Mbiri

Zamalonda zoyera kapenanickel low alloyimapeza ntchito yake yayikulu pakukonza mankhwala ndi zamagetsi.

Kukaniza kwa Corrosion

Chifukwa cha kukana kwa dzimbiri kwa nickel, makamaka kuzinthu zochepetsera zosiyanasiyana komanso makamaka ku caustic alkalis, faifi tambala amagwiritsidwa ntchito kuti zinthu zizikhala bwino pamachitidwe ambiri amankhwala, makamaka pokonza zakudya ndi kupanga ulusi wopangira.

Katundu wa Nickel Wopanda Malonda

Kuyelekeza ndinickel aloyi, faifi tambala yamalonda imakhala ndi mphamvu zamagetsi zapamwamba, kutentha kwa Curie komanso katundu wabwino wa magnetostrictive. Nickel imagwiritsidwa ntchito pamawaya otsogolera amagetsi, zida za batri, ma thyratron ndi ma elekitirodi oyaka.

Nickel imakhalanso ndi matenthedwe abwino. Izi zikutanthauza kuti zitha kugwiritsidwa ntchito posinthanitsa kutentha m'malo owononga.

Kupanga Nickel

Annealednickelali otsika kuuma ndi ductility zabwino. Nickel, monga golidi, siliva ndi mkuwa, imakhala ndi ntchito yochepa kwambiri youmitsa ntchito, mwachitsanzo, simakonda kukhala olimba komanso ophwanyika pamene ipindika kapena kupunduka monga momwe zimachitira zitsulo zina zambiri. Makhalidwe amenewa, kuphatikizapo weldability wabwino, zimapangitsa chitsulo kukhala chosavuta kupanga zinthu zomalizidwa.

Nickel mu Chromium Plating

Nickel imagwiritsidwanso ntchito nthawi zambiri ngati chovala chamkati pokongoletsa chromium plating. Chopangiracho, monga mkuwa kapena zinc kuponyera kapena chitsulo chosindikizira chimayamba kukutidwa ndi wosanjikiza wanickelpafupifupi 20µm wandiweyani. Izi zimamupatsa kukana kwa dzimbiri. Chovala chomaliza ndi 'flash' yopyapyala kwambiri (1-2µm) ya chromium kuti ipangitse mtundu komanso kukana koyipa komwe kumawonedwa ngati kofunikira kwambiri muzinthu zopukutidwa. Chromium yokhayo ingakhale ndi kukana kwa dzimbiri kosavomerezeka chifukwa chokhala ndi porous chromium electroplate.

Nickel mu mawonekedwe oyambira kapena ophatikizana ndi zitsulo ndi zida zina athandizira kwambiri anthu amasiku ano ndipo akulonjeza kuti apitiliza kupereka zida zamtsogolo zovuta kwambiri. Nickel yakhala chitsulo chofunikira kwambiri m'mafakitale osiyanasiyana chifukwa chosavuta kuti ndizinthu zosunthika kwambiri zomwe zimalumikizana ndi zitsulo zina zambiri.

Nickel ndi chinthu chosunthika ndipo amalumikizana ndi zitsulo zambiri. Ma aloyi a nickel ndi ma aloyi okhala ndi faifi tambala ngati chinthu chofunikira kwambiri. Kusungunuka kolimba kumakhalapo pakati pa faifi tambala ndi mkuwa. Kusungunuka kwakukulu pakati pa chitsulo, chromium, ndi faifi tambala kumapangitsa kuti aloyi ambiri azitha kuphatikiza. Kusinthasintha kwake kwakukulu, kuphatikizidwa ndi kutentha kwake kwakukulu ndi kukana kwa dzimbiri kwachititsa kuti agwiritsidwe ntchito m'njira zosiyanasiyana; monga ma turbines agasi a Ndege, makina opangira magetsi m'mafakitale opangira magetsi komanso kugwiritsa ntchito kwake kwambiri pamsika wamagetsi ndi nyukiliya.

Ntchito ndi Makhalidwe a Nickel Alloys

Nickel ndi nickel alloysamagwiritsidwa ntchito zosiyanasiyana, zambiri zomwe zimaphatikizapo kukana dzimbiri ndi/kapena kukana kutentha. Zina mwa izi ndi:

• Makina opangira gasi a ndege
• Malo opangira magetsi opangira nthunzi
• Mapulogalamu azachipatala
• Mphamvu za nyukiliya
• Makampani a Chemical ndi petrochemical
• Kutentha ndi Kukaniza mbali
• Ma Isolators ndi Actuators kuti athe kulumikizana
• Mapulagi a Automotive Spark
• Zowotcherera zogwiritsidwa ntchito
• Zingwe Zamagetsi

Ena angapomapulogalamu a nickel alloyskuphatikizira mawonekedwe apadera amtundu wa nickel-based or high-nickel alloys. Izi zikuphatikizapo:

• Zosakaniza zamagetsi
• Nickel-Chromium aloyindiNickel-Chromium-Iron alloys
• Zosakaniza za Copper-Nickelzowotchera zingwe
• Thermocouple Aloyikwa masensa ndi zingwe
• Mafuta a Nickel Copperkwa Kuluka-Kuluka
• Zofewa za maginito
• Ma aloyi owongolera-kukula
• Zida Zopangira Welding
• Dumet wayakwa Glass kuti asindikize zitsulo
• Chitsulo cha Nickel
• Magetsi Aloyi
