Corrosion na-eguzogide alloys n'ozuzu enweghị ike iji na corrosive gburugburu na ike reducibility ma ọ bụ elu sealing arụmọrụ (anoxic gburugburu ebe obibi), na arụmọrụ nke ngwaahịa na-mgbe niile na-emelite, na ha na-ọtụtụ ebe, na e nwere ọtụtụ ndị na-emepụta ngwaahịa, otú e si eme ya. họrọ Onye nrụpụta dabara gị mma bụ sayensị.N'otu aka ahụ, ekwesịrị ịtụle ihe ọmụma n'ihe gbasara ọnụahịa, yana akụkụ ndị ọzọ kwesịkwara ịtụle n'ụzọ zuru ezu, dị ka ma a na-ahazi onye nrụpụta yana ma ọ ga-ekwe nkwa ọrụ ire ere.
Alloy na-eguzogide corrosion
Kedu ụdị alloys na-eguzogide corrosion?
1. Corrosion nke igwe anaghị agba nchara
Tumadi na-ezo aka nkịtị 300 usoro igwe anaghị agba nchara 304, 316L, 317L, wdg na-eguzogide ikuku ma ọ bụ oké osimiri corrosion;austenitic igwe anaghị agba nchara 904L, 254SMO na ike corrosion eguzogide;duplex ígwè 2205, 2507, wdg;alloys na-eguzogide corrosion nwere CU 20 alloy, wdg.
2. Ala alloy na-eguzogide corrosion
Tumadi Hastelloy alloy na NI-CU alloy, wdg Ebe ọ bụ na metal NI n'onwe ya nwere a ihu na-adabere cubic Ọdịdị, ya crystallographic kwụsie ike na-enyere ya nabata ọzọ alloying ọcha karịa FE, dị ka CR, MO, wdg, ka imezuo. iguzogide Ike nke gburugburu ebe dị iche iche;N'otu oge ahụ, nickel n'onwe ya nwere ikike iguzogide corrosion, karịsịa ikike iguzogide nrụgide nrụgide nke ion chloride kpatara.Na gburugburu corrosion mbelata siri ike, gburugburu acid agwakọtara agwakọta, yana ngwọta nwere halogen ion, alloys na-eguzogide corrosion nke nickel nke Hastelloy nọchitere anya nwere uru zuru oke karịa igwe anaghị agba nchara.
3.Hastelloy bụ nke nickel-molybdenum-chromium-iron-tungsten nickel dabeere alloy.Ọ bụ otu n'ime ihe igwe ọgbara ọhụrụ na-eguzogide corrosion.Ọ na-abụkarị ihe na-eguzogide ọgwụ chlorine mmiri, chloride oxidizing dị iche iche, ngwọta nnu chloride, sulfuric acid na salts oxidizing, ma nwee ezigbo nguzogide corrosion na obere okpomọkụ na ọkara okpomọkụ hydrochloric acid.Ya mere, n'ime iri afọ atọ gara aga, a na-eji ya eme ihe na gburugburu ebe obibi siri ike, dị ka ụlọ ọrụ kemịkalụ, ụlọ ọrụ petrochemical, flue gas desulfurization, pulp na akwụkwọ, nchebe gburugburu ebe obibi na mpaghara mmepụta ihe ndị ọzọ.Ihe dị iche iche corrosion data nke Hastelloy alloys bụ ihe a na-ahụkarị, mana enweghị ike iji ha dị ka nkọwapụta, ọkachasị na gburugburu amaghi ama, a ga-ahọpụtarịrị ihe mgbe anwalechara.Enweghi Cr zuru oke na Hastelloy iji guzogide corrosion na gburugburu oxidizing siri ike, dị ka nitric acid na-ekpo ọkụ.The mmepụta nke a alloy bụ tumadi maka chemical usoro gburugburu ebe obibi, karịsịa na ọnụnọ nke agwakọta acid, dị ka ihapu ọkpọkọ nke flue gas desulfurization usoro.
