkpuchi magnet na-adịgide adịgide.
Zinc
	Enwere ike iji zinc kpuchie diski magnetik, magnets mmanya na ihe ndọta inyinya, nke na-eme ka ihe ndọta ahụ na-eguzogide corrosion yana dịkwa ọnụ ala iji.
	Ihe mkpuchi zinc na-arụ ọrụ dị ka mkpuchi ịchụ aja maka magnet, nke pụtara na oyi akwa zinc na-agwụ tupu magnet corrodes. Zinc bụ ihe mgbochi sitere n'okike na mmiri, yabụ ọ bụrụ na mmiri abanyeghị na magnet, a gaghị enwe corrosion.
Polytetrafluoroethylene (PTFE)
	Polytetrafluoroethylene (PTFE), nke a makwaara dị ka mkpuchi Teflon, bụ ụdị ọzọ nke nchebe magnet. A na-eji mkpuchi PTFE mee ka nguzogide mmetụta dịkwuo mma ma kwe ka magnet abụọ ahụ dị iche iche dị mfe mgbe ejikọtara ya.
	Ihe mkpuchi PTFE bara uru karịsịa maka igosi otú magnet si arụ ọrụ na klas, dịka mkpuchi na-echebe magnet site na nkwụsịtụ, nke dị ize ndụ karịsịa mgbe ụmụaka na-egwu ha.
Gold
	Enwere ike iji ọla edo 22 carat kpuchie diski magnetik. A na-eji ihe ndọta mkpuchi mkpuchi mee ihe na ọgwụgwọ magnetik, ebe a kwenyere na magnet na-enyere aka ịgwọ ọtụtụ ọrịa dị iche iche.
	A na-eji ọla edo edo edo kpuchido akpụkpọ anụ ahụ site na ihe (dị ka neodymium) nke mejupụtara magnet. Ihe ndị dị na magnet nwere ike ime ka akpụkpọ anụ ahụ ma ọ bụrụ na ha na-ejikọta ya ruo ogologo oge.
Kedu mkpuchi ịhọrọ?
	Kedu mkpuchi ị na-ahọrọ ga-adabere n'ụzọ dị ukwuu n'ogo nke nguzogide corrosion chọrọ, n'ihi na nke a bụ isi ọrụ nke mkpuchi ahụ. Ihe mkpuchi na-enye ọkwa kachasị elu nke nguzogide corrosion bụ zinc. Ọ dịkwa ọnụ ala ma e jiri ya tụnyere mkpuchi ndị ọzọ, na-eme ka ọ bụrụ nhọrọ akụ na ụba.
