ʻO ke kila bearing kū i ka corrosion he ʻano kūikawā o ka alloy i hoʻolālā ʻia e hoʻohui i nā waiwai halihali ukana, kūpaʻa i ke komo ʻana o nā kila bearing kuʻuna me ka hoʻoikaika ʻana i ke kūpaʻa i ka oxidation a me nā media corrosive. I ka wā e hoʻokuke ai nā ʻoihana i nā lako i nā wahi ʻoi aku ka paʻakikī.—ikehu kai, hana meaʻai, lāʻau lapaʻau, kemika, a me ka ikehu hou—ʻAʻole lawa hou nā bearings chromium kalapona kiʻekiʻe maʻamau (e laʻa, SAE 52100). Hoʻolōʻihi nā kila bearing pale i ka palaho i ke ola lawelawe, hoʻemi i ka manawa hana a me ka mālama ʻana, a hiki ke hana pono i kahi e loaʻa ai ka makū, ka paʻakai, nā waikawa a i ʻole nā mea hoʻomaʻemaʻe. Hōʻuluʻulu kēia ʻike huahana i nā ʻano nui o nā kila bearing pale i ka palaho, nā holomua hoʻomohala hou, a me nā pono koʻikoʻi e hoʻolilo iā lākou i koho makemake ʻia no nā noi koi.
ʻO nā ʻano kila kūpaʻa i ka pohō e hāʻule i loko o kekahi mau ʻano, i hoʻonohonoho pono ʻia kēlā me kēia no ke kaulike o ka paʻakikī, ka paʻakikī a me ke kūpaʻa ʻana i ke kaiapuni. Hoʻohana nui ʻia nā kila kila Martensitic (no ka laʻana ʻo AISI 440C a me nā māka X46Cr13 e pili ana) kahi e pono ai ka paʻakikī kiʻekiʻe a me ke kūpaʻa maikaʻi i ka corrosion; hiki ke mālama ʻia lākou i ka wela e hoʻokō ai i ke ola luhi pili kiʻekiʻe. Hāʻawi nā kila kila paʻakikī-precipitation (17-4PH, 15-5PH) i kahi hui ikaika o ka ikaika kiʻekiʻe, ka paʻakikī a me ke kūpaʻa i ka corrosion ma hope o ka paʻakikī ʻana o ka makahiki, kūpono no nā bearings aerospace a me nā ʻoihana. Hāʻawi nā kila kila Austenitic (e laʻa, 316L, 304) i ke kūpaʻa corrosion laulā maikaʻi loa a hoʻohana ʻia i kahi e koʻikoʻi ai ka hana corrosion, ʻoiai lākou e hāʻawi pinepine i ka paʻakikī hiki ke hiki. Hāʻawi nā mea hoʻohuihui kiʻekiʻe-nitrogen a me nā mea kūikawā (Cronidur 30 a me nā kila i hoʻoikaika ʻia e ka nitrogen) i ka luhi a me ka hana corrosion i hoʻomaikaʻi ʻia. Hāʻawi nā kila kila powder metallurgy (PM) i ka maʻemaʻe kiʻekiʻe, ka mana microstructure a me ke kūlike no nā noi koʻikoʻi.
Ua wikiwiki ka hoʻomohala ʻana i nā kila bearing kūpaʻa i ka corrosion ma o ka hoʻolālā ʻana i nā metala hao, nā hana hou o ka hoʻoheheʻe ʻana a me ke kaʻina hana, a me nā ʻenehana ʻenekinia ʻili.ʻO ka hoʻoheheʻe ʻana o ka vacuum induction hou (VIM), ka electroslag remelting (ESR) a me ka metallurgy pauka e hōʻemi i nā hoʻokomo a hoʻonui i ka maʻemaʻe, e hoʻomaikaʻi pololei ana i ke ola luhi. ʻO ka hoʻohuihui nitrogen kiʻekiʻe a me nā mea i kaulike pono ʻia o ka chromium, molybdenum a me ka nickel e hiki ai i nā kiʻiʻoniʻoni passive ikaika a me ke kūpaʻa pitting maikaʻi. Hoʻomaʻemaʻe ka mālama wela a me ka hana cryogenic i nā microstructures martensitic no ka paʻakikī mau a me ke kūpaʻa dimensional. Ma ka ʻaoʻao ʻili, hiki i ka nitriding plasma haʻahaʻa haʻahaʻa kiʻekiʻe, nā uhi PVD/DLC, a me nā liners keramika a polymer paha ke hoʻonui i ke kūpaʻa ʻana me ka ʻole o ka hoʻopilikia ʻana i ka pale ʻana i ka corrosion. ʻO ka hoʻolālā alloy computational a me ka wikiwiki o ka hoʻāʻo ʻana i ka corrosion-fatigue no nā noi hou.
ʻO nā pono a me nā ʻano hana o nā kila bearing kū i ka corrosion e unuhi ʻia i nā pono kūpono i nā lako a me nā ʻōnaehana. Hoʻemi kēia mau mea i ka pilikia o ka hydrogen embrittlement a me ka pitting i loko o nā wahi saline a i ʻole nā wahi kemika ikaika, ʻoiai e mālama ana i ka ikaika pili a me ke kūpaʻa ʻana i ka ʻaʻahu e pono ai no nā mea ʻōwili a me nā heihei. ʻO ka mālama haʻahaʻa a me ka lubrication a i ʻole ka hoʻololi pinepine ʻole e hōʻemi i nā kumukūʻai ola.—he mea koʻikoʻi no nā kahua kai, nā hana ʻai a me nā hale lapaʻau. He nui nā papa e kūlike me nā kūlana sanitary (e laʻa, FDA/USP) ma hope o ka hoʻopau pono ʻana, e kūpono ai lākou no nā noi hygienic. Eia kekahi, ʻo ka loaʻa ʻana o nā hana wela maʻamau, nā hoʻopau pololei a me nā ʻāpana PM kokoke i ka ʻupena e hiki ai i nā mea hoʻolālā ke hoʻomaikaʻi i nā bearings no ke kaumaha, ka walaʻau, a me ka pono ʻoiai e hoʻopōkole ana i nā pōʻaiapuni hōʻuluʻulu.
I ka hōʻuluʻulu manaʻo, hoʻohui nā kila bearing pale i ka corrosion i ka hana hou metallurgical a me ka hana hou e hāʻawi i nā bearings hilinaʻi a lōʻihi ke ola e hana ana i kahi e hāʻule ai nā kila kuʻuna. ʻO kā lākou mau pono nui—hoʻonui i ke kūpaʻa ʻana i ka pala, ka paʻakikī mau a me ka ikaika luhi, ka hoʻemi ʻia o ka mālama ʻana, a me ka hoʻohana ʻana ma nā wahi i hoʻoponopono ʻia a paʻakikī hoʻi—e hoʻolilo iā lākou i koho hoihoi no nā ʻenekinia a me nā loea kūʻai e ʻimi nei i ka hilinaʻi a me ke kumukūʻai haʻahaʻa o ka loaʻa ʻana. E koho i kā mākou mau hoʻonā kila bearing kū i ka corrosion no ke koho mea loea, ka hana pololei, a me ka hoʻopilikino pane.
