Hiki i ka hui ke hoʻopilikino i ka hana ʻana o nā ʻano like ʻole o ke aniani o ke kila kila kila, hoʻokipa e hoʻouna i leka uila e nīnau mai iaʻu
1. Ma luna o ka ʻili o ke kila kila, aia nā waiho o ka lepo a i ʻole nā ʻāpana metala heterogeneous i loaʻa nā mea metala ʻē aʻe.I loko o ka ea humid, ka wai condensed ma waena o nā waihona a me ke kila kuhiliʻole e hoʻopili i nā mea ʻelua i loko o kahi micro-battery, kahi e hoʻoulu ai i kahi hopena electrochemical, ua pōʻino ke kiʻi pale, i kapa ʻia ʻo electrochemical corrosion.
2. ʻO nā waiʻawaʻawa (e like me nā mea kanu, noodle soup, sputum, a me nā mea'ē aʻe) pili i kaʻili o ke kila kila.Ma ke alo o ka wai a me ka oxygen, hoʻokumu ʻia nā ʻakika organik, a ʻo nā waikawa organik e hōʻino i ka ʻili metala no ka manawa lōʻihi.
3. Pili ka ʻili o ke kila kila i nā mea i loaʻa i nā ʻakika, nā alkalis a me nā paʻakai (e like me ka wai alkali a me ka wai lime e pāpaʻi ana mai nā paia hoʻonani), e hoʻoulu ai i ka ʻino kūloko.
4. I ka ea haumia (e like me ka lewa i loaʻa ka nui o ka sulfide, carbon oxide, nitrogen oxide), i ke alo o ka wai condensed, ka hoʻokumu ʻana o ka sulfuric acid, nitric acid, acetic acid wai kiko, e hoʻoulu ai i ka corrosion kemika. ma luna o nā kūlana hiki ke hana i ka pale kiʻiʻoniʻoni ma luna o ke kila kuhiliʻole.ʻO ka pōʻino ke kumu o ka pala.
ʻO ke kūpaʻa o ka corrosion o ke kila kila e hilinaʻi nui ʻia i kāna hui ʻana (chromium, nickel, titanium, silicon, aluminika, manganese, a me nā mea ʻē aʻe) a me ka hale o loko, a ʻo ka hana nui he chromium.Loaʻa i ka Chromium ke kūpaʻa kemika kiʻekiʻe a hiki ke hana i kahi kiʻiʻoniʻoni passivation ma ka ʻili kila e hoʻokaʻawale i ka metala mai ka honua o waho, e pale i ka pā kila mai ka hoʻoheheʻe ʻia ʻana, a hoʻonui i ke kūpaʻa corrosion o ka pā kila.Ma hope o ka luku ʻia ʻana o ke kiʻiʻoniʻoni passivation, hoʻemi ke kūpaʻa corrosion.
ʻO ka pā kila kila ka huaʻōlelo maʻamau no ka pā kila kila a me ka pā kila-ʻakika.Hoʻokomo ʻia i ka hoʻomaka ʻana o kēia kenekulia, ua hoʻokumu ka hoʻomohala ʻana i ka pā kila kila i kahi kumu waiwai nui a me ka ʻenehana no ka hoʻomohala ʻana i ka ʻoihana hou a me ka holomua ʻepekema a me ka ʻenehana.Nui nā ʻano o nā pā kila kila me nā waiwai like ʻole.Ua hoʻokumu mālie ʻo ia i kekahi mau ʻāpana i ke kaʻina hoʻomohala.Wahi a ka hale, ua māhele ʻia i ʻehā mau ʻāpana: austenitic stainless steel, martensitic stainless steel (me ka paʻakikī paʻakikī o ka ua), ferritic stainless steel, a me austenitic plus ferritic duplex stainless steel.ʻO ka hui kemika nui a i ʻole kekahi mau hiʻohiʻona o ka pā kila i hoʻokaʻawale ʻia i loko o ka chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate, haʻahaʻa carbon stainless steel plate, high molybdenum stainless steel plate, high cleanly stainless steel plate. , etc. Wahi a nā hiʻohiʻona hana a me ka hoʻohana ʻana o ka pā kila, ua māhele ʻia i loko o ka nitric acid-resistant stainless steel plate, sulfuric acid-resistant stainless steel plate, pitting corrosion-resistant stainless steel plate, stress corrosion-resistant stainless steel plate , kiʻekiʻe-ikaika kuhiliʻole kila pā, etc. E like me ka hana 'ano o ka mea kila, ua maheleia i ka haʻahaʻa wela kuhiliʻole pā kila, non-magnetic kuhiliʻole pāpaʻi, manuahi-okiʻoki kuhiliʻole pā kila, superplastic kuhiliʻole papa, etc. .Hoʻokaʻawale ʻia i loko o ka martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, etc.Nui o ka hoʻohana ʻana Nā mea hoʻohana maʻamau: nā mea hoʻololi wela o ka pulp a me ka pepa, nā mea hana mīkini, nā mea pena, nā lako hana kiʻiʻoniʻoni, nā paipu, nā mea waho no nā hale ma nā kahakai, etc.
ʻO ka pā kila kila he ʻili maʻemaʻe, ka plasticity kiʻekiʻe, ka paʻakikī a me ka ikaika mechanical, a kūpaʻa i ka corrosion e nā waikawa, nā kinoea alkaline, nā hopena a me nā media ʻē aʻe.He kila hoʻoheheʻe ʻole ʻole ia, ʻaʻole naʻe me ka ʻōpala loa.
