No ke aha i ʻoi aku ka maikaʻi o 2205 ma mua o 316L ma ke kai moana?

Me ka ulu wikiwiki ʻana o ka hoʻokele waiwai, ua hoʻomaka ka nui o ka moana a me nā waiwai kai waiwai e komo i ke kahua o ka ʻike kanaka. He hale waiwai waiwai nui ka moana, waiwai i nā kumu olaola, nā kumu ikehu a me nā kumu ikehu moana. ʻAʻole hiki ke hoʻokaʻawale ʻia ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā kumuwaiwai kai mai ka noiʻi ʻana a me ka hoʻomohala ʻana i nā mea kūikawā moana, a ʻo ka friction a me ka ʻaʻahu ʻana i nā wahi kai koʻikoʻi nā mea nui e kaohi ai i ka hoʻohana ʻana i nā mea kai a me ka hoʻomohala ʻana i nā lako kai. E noʻonoʻo i ka hana ʻino a me ka hoʻohana ʻana o 316L a me 2205 stainless steel ma lalo o ʻelua mau kūlana kai maʻamau: ʻaʻahu ʻino ka wai kai a me ka pale cathodic, a hoʻohana i nā ʻano hoʻokolohua like ʻole e like me XRD, metallography, electrochemical testing and corrosion and wear synergy e nānā i ka microstructure. Hoʻololi ʻia ka pae Mai ke kihi, ʻike ʻia ka hopena o ka hoʻoheheʻe ʻana o ke kai i ka ʻino a me nā waiwai o ke kila kila.

(1) ʻOi aku ka liʻiliʻi o ka hoʻohana ʻana o 316L ma lalo o ka haʻahaʻa haʻahaʻa. Hōʻike ka XRD a me ka loiloi metallographic i ka 316L e hoʻololi i ka martensitic transformation i ka wā e hoʻoheheʻe ai i ka wai kai, a ʻo kona hoʻololi ʻana ma kahi o 60% a ʻoi aku paha; I ka hoʻohālikelike ʻana i nā kumukūʻai hoʻololi martensite ma lalo o ʻelua mau ʻano wai kai, ua ʻike ʻia ʻo ka ʻino ʻana o ke kai e keakea i ka hoʻololi martensite.
(2) Ua hoʻohana ʻia ka nānā ʻana i ka polarization potentiodynamic a me nā ʻano hana impedance electrochemical no ke aʻo ʻana i ka mana o nā loli microstructural 316L i ka hana corrosion. Ua hōʻike nā hopena i ka hoʻololi ʻana o ka māhele martensitic i nā ʻano a me ke kūpaʻa o ka kiʻiʻoniʻoni passive ma luna o ka ʻili o ke kila kila, e alakaʻi ana i ka ʻino o ke kila kila. Ua nāwaliwali ka pale ʻana i ka corrosion; ʻO ka hoʻopili ʻana i ka electrochemical impedance (EIS) i hōʻea i kahi hopena like, a ʻo ka martensite i hana ʻia a me ka austenite untransformed i hoʻohui ʻia i ka microscopic uila huila, e hoʻololi i ke ʻano electrochemical o ke kila kila.

(3) Ka poho waiwai o316L kila kilaMa lalo o ka wai kai komo i ka friction maʻemaʻe a me ka poho waiwai (W0), ka hopena synergistic o ka corrosion ma luna o ka ʻaʻahu (S') a me ka synergistic hopena o ka ʻaʻahu ma ka corrosion (S'), aʻo ka martensitic phase transformation e pili ana i ka pilina ma waena o ka nalowale waiwai o wehewehe ʻia kēlā me kēia ʻāpana.
(4) ʻO ka hana ʻino a me ka ʻaʻahu o2205Ua aʻo ʻia ke kila ʻelua ma lalo o ʻelua kūlana kai. Ua hōʻike ʻia nā hualoaʻa: ʻoi aku ka liʻiliʻi o ke kapa kila ʻelua ma lalo o ka haʻahaʻa kiʻekiʻe, a ʻo ka hoʻoheheʻe ʻana o ke kai i hoʻokumu ʻia ka māhele σ ma ka ʻili o ke kila ʻelua. ʻO nā hoʻololi microstructural e like me nā deformations, dislocations a me ka hoʻololi ʻana i ka lattice e hoʻomaikaʻi i ka pale ʻana o ke kila pālua; i hoʻohālikelike ʻia me 316L, 2205 ʻelua-phase kila ka liʻiliʻi o ka lole a ʻoi aku ka maikaʻi o ka pale ʻana.

(5) Ua hoʻohana ʻia kahi hale hana electrochemical no ka hoʻāʻo ʻana i nā waiwai electrochemical o ka ʻili lole o ke kila pālua. Ma hope o ka paheʻe ʻana i ka wai kai, hiki ke hoʻopōʻino iā ia iho2205ua emi iho ke kila lua-phase a ua hoʻonui ka nui o kēia manawa; mai ka electrochemical impedance test method (EIS) i hoʻoholo pū i ka emi ʻana o ka waiwai kūʻē o ka ʻili o ke kila duplex a nāwaliwali ke kūpaʻa ʻana o ka wai kai; ʻO ka māhele σ i hana ʻia e ke kapa ʻauheʻe o ke kila duplex e ka wai kai e hoʻemi ana i nā mea Cr a me Mo a puni ka ferrite a me ka austenite, e hana ana i ke kila duplex i ʻoi aku ka maʻalahi i ka ʻino ʻana o ke kai, a ua maʻalahi hoʻi nā lua lua e hana i kēia mau wahi hemahema.

(6) Ka poho waiwai o2205 kila pāluaʻo ka hapa nui mai ka friction maʻemaʻe a me ka lilo ʻana o nā mea waiwai, e helu ana ma kahi o 80% a 90% o ka nui o ka poho. Hoʻohālikelike ʻia me 316L stainless steel, ʻoi aku ka nui o ka nalowale o kēlā me kēia ʻāpana o ke kila duplex ma mua o ka 316L. Liʻiliʻi.
I ka hōʻuluʻulu ʻana, hiki ke hoʻoholo ʻia he ʻoi aku ka maikaʻi o ka corrosion o ke kila 2205 i loko o ka wai kai a ʻoi aku ka maikaʻi no ka noi ʻana i ka wai kai a me ke kapa komo.
