Umsulwa wezentengiselwano nomaI-Alloy Nickel ephansiIthola uhlelo lwayo oluphambili ekusebenzeni kwamakhemikhali kanye ne-elekthronikhi.
Ukumelana nokugqwala
Ngenxa yokumelana nokugqwala kwe-nickel emsulwa, ikakhulukazi ukunciphisa amakhemikhali ahlukahlukene futhi ikakhulukazi ku-caustic alkalis, i-nickel isetshenziselwa ukugcina ikhwalithi yomkhiqizo ekuvuselweni okuningi kwamakhemikhali, ikakhulukazi ukucubungula kokudla kanye nokwenziwa kwe-fiber okwenziwe.
Izakhiwo ze-nickel emsulwa kwezentengiso
Uma kuqhathaniswaama-nickel alloys, I-Nickel Emsulwa Yezentengiselwano inokuqhutshwa okuphezulu kagesi, izinga lokushisa eliphakeme le-curie kanye nezindawo ezinhle zokuzikhulisa. I-nickel isetshenziselwa izintambo zokuhola ngogesi, izingxenye zebhethri, i-thyratrons kanye nama-electrodes.
I-nickel nayo inokuvuka okuhle okushisayo. Lokhu kusho ukuthi ingasetshenziselwa ukushintshaniswa kokushisa ezindaweni ezilonakalisayo.

Kuboniswa kwe-nickel
-Bothalekiwenickelunobulukhuni obuphansi ne-actility enhle. I-nickel, njengegolide, isiliva nethusi, inesilinganiso esiphansi somsebenzi, okusho ukuthi ayithathi hlangothi futhi i-brittle uma ihlala ikhubazekile noma ikhubazekile ngenye indlela njengezinye izinsimbi. Lezi zimfanelo, ezihlanganiswe nokufudumala okuhle, yenza i-metal ibe lula ukuba iwele ezintweni eziqediwe.
I-nickel e-chromium planing
I-nickel isetshenziswa kaningi njenge-undercoat ekuhlobiseni i-chromium plating. Umkhiqizo ovundwayo, onjengethusi noma i-zinc castring noma ukucindezela kwensimbi kuqala kufakwa kuqala ngesendlalelo senickelcishe ama-20μm aminyene. Lokhu kukunikeza ukumelana kwayo kokugqwala. Ijazi lokugcina liyi-'Flash 'elincanyana kakhulu (1-2μm) ye-chromium ukuyinika umbala nokumelana nethebula okuvame ukubhekwa njengokufiseleka ngokwengeziwe ku-ware enemibala. I-Chromium iyodwa ingaba nokumelana nokugqwayiza okungamukeleki ngenxa yemvelo evamile ye-chromium electromium electromium.

I-nickel efomini eliyisisekelo noma elihlanganiswe nezinye izinsimbi nezinto zokwakha zenze iminikelo ebalulekile emphakathini wethu wanamuhla futhi izethembiso zokuqhubeka nokunikeza izinto zekusasa elifunwa kakhulu. I-nickel ibilokhu iyinsimbi ebalulekile yezinhlobonhlobo zezimboni zesizathu esilula sokuthi iyisizathu esiguquguqukayo esizosebenza nezinye izinsimbi eziningi.
I-Nickel yinto eguquguqukayo futhi izokwazi izinsimbi eziningi. Ama-nickel alloys angama-alloy ane-nickel njengento eyinhloko. I-solubelity ephelele eqinile ikhona phakathi kwe-nickel nethusi. I-solubility ebanzi phakathi kwensimbi, i-chromium, ne-nickel yenza ukuhlanganiswa okuningi kwe-alloy. Ukuguquguquka okuphezulu kwayo okuphezulu, kuhlangene nokuvikelwa kwayo okuvelele nokugqwala kuholele ekusetshenzisweni kwayo ezinhlotsheni ezahlukahlukene zezicelo; Enjenge-turbines yegesi yendiza, i-turbines ye-steam ezitshalweni zamandla nokusetshenziswa kwayo okubanzi kumakethe yamandla enuzi.
