Nickel Chromium NiCr Alloy
Lisebelisoa tsa nickel-chromium li sebelisoa haholo libōping tsa motlakase tsa indasteri, lisebelisoa tsa ntlo, lisebelisoa tse hōle tsa infrared le lisebelisoa tse ling ka lebaka la matla a tsona a phahameng a mocheso le polasetiki e matla. Nickel-chromium le tšepe, aluminium, silicon, k'habone, sebabole le lintho tse ling li ka etsoa terata ea alloy ea nickel-chromium, e nang le matla a phahameng a ho hanyetsa le ho hanyetsa mocheso 'me ke karolo ea mocheso oa motlakase oa sebōpi sa motlakase, tšepe ea tšepe ea motlakase, tšepe ea motlakase le tšepe. lihlahisoa tse ling.
Ntle le moo, terata ea NiCr hangata e sebelisoa ho coil ea rheostat e thellang ho sireletsa potoloho le ho fetola sejoale-joale potolohong ka ho fetola khanyetso ea karolo ea potoloho ea phihlello, ka hona ho fetola motlakase ho pholletsa le conductor (sesebelisoa sa motlakase) se hokahantsoeng letotong le. eona, E sebelisoa haholo ka palo e kholo ea lisebelisoa tsa ntlo.
NiCr Alloy Series
Ni90Cr10 strip ke mofuta oa lihlahisoa tsa alloy ea nickel-chromium, e loketse lisebelisoa tsa mocheso ho fihlela ho 1250 ° C. Litaba tsa Chromium li fana ka nako e ntle ea bophelo, hangata e sebelisoa e le ntho ea ho futhumatsa vape.
Ni90Cr10 e tšoauoa ka resistivity e phahameng, khanyetso e ntle ea oxidation, ductility e ntle ka mor'a ts'ebeliso le ts'ebetso e ntle haholo ea weldability. NiCr Alloy ke thepa e ntle bakeng sa indasteri ea ho futhumatsa.
