Kaohi o ka ʻaukā Intergranular o Austenitic kuhiliʻole

Ma waena o nā ʻano like ʻole o ke kila kila, hōʻike ka corrosion intergranular ma kahi o 10%. E hoʻēmi ia i ka mana hoʻopaʻa ma waena o nā hua. Ma lalo o ka hana o ke koʻikoʻi, maʻalahi ka ʻūlū a haki hoʻi i ka pauka, a hūnā loa ia. ʻAʻole ʻikea ʻia i kona ʻano.

I ka manawa like, ʻo ia nō ke kumu nui o ka hoʻoulu ʻana i ka popopo ʻē aʻe. ʻO ka corrosion intergranular o ka austenitic stainless steel i kumu nui ʻia e ka nele o Cr i ka palena palena o ka palaoa, a hana maʻalahi ʻo C i nā hui me Cr, kahi e hoʻemi ai i ka ʻike Cr. No kēia kumu, ʻo nā hana pale no ka ʻino intergranular:

　　 1. ʻO ka haku mele a me ka hoʻonohonoho ʻana

　　(1) C maʻiʻo

　　ʻO ka ʻike C i ke kila ka mea nui e hoʻopili ana i ka ʻaukā intergranular o ke kila kila ʻaila. Ma ka ʻaoʻao hoʻokahi, kaohi pololei i ka ʻike C e kaohi i ka ʻike kalapona o ka metala kumu a me ke koʻokoʻo paʻa ma lalo o 0.08%; ma ka ʻaoʻao ʻē aʻe, e hoʻohui ana i nā mea hoʻopaʻa e like me Ti a me Nb i nā mea hao kumu a me nā mea hao i ka pilina paʻa no C. Hoʻohui ʻia ke kalapona me Cr ma mua o ia, a ua hoʻokumu ʻia kahi hui paʻa.

　　(2) ʻO ka hui Biphasic

　　 e hoʻomaikaʻi maikaʻi ka hanana pālua-pae i ka hiki ke pale aku i ka ʻaukā intergranular. Ma ka lima hoʻokahi, e hoʻohui ana i nā mea e hana ana i ka ferrite, e like me chromium, silicon, aluminika, molybdenum, a pēlā aku. ma ka lima ʻē aʻe, koho i kahi mea hao e loaʻa nā mea hana ferrite ʻoi aku.

　　2, kaʻina hoʻoheheʻe

　　(1) Aia ka mahana i ka mahana wela o 450 ~ 850 ℃, ʻoiai ʻo 650 ℃ ka wahi wela weliweli loa (ʻike ʻia ʻo ia ka ʻāpana mahana sensitization) kahi e kū ai ka corrosion intergranular. No laila, ke hoʻopaʻa hao kila, hiki ke hoʻohana ʻia kahi pā keleawe ma lalo o ka mea hoʻoheheʻe, a i ʻole hiki ke ninini pololei ʻia ka wai ma ka hope o ka mea hao e hoʻomaʻalili koke, e hoʻemi ana i ka manawa noho i kēia pae wela, kahi hana kūpono e hoʻomaikaʻi ai. ke kūpaʻa kūpaʻa o ka ami. .

　　(2) ʻO ka hoʻonui ʻana o ka hoʻokomo wela wela e hōʻeleu i ka pala o ke kila kuhiliʻole austenitic. I ke kaʻina hana hoʻoheheʻe, hiki ke hoʻohana ʻia i kēia manawa liʻiliʻi, ka wikiwiki kuʻihao kiʻekiʻe, arc pōkole, kuʻihao multi-pass a me nā ʻano hana e hōʻemi i ke komo wela. Lawe i ke komo wela o ka hoʻowahāwahā a hele wikiwiki i loko o ka ʻāpana mahana wela e pale ai i ka hoʻowahāwahā intergranular i ka wahi i pā ʻia i ka wela.

　　3, lāʻau ma hope o ka hoʻoheheʻe ʻana

　　 Ma hope o ke kuʻihao, hoʻomaʻamaʻa hou i ka hui welded o austenitic mea kila kila i 1050 ~ 1100 ℃, hoʻoponopono hou ʻana i ka hopena, a i ʻole ke kau hou ʻana i 850 ~ 900 ℃, e mālama no 2h, a mālama i ka mālama homogenization e hoʻopau i ka wahi chromium-pau.

E ʻoluʻolu e mālama i ke kumu a me ka helu wahi o kēia ʻatikala no ka paʻi hou ʻana: Kaohi o ka ʻaukā Intergranular o Austenitic kuhiliʻole
