Pakutsvaga chekutsivanichrome waya, zvakakosha kuti titarise zvakakosha zvivakwa zvinoita kuti nichrome ive yakakosha: yakakwirira-tembiricha kuramba, inopindirana yemagetsi resistivity, corrosion resistance, uye durability. Nepo zvinhu zvakati wandei zvichiuya pedyo, hapana chinofananidzira nichrome yakasarudzika chiyero chekuita-ichiita yedu nichrome waya zvigadzirwa sarudzo yakavimbika yeakakosha maapplication.
Imwe nzira yakajairika ndeye kanthal waya, aniron-chromium-aluminium alloy. Kanthal inokunda munzvimbo dzine tembiricha yepamusoro, inoshingirira tembiricha inosvika 1,400 ° C, iyo yakakwirira kudarika mamwe magiredhi enichrome. Zvisinei, ine brittle uye hainyanyi kuumbika, zvichiita kuti zviome kuigadzira kuva madhizaini akaomarara. Mumaapplication anoda kuchinjika, senge madiki ekudziya zvinhu mumagetsi, kanthal kazhinji inodonha, nepo nichrome's ductility inobvumira kuumbwa chaiko pasina kutsemuka.
Mhangura-nickel (Cu-Ni) waya imwe inokwikwidza, inokosheswa nekushongedzwa kwayo kwekuora uye ine mwero resistivity. Asi Cu-Ni inonetseka nekupisa kwakanyanya, ichiita oxidizing nekukurumidza pamusoro pe300 ° C, iyo inodzikamisa kushandiswa kwayo munzvimbo dzinopisa zvakanyanya senge vira remaindasitiri kana kupisa makoiri. Nichrome, nekusiyana, inochengetedza kugadzikana kunyange pa1,200 ° C, zvichiita kuti iwedzere kushandiswa kwemabasa ekupisa kwepamusoro.
Tungsten waya inopa kusarudzika kupisa kupisa, kushingirira tembiricha yakanyanyisa kusvika 3,422 ° C. Nekudaro, ine brittle zvakanyanya uye ine yakaderera magetsi resistivity, inoda mamhepo epamusoro kuti agadzire kupisa. Izvi zvinoita kuti zvisashande kune akawanda ekudziya maapplication uko simba rekushandisa uye nyore kushandisa zvinhu-nzvimbo uko nichrome, ine kwakaringana resistivity uye kushanda, inopenya.
Stainless simbi waya inowanzotaridzirwa nekuda kwekugona kwayo uye kusagadzikana kwemarara. Asi, ine yakaderera resistivity pane nichrome, zvichireva kuti inogadzira kupisa kushoma pakureba kweyuniti, inoda mageji akakora kana mavoltages akakwira kuti aenderane nekubuda kwenichrome. Nekufamba kwenguva, simbi isina simbi zvakare inozokanganisa mukupisa kwenguva refu, ichideredza hupenyu hwayo kana ichienzaniswa nekugadzikana kwenguva refu kwenichrome.
Yedu nichrome waya zvigadzirwa zvinogadzirisa izvi zvipimo zvezvinotsiva. Inowanikwa mumagiredhi akasiyana (sengeNiCr 80/20), vanopa chaiyo resistivity yekuenderana kupisa kubuda, yakanakisa ductility kugadzirwa nyore, uye yepamusoro oxidation kuramba pakupisa kwakanyanya. Ingave yekudziya zvinhu mumidziyo, midziyo yemurabhoritari, kana mavira indasitiri, waya yedu yenichrome inopa kuita kwakavimbika, kushanda nesimba, uye kusimba izvo dzimwe nzira dzinonetsa kutevedzera.
Kusarudza waya chaiyo kunoreva kuisa pamberi iyo yakasarudzika musanganiswa wezvivakwa izvo chete nichrome inopa. Zvigadzirwa zvedu zvakagadziridzwa kuti zvisangane nekusimba kwemhando zviyero, kuve nechokwadi kuti zvinodarika zvinotsiva mune zvese kushanda uye hupenyu hurefu-zvichiita ivo sarudzo yakangwara yezvido zvako zvekudziya.
