ALLOY B-2, UNS N10665
| Alloy B-2 UNS N10665 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Soo koobid | Daxalka u adkaysta-xalka nikkel-molybdenum daawaha, Alloy B-2 waxay soo bandhigaysaa iska caabin aad u fiican oo daxalka ah ee hoos u dhigista warbaahinta sida hydrochloric acid ee heerkul ballaaran oo kala duwan, iyo sidoo kale sulfuric acid dhexdhexaad ah xitaa leh koloride xaddidan. faddarayn. Waxa kale oo loo isticmaali karaa acetic iyo phosphoric acids, iyo noocyo badan oo acids organic. Alloys-ku waxa uu leeyahay iska caabin wanaagsan oo ay u leedahay chloride-induced stress cracking crack (SCC). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Heerka Foomamka Alaabta | Dhuumaha, tubbada, xaashida, saxan, bar wareega, garabka, waalka, iyo been-abuurka. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Qaab-dhismeedka yar yar | Alloy B-2 waxa uu leeyahay qaab-dhismeed cubic waji-ku-xidhan. Kiimikada loo yaqaan 'alloy's control chemistry' ee leh birta ugu yar iyo chromium waxay yaraynaysaa halista qallafsanaantu inay dhacdo inta lagu jiro abuurista, maadaama tani ay dib u dhigayso roobabka wajiga Ni4Mo ee heerkulka u dhexeeya 700-800 ℃. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Jilayaasha | 1. Kiimikada kontoroolka leh ee ugu yar ee ka kooban birta iyo chrlmium si dib loogu dhigo samaynta β-wajiga Ni4Mo ee la dalbaday; 2. Iska caabin weyn oo daxalka ah si loo yareeyo deegaanka; 3. Iska caabin heer sare ah oo loo yaqaan sulfuric acid oo dhexdhexaad ah iyo tiro ka mid ah asiidhyada aan oksaydhismka ahayn; 4. Iska caabbinta wanaagsan ee chloride-ku-jiidashada cadaadiska-daxalka dillaaca (SCC); 5. Iska caabin wanaagsan oo u adkaysta tiro balaadhan oo ah acids organic. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Iska caabinta daxalka | Kaarboonka aadka u hooseeya iyo nuxurka silikon ee Hastelloy B-2 waxay yaraynaysaa roobabka carbides iyo wejiyada kale ee aagga kulaylka saameeya ee alxanka waxayna hubisaa iska caabbinta daxalka ku filan xitaa xaaladda alxanka. Hastelloy B-2 waxa ay muujisaa iska caabbinta daxalka ee aad u fiican ee hoos u dhigista gardarrada ah ee warbaahinta sida hydrochloric acid ee heerkul kala duwan iyo xaddi, iyo sidoo kale sulfuric acid dhexdhexaad ah xitaa iyada oo ay ku kooban tahay faddarayn koloriin ah. Waxa kale oo loo isticmaali karaa acetic iyo phosphoric acids. Iska caabbinta daxalka ugu fiican ayaa la heli karaa oo keliya haddii maaddadu ay ku jirto xaalad sax ah oo birta ah oo ay muujiso qaab-dhismeed nadiif ah. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Codsiyada | Alloy B-2 waxaa loo isticmaalaa codsiyada kala duwan ee warshadaha habka kiimikada, gaar ahaan hababka ku lug leh sulphuric, hydrochloric, fosfooraska iyo acetic acid. B-2 laguma talinayo in la isticmaalo iyada oo ay joogaan milixyada ferric ama cupric sababtoo ah milixyadani waxay sababi karaan daxalka degdega ah. milixyada Ferric ama cupric ayaa laga yaabaa inay kobcaan marka hydrochloric acid ay la timaado birta ama naxaasta. |
