Ukuqulunqwa kokudluliselwa kwentsimbi kunye nobungqingqwa befilimu yokuphumelela

Ukudluliselwa kuchazwa njengokuqulunqwa komkhenkce ophantsi kakhulu kumphezulu wezinto zentsimbi phantsi kweemeko ze-oxidic, ezifezekisiweyo ngokubekwa kwe-onodic eqinileyo, ukuthintela ukungangqinelani. Ezinye izinyithi okanye i-alloys iphuhlise i-inhibing encancisayo kwindawo yokusebenza okanye phantsi kophawu olunobuthathaka, ngaloo ndlela kuncitshiswa ireferensi. Ngokwenkcazo yokudluliselwa kwempahla, le meko ayithathi ntweni.

Ubume befilimu ye-plastivation bunqabile kakhulu, inomlinganiselo wobunzima obususela kwi-1 ukuya kwi-10 i-10anometers. Ukufumanisa i-hydrogen kwifilimu enamadlelane ibonisa ukuba ifilimu yokupasa inokuba yi-hydroxide okanye i-hydrate. Intsimbi (Fe) kunzima ukwenza ifilimu yokwahlulwa phantsi kweemeko eziqhelekileyo zokulima; Kwenzeka kuphela kwiindawo zokungena ze-oxididing kwaye kwaye phantsi kophawu olungcolileyo kwizinto eziphezulu. Ngokwahlukileyo, iChromium (CR) inokwenza isitali esizinzileyo, esimdaka, kunye ne-filivations ekhuselekileyo kwimo engqonge i-oxiding. Kwizabelo ezisekwe ngentsimbi equkethe i-chromium, xa umxholo weChromium ungaphezulu kwe-12%, ibizwa ngokuba yintsimbi engenasiseko. Intsimbi engenanto inokugcina imeko edluliselweyo kwizisombululo ze-accought ezininzi ezinamaxabiso omoya. I-nickel (Ni), xa kuthelekiswa nentsimbi, ingekuphela nje kwe-iron ye-Points (kubandakanya amashishini angcono (kubandakanya amandla aphezulu amaqondo obushushu) kodwa ikwabonisa ukunganyangeki kwe-corosion ngokuzenzekelayo kuzo zombini ukungazithembi

I-Nickel (NI), xa kuthelekiswa nentsimbi, ingeyi kuphela iipropathi ezingcono zoomatshini (kubandakanya iindawo eziphezulu zobushushu) kodwa zibonisa imeko yokunyanzela okungafihlisiyo kunye ne-oxiding. Xa i-nickel yomxholo idlula i-8%, ikwazisa ubuso obugxile kubuso bobuso bokwazisa, ukuphucula ukhuseleko lokukhusela kunye nokuphucula ukukhuselwa kwesiko. Ke ngoko, iChromium kunye ne-chprel ibaluleke kakhulu kwizinto zentsimbi.
