Kusanganisa mhangura uye nickel kunogadzira mhuri yealloys inozivikanwa semhangura-nickel (Cu-Ni) alloys, iyo inosanganisa zvakanakisa zvivakwa zvesimbi mbiri kugadzira chinhu chine hunhu hunoshamisa hwekuita. Iyi fusion inoshandura hunhu hwavo hwega kuita synergistic seti yemabhenefiti, kugadziraCu-Ni alloysyakakosha mumashandisirwo akasiyana siyana emaindasitiri-uye zvigadzirwa zvedu zveCu-Ni zvakagadzirirwa kuwedzera mabhenefiti aya.
Pachiyero chemolecular, mhangura uye nickel zvinoumba mhinduro yakasimba kana yasanganiswa, zvichireva kuti maatomu emasimbi ese ari maviri anogovera zvakafanana mukati mezvinhu zvese. Kufanana uku ndiko kunokosha kune yavo yakagadziridzwa zvinhu. Mhangura yakachena inobatika zvakanyanya uye inoumbika asi haina corrosion resistance, ukuwo nickel yakasimba uye isingaite ngura asi isingaite. Pamwe chete, vanogadzira chinhu chinoenzanisa hunhu uhu.
Chimwe chezvakakosha mhedzisiro yemusanganiswa uyu ndeyepamusoro corrosion resistance. Iyo nickel yemukati muCu-Ni alloys inoumba dense, inodzivirira oxide layer pamusoro, ichidzivirira zvinhu kubva mumvura yemunyu, asidhi, uye makemikari emumaindasitiri. Izvi zvinoita kuti maCu-Ni alloys ave akanakira nharaunda dzemugungwa, senge zvikepe zvengarava, pombi dzemvura yegungwa, uye mapuratifomu ekumahombekombe, uko mhangura yakachena yaikurumidza kuita ngura. Zvigadzirwa zvedu zveCu-Ni, zvakagadzirirwa zvigadziriso zvakaomarara izvi, kuramba gomba, kukoromoka, uye kukukurwa kwevhu, kuve nechokwadi chekugara kwenguva refu.
Mechanical simba zvakare rinowana kukwidziridzwa kubva kumhangura-nickel musanganiswa. Cu-Ni alloys yakasimba uye yakaoma kudarika mhangura yakachena, ichichengetedza ductility yakanaka. Izvi zvinovatendera kuti vamire kushushikana kwakanyanya kwemagetsi mumashandisirwo akaita sepombi, mavharuvhu, uye zvinopisa zvinopisa. Kusiyana nemhangura yakachena, iyo inogona kukanganisa pasi pemitoro inorema, yedu Cu-Ni waya uye mashizha anochengetedza kutendeseka kwechimiro kunyange mumamiriro ezvinhu akaoma, kuderedza zvido zvekugadzirisa.
Thermal uye magetsi conductivity inoramba ichinakidza muCu-Ni alloys, kunyange zvishoma zvishoma kudarika mhangura yakachena. Izvi zvinovaita kuti vakwanise kupisa zvinopisa uye zvikamu zvemagetsi uko kushorwa kwecorrosion kwakakosha sekuita. Semuyenzaniso, muzvinomera zvekubvisa salination, machubhu edu eCu-Ni anonyatso fambisa kupisa uku achiramba kuparara kwemvura yemunyu.
Zvigadzirwa zvedu zveCu-Ni zvinowanikwa mumhando dzakasiyana siyana, zvine nickel zvemukati kubva pa10% kusvika 30%,zvinoenderana nezvinodiwa zvekushandisa. Kunyangwe iwe uchida waya dzakatetepa dzezvikamu zvakaomarara kana mashiti akakora ezvimiro zvinorema-basa, yedu chaiyo kugadzira inovimbisa kuenderana uye kuita. Nekushandisa zvakasarudzika mabhenefiti emhangura-nickel musanganiswa, zvigadzirwa zvedu zvinoburitsa kuvimbika uye hupenyu hurefu munzvimbo umo simbi dzakachena dzinodonha.
