Izinto ze-NiCr, ezifushanisiwe ze-nickel-chromium alloy, ziyinto eguquguqukayo futhi esebenza kahle kakhulu egujwa ngenhlanganisela yayo eyingqayizivele yokumelana nokushisa, ukumelana nokugqwala, kanye nokuhamba kukagesi. Yakhiwe ngokuyinhloko i-nickel (imvamisa engu-60-80%) kanye ne-chromium (10-30%), enezici ezifana nensimbi, i-silicon, noma i-manganese ukuze kuthuthukiswe izici ezithile,Ama-alloys e-NiCrsezibaluleke kakhulu ezimbonini kusukela emkhathini kuya kwezikagesi—futhi imikhiqizo yethu ye-NiCr yakhelwe ukuthuthukisa lawa mandla ngokugcwele.

Ingqikithi yesikhalazo se-NiCr ukuzinza kwayo okuvelele kwezinga lokushisa eliphezulu. Ngokungafani nezinsimbi eziningi ezithambisayo noma ezikhipha i-oxidize lapho zichayeke ekushiseni okukhulu, ama-alloy e-NiCr agcina amandla awo emishini nobuqotho besakhiwo ngisho nasezingeni lokushisa elingaphezu kuka-1,000°C. Lokhu kungenxa yokuqukethwe kwe-chromium, okwenza ungqimba oluminyene, oluvikelayo lwe-oxide ebusweni, luvimbele ukuqhubekela phambili kwe-oxidation kanye nokuwohloka. Lokhu kwenza i-NiCr ilungele izinhlelo zokusebenza ezifana nezinto zokushisisa isithando somlilo, izingxenye zenjini yejethi, namakhilni ezimboni, lapho ukuchayeka okuqhubekayo ekushiseni okuphezulu kungenakugwenywa.

Ukumelana nokugqwala kungenye imfanelo ebalulekile. Ama-alloys e-NiCr ahamba phambili ekumelana nokuhlaselwa okuvela ezindaweni ezikhipha i-oxidizing, okuhlanganisa umoya, isitimu, namakhemikhali athile. Lesi sakhiwo sibenza babe yigugu ezimbonini zokucubungula amakhemikhali, lapho asetshenziswa khona kuma-heaters, ama-reactors, namasistimu amapayipi aphatha imidiya eqala ukugqwala. Ngokungafani nezinsimbi ezihlanzekile noma ama-alloys aqinile kancane, izinto ze-NiCr ziyamelana nokufaka umgodi, ukukala, nokugqwala, okuqinisekisa ukwethembeka kwesikhathi eside kanye nokunciphisa izindleko zokulungisa.

I-conductivity kagesi iyisici sesithathu esibalulekile. Nakuba ingaqhubeki njengethusi elimsulwa, ama-alloys e-NiCr anikeza ibhalansi eyingqayizivele ye-conductivity nokumelana nokushisa, okuwenza afanelekele izinto zokushisisa ezintweni zikagesi, izifudumezi zezimboni, nezimbangi zikagesi. Ikhono labo lokukhiqiza nokusabalalisa ukushisa ngokulinganayo ngaphandle kokwehlisa isithunzi liqinisekisa ukusebenza okungaguquki kumadivayisi afana namathosta, okomisa izinwele, namahhavini ezimboni.

Imikhiqizo yethu ye-NiCr yakhelwe ukukhulisa lezi zinzuzo. Sinikeza ukwakheka okuhlukahlukene, kusukela kuma-alloys ane-nickel ephezulu ukumelana nokushisa okwedlulele kuya kokuhlukile okucebile nge-chromium okulungiselelwe ukuvikela ukugqwala. Itholakala ngamafomu afana nezintambo, amaribhoni, amashidi, nezingxenye zangokwezifiso, imikhiqizo yethu yenziwe ngokunemba kusetshenziswa amasu athuthukile ukuze kuqinisekiswe ukwakheka okufanayo nokunemba kobukhulu. Ukuhlolwa kwekhwalithi okuqinile kuqinisekisa ukuthi ucezu ngalunye luhlangabezana nezindinganiso zomkhakha, kungakhathaliseki ukuthi ezezingxenye zebanga le-aerospace noma izinto zokushisisa zansuku zonke.

Ukuthi udinga into engakwazi ukumelana nobunzima bezinqubo zezimboni ezisezingeni eliphezulu noma imelane nokugqwala ezindaweni zamakhemikhali ezinokhahlo,imikhiqizo yethu ye-NiCrukuletha ukusebenza nokuqina ongakwethemba. Ngezixazululo eziklanyelwe izinhlelo zokusebenza ezihlukahlukene, sizimisele ukuhlinzeka ngezinto ze-NiCr eziphakamisa ukusebenza kahle nokuphila isikhathi eside kwamaphrojekthi akho.
