Nickel Chrome Resistance Alloys
Nichrome, inozivikanwawo se nickel chrome, ialloy inogadzirwa nekusanganisa nickel, chromium uye, dzimwe nguva, iron. Inonyanya kuzivikanwa nekudzivirira kwayo kupisa, pamwe nekuramba kwayo kune zvese ngura uye oxidation, iyo alloy inobatsira zvinoshamisa kune akati wandei maapplication. Kubva pakugadzira maindasitiri kusvika kune basa rekuzvivaraidza, nichrome muchimiro chewaya iripo mune dzakasiyana siyana zvekutengesa zvigadzirwa, mhizha uye maturusi. Iyo zvakare inowana maapplication mune yakasarudzika marongero.
Nichrome waya ialloy yakagadzirwa kubva nickel uye chromium. Inopikisa kupisa uye oxidation uye inoshanda sechinhu chinopisa muzvigadzirwa zvakadai sema toasters uye vhudzi rebvudzi. Hobbyists vanoshandisa nichrome waya mune ceramic sculpture uye kugadzira magirazi. Iyo waya inogona zvakare kuwanikwa mumarabhoritari, kuvaka uye nyanzvi dzemagetsi.
Nekuti nichrome waya inopokana nemagetsi, inobatsira zvinoshamisa sechinhu chekudziya muzvigadzirwa zvekutengesa uye maturusi epamba. Toaster uye zvekuomesa bvudzi zvinoshandisa coils ye nichrome waya kugadzira huwandu hukuru hwekupisa, sezvinoita mahovhoni e toaster uye maheater ekuchengetera. Maindasitiri echoto anoshandisawo nichrome waya kuita basa. Hurefu hwewaya yenichrome hunogonawo kushandiswa kugadzira chinopisa waya chinocheka, chinogona kushandiswa kungave kumba kana munzvimbo yeindasitiri kucheka nekuumba mamwe mafuro nemapurasitiki.
Nichrome waya inogadzirwa neisiri-magnetic alloy inoumbwa kunyanya nickel, chromium, uye iron. Nichrome inoratidzirwa nekukwirira kwayo kwepamusoro uye yakanaka oxidation kuramba. Nichrome waya zvakare ine yakanaka ductility mushure mekushandisa uye yakanakisa weldability.
Nhamba inouya mushure memhando yewaya yeNichrome inoratidza chikamu chenickel mune alloy. Semuenzaniso, "Nichrome 60" ine 60% Nickel mukuumbwa kwayo.
Zvishandiso zveNichrome waya zvinosanganisira kudziyisa zvinhu zvemaomesa ebvudzi, zvisimbiso zvinopisa, uye tsigiro yeceramic mumoto.
