ALOY B-2, UNS N10665

Alloy B-2 UNS N10665
Nchịkọta Ngwọta nickel-molybdenum siri ike na-eguzogide corrosion, Alloy B-2 na-egosipụta nguzogide corrosion dị mma na mgbasa ozi na-eme ihe ike dị ka hydrochloric acid n'ọtụtụ ọnọdụ okpomọkụ na ntinye uche, yana na sulfuric acid na-ajụ ase ọbụna na obere chloride. mmetọ. A pụkwara iji ya mee ihe na acetic na phosphoric acid, yana n'ọtụtụ acids organic. Alloy ahụ nwere ezigbo nguzogide chloride-induced stress corrosion cracking (SCC).

Microstructure Alloy B-2 nwere usoro cubic nke dabere na ihu. Kemistri na-achịkwa alloy nwere obere ígwè na ọdịnaya chromium na-ebelata ihe ize ndụ nke ịda mbà n'obi na-eme n'oge a na-emepụta ihe, n'ihi na nke a na-ebelata mmiri ozuzo nke usoro Ni4Mo na okpomọkụ 700-800 ℃.
Ndị agwa 1. Chemistry na-achịkwa nwere opekempe ígwè na chrlmium ọdịnaya iji kwụsị nguzobe nke β-phase Ni4Mo nyere iwu;
2. Nguzogide corrosion dị ịrịba ama na mbenata gburugburu ebe obibi;
3. Nguzogide magburu onwe ya na sulfuric acid na-ajụkarị na ọnụ ọgụgụ nke acid na-abụghị oxidizing;
4. Ezigbo iguzogide chloride na-akpata nrụgide-corrosion cracking (SCC);
5. Ezi iguzogide a dịgasị iche iche nke organic acid.
Nguzogide corrosion Ọdịnaya carbon na silicon dị oke ala nke Hastelloy B-2 na-ebelata oke mmiri nke carbides na usoro ndị ọzọ na mpaghara welds metụtara okpomọkụ ma na-eme ka nguzogide corrosion zuru oke ọbụlagodi na ọnọdụ welded. Hastelloy B-2 na-egosipụta nguzogide corrosion dị mma na mbelata mgbasa ozi dị egwu dị ka hydrochloric acid n'ọtụtụ ọnọdụ okpomọkụ na mkpokọta, yana na sulfuric acid na-etinye uche na ọkara ọbụlagodi na enwere oke mmetọ chloride. Enwere ike iji ya na acetic na phosphoric acid. Enwere ike nweta nguzogide corrosion kacha mma naanị ma ọ bụrụ na ihe ahụ dị n'ọnọdụ ọla edo ziri ezi ma gosipụta nhazi dị ọcha.
