Olu luhlu lukhethekileyo lwezinto lwenza ukuba i-Hastelloy imelane nobunzima, indalo engqongileyo edibana nayo kumashishini afana nokulungiswa kweekhemikhali, i-aerospace, ioli kunye negesi, kunye nokunye, ukuqinisekisa ixesha elide kunye nokuthembeka kwezixhobo ezibalulekileyo.
Indlela yokuNxhathisa iCorrosion
I-alloys ye-Hastelloy iyamelana nokubola ngenxa yomgaqo-siseko wayo kunye nezinto ezixutywayo. I-Hastelloy yenziwe ikakhulu nge-nickel, enenzuzo ekukhuseleni kwi-corrosion kuba ayisebenzi kwiindawo ezininzi ezinobungozi. I-alloying element engafanelekanga ukuba ingahoywa yichromium, enegalelo kwi-corrosion resistance ye-alloy ngokwenza i-passive oxide layer kumphezulu we-alloy.
I-molybdenum, ngakumbi ekuphuhliseni ezi ngxubevange, ibalulekile njengoko iphucula ukuxhathisa kwengxubevange kwiindidi ezininzi zomhlwa wendawo, kubandakanywa ukubola kwemingxuma kunye nemingxuma. Ikwaphucula ukusebenza kwengxubevange kwiimeko ezinzima, naxa ivezwe kwikloridi, iiasidi, kunye nezinye iindawo ezinobundlobongela. Isixa esikhulu se-molybdenum sixhathisa ukubola. Ke ngoko, ii-alloys zeHastelloy zinokusebenza phantsi kweemeko ezinzima kakhulu.
I-Tungsten yongezwa kwamanye amabakala e-Hastelloy ukunika i-oxidation engcono kunye nokuxhathisa ukubola kumaqondo obushushu aphezulu. I-Tungsten ikwanyusa ukumelana nohlaselo lwe-alloy intergranular, ukuyivumela ukuba isetyenziswe kwindawo enobutshaba kumaqondo obushushu aphezulu.
Ukwakhiwa kweekhemikhali okusebenzayo kwahlula i-alloys ye-Hastelloy ngenxa yokudityaniswa kwe-nickel, i-chromium, i-molybdenum, kwaye ngamanye amaxesha i-tungsten, ebanika ukuxhathisa ukubola. Iipropathi zayo ziyivumela ukuba ijongane nemekobume enobutshaba kunye neyonakalisa ekusetyenzweni kweekhemikhali, i-aerospace, kunye ne-oyile kunye negesi yegesi. Iimeko ezinjalo zinokuba nzima ukumelana, kodwa iindlela ze-corrosion ze-Hastelloy zivumela izixhobo ezibalulekileyo ukuba zisebenze ngokufanelekileyo kwaye zandise ubomi bayo benkonzo.
Ukuqonda iPitting kunye neCrevice Corrosion
I-Pitting kunye ne-crevice Corrosion ziindidi eziqhelekileyo zomhlwa kwendawo enokuthi ibangele imingeni ebalulekileyo kwimfezeko kunye nokuqina kwemathiriyeli, ngakumbi kwiindawo ezinobundlobongela. I-Pitting corrosion yenzeke xa iindawo ezincinci okanye imingxuma kumphezulu we-material iba lula kakhulu kwi-corrosion, ekhokelela ekwakhekeni kwemingxuma emincinci okanye imingxuma. I-Crevice corrosion, kwelinye icala, iyenzeka kwizithuba ezimxinwa okanye kwimingxuma apho izisombululo ze-electrolyte ezimileyo okanye ezibanjiweyo zinokuqokelelana, zidale imeko-bume ekhuthaza ukuhlwa.
