ALOHA B-2, UNS N10665

Huina B-2 UNS N10665
Hōʻuluʻulu manaʻo ʻO kahi huila nickel-molybdenum paʻa paʻa i ka corrosion, Alloy B-2 e hōʻike ana i ke kūpaʻa ʻino maikaʻi loa i ka hoʻohaʻahaʻa hoʻohaʻahaʻa ikaika e like me ka waika hydrochloric i kahi ākea o nā mahana a me nā hoʻopaʻa ʻana, a me ka waikawa sulfuric medium-concentrated me ka chloride palena. haumia. Hiki ke hoʻohana ʻia i loko o ka acetic a me ka phosphoric acids, a i kahi ākea o nā ʻakika organik. He kūpaʻa maikaʻi ka alloy i ka chloride-induced stress corrosion cracking (SCC).

Microstructure Loaʻa i ka Alloy B-2 kahi hoʻolālā kūkiko-kubiko. ʻO ke kemika hoʻomalu ʻia o ka alloy me ka liʻiliʻi o ka hao a me ka chromium maʻiʻo e hōʻemi i ka pilikia o ka embrittlement i ka wā o ka hana ʻana, no ka mea e hoʻopaneʻe kēia i ka ua o ka pae Ni4Mo i ka pae wela 700-800 ℃.
Nā huaʻōlelo 1. Kemika hoʻomalu ʻia me ka liʻiliʻi o ka hao a me ka chrlmium maʻiʻo e hoʻopaneʻe i ke kūkulu ʻia ʻana o ka β-phase Ni4Mo i kauoha ʻia;
2. Ke kū'ē nui i ka corrosion i ka hoʻohaʻahaʻa ʻana i ke kaiapuni;
3. ʻO ke kū'ē maikaʻi loa i ka sulfuric acid-concentrated a me ka nui o nā waikawa non-oxidizing;
4. Ke kū'ē maikaʻi i ka chloride-induced stress-corrosion cracking (SCC);
5. ʻO ke kū'ē maikaʻi i ka nui o nāʻakika organik.
Pale ʻino ʻO ka haʻahaʻa haʻahaʻa kalapona a me ka silika maʻiʻo o Hastelloy B-2 e hōʻemi ana i ka ua o ka carbide a me nā ʻāpana ʻē aʻe i ka wahi wela o nā welds a hōʻoia i ka pale ʻana i ka corrosion a hiki i ke kūlana welded. Hōʻike ʻo Hastelloy B-2 i ke kūpaʻa corrosion maikaʻi loa i nā media hoʻohaʻahaʻa hoʻohaʻahaʻa e like me ka waika hydrochloric i loko o kahi ākea o nā mahana a me nā ʻano hoʻohālikelike, a me ka waikawa sulfuric medium-concentrated ʻoiai me ka pau ʻana o ka chloride contamination. Hiki ke hoʻohana ʻia i ka acetic a me ka phosphoric acid. Hiki ke loaʻa ka pale ʻana i ka corrosion maikaʻi loa inā aia ka mea i ke kūlana metallurgical kūpono a hōʻike i kahi hale maʻemaʻe.
Nā noi Hoʻohana ʻia ʻo Alloy B-2 ma kahi ākea o nā noi i ka ʻoihana kaʻina hana kemika, ʻoi loa no nā kaʻina e pili ana i ka sulfuric, hydrochloric, phosphoric a me ka acetic acid. ʻAʻole ʻōlelo ʻia ʻo B-2 no ka hoʻohana ʻana ma mua o nā paʻakai ferric a i ʻole nā ​​paʻakai kīʻaha no ka mea hiki i kēia mau paʻakai ke hoʻopōʻino wikiwiki. Hiki ke ulu ka paʻakai ferric a i ʻole ka paʻakai kīʻaha i ka hui ʻana o ka waikawa hydrochloric me ka hao a i ʻole ke keleawe.
