Nickel Chrome Resistance Alloys
Nichrome, yomwe imadziwikanso kuti nickel chrome, ndi aloyi wopangidwa ndi kusakaniza faifi tambala, chromium ndipo, nthawi zina, chitsulo. Chodziwika kwambiri chifukwa cha kukana kutentha, komanso kukana kwake ku dzimbiri ndi makutidwe ndi okosijeni, alloy ndi yothandiza kwambiri pamagwiritsidwe angapo. Kuchokera pakupanga mafakitale kupita ku ntchito yosangalatsa, nichrome mu mawonekedwe a waya imapezeka muzamalonda, zaluso ndi zida. Imapezanso mapulogalamu m'makonzedwe apadera.
Waya wa Nichrome ndi aloyi wopangidwa kuchokera ku nickel ndi chromium. Imakana kutentha ndi okosijeni ndipo imakhala ngati chinthu chotenthetsera pazinthu monga toasters ndi zowumitsa tsitsi. Hobbyists amagwiritsa ntchito waya wa nichrome muzojambula za ceramic ndi kupanga magalasi. Waya amathanso kupezeka m'ma laboratories, zomangamanga ndi zamagetsi zapadera.
Chifukwa waya wa nichrome ndi wosagwirizana ndi magetsi, ndiwothandiza kwambiri ngati chinthu chotenthetsera pazinthu zamalonda ndi zida zapakhomo. Ma toaster ndi zowumitsira tsitsi amagwiritsa ntchito waya wa nichrome kupanga kutentha kwakukulu, monganso mavuni opangira toaster ndi zotenthetsera zosungirako. Ng'anjo za mafakitale zimagwiritsanso ntchito waya wa nichrome kuti agwire ntchito. Utali wa waya wa nichrome ungagwiritsidwenso ntchito popanga chodulira waya wotentha, womwe ungagwiritsidwe ntchito kunyumba kapena m'mafakitale kuti udule ndi kuumba thovu ndi mapulasitiki.
Waya wa Nichrome amapangidwa ndi aloyi wopanda maginito wopangidwa makamaka ndi faifi tambala, chromium, ndi chitsulo. Nichrome imadziwika ndi kukana kwake kwakukulu komanso kukana kwa okosijeni. Waya wa Nichrome ulinso ndi ductility wabwino pambuyo pa kugwiritsidwa ntchito komanso kuwotcherera kwambiri.
Nambala yomwe imabwera pambuyo pa mtundu wa waya wa Nichrome ikuwonetsa kuchuluka kwa nickel mu alloy. Mwachitsanzo, "Nichrome 60" ali pafupifupi 60% Nickel zikuchokera.
Kugwiritsa ntchito waya wa Nichrome kumaphatikizapo zinthu zotenthetsera zowumitsa tsitsi, zosindikizira kutentha, ndi chithandizo cha ceramic mu ng'anjo.
