ʻO Cobalt vs Nickel Alloy Bushings: Koho Koho no nā noi ʻaʻahu 

I loko o nā noi ʻoihana ʻaʻahu kiʻekiʻe, ʻaʻole i hāʻule mālie ka mea bushing hewa. Hōʻike ia ma ke ʻano he downtime i manaʻo ʻole ʻia, ka hoʻololi pinepine ʻana i nā ʻāpana, ke piʻi ʻana o nā kumukūʻai mālama, a me ka hōʻino ʻana i nā ʻāpana pili. Nui nā mea ʻenekinia hoʻolālā a me nā hui kūʻai e hoʻokokoke i kēia hoʻoholo me kahi lula maʻalahi: e koho i ka mea paʻakikī loa i loaʻa. Ke alakaʻi pinepine nei kēia i kahi kuhi hewa. Hiki ke nahaha ma lalo o ka hopena ha'aha'a, ho'oma'ema'e i ka wela ki'eki'e, a i 'ole e hopu i ka lubrication.

E alakaʻi kēia ʻatikala iā ʻoe i nā palena hana maoli o ka cobalt a me ka nickel alloy bushings, e hōʻike iā ʻoe pehea e pale aku ai i ka pahele "ʻoi aku ka maikaʻi ʻoi aku ka maikaʻi", a hāʻawi iā ʻoe i kahi ʻano hana i kēlā me kēia ʻanuʻu e koho ai i ka mea kūpono e pili ana i kāu mau ʻano hemahema maoli.

ʻAʻole loa he waiwai hoʻokahi wale nō ka hana ʻaʻahu. ʻO kahi koho kūleʻa e kaulike i ka pale ʻana i ka abrasion, ke kūpaʻa wela kiʻekiʻe, ka hoʻomanawanui ʻana i ka corrosion, ka paʻakikī o ka hopena, a me ka machinability. Hoʻokaʻawale kēia alakaʻi i nā ʻokoʻa maoli ma waena o ka cobalt a me ka nickel alloy bushings, wehewehe i kahi e hāʻawi ai kēlā me kēia mea i ke ola lawelawe hilinaʻi loa, a hāʻawi i kahi ala hoʻoholo kūpono i hoʻokumu ʻia i nā ʻano hemahema maoli ma mua o nā helu paʻakikī.

ʻO nā ʻano like ʻole i ke koho ʻana i ka Bushing: ʻAʻole lawa ka paʻakikī wale nō

No ka hapa nui o nā ʻenekinia, ʻo ka ʻōlelo kikoʻī mua a lākou e nānā ai ma kahi ʻikepili ʻo HRC paʻakikī. ʻOiai he mea nui ka paʻakikī, hoʻokahi wale nō ʻāpana o ka puʻupuʻu nui loa. Nui nā ʻāpana huila a me nā ʻāpana huila e hana maikaʻi ana i nā hoʻokolohua hoʻokolohua hoʻomalu i hāʻule i ka wā mua ma ke kula no ka mea ʻaʻole i nānā ke kaʻina koho i ka hoʻonohonoho piha o nā kūlana hana.

ʻElima mau mea hoʻololi e hoʻoholo i ke ola lawelawe maoli o kēlā me kēia bushing alloy:

• ʻAno ʻaʻahu: ʻAʻahu abrasive mai nā ʻāpana liʻiliʻi i loko o ka ʻōnaehana, hoʻopaʻa ʻia ma waena o nā ʻili metala paheʻe, a i ʻole ka ʻaʻahu ʻeha ma lalo o ka neʻe oscillating liʻiliʻi.
• Laulā wela hana: Ke ana wela lumi, lawelawe mau 300°C, a i ole i na spike intermittent ma luna o 600°C
• Kaiapuni kino: Hoʻomaʻemaʻe i ka ea maloʻo, ka wai, ka wai kai, nā ʻakika hoʻoheheʻe ʻia, a i ʻole nā ​​mea hoʻolaha kemika ikaika
• Hoʻouka ʻana i ka hopena: Hoʻouka paʻa paʻa, hopena māmā mau, a i ʻole haʻalulu nui
• Nā kūlana lubrication: Kiʻiʻoniʻoni ʻaila piha piha, hoʻonui i ka ʻaila ma waena, holo kokoke maloʻo, a i ʻole nalowale piha o ka lubrication ma ka wela kiʻekiʻe.

ʻO kahi mea me 60 HRC paʻakikī e hana maikaʻi loa i kahi hiʻohiʻona abrasive maʻemaʻe, maikaʻi-lubricated, haʻahaʻa haʻahaʻa. Akā, hiki i kēlā ʻāpana paʻakikī kiʻekiʻe ke haki ma hope o ka haʻalulu mechanical hoʻokahi i manaʻo ʻole ʻia, a i ʻole ke au i ka wā e pau ai ka lubrication ma 500°C. ʻO ka pahuhopu o ka koho maikaʻi ʻana ʻaʻole ia e hoʻonui i nā waiwai āpau. ʻO ia ka hoʻohālikelike ʻana i nā hiʻohiʻona hana ikaika loa o ka mea i ke ʻano hemahema i kāu noi pololei.

ʻO nā mea hoʻoheheʻe ʻia ʻo Cobalt Alloy Bushings (Stellite / T800): Nā Pono a me nā palena noi

ʻO ka Stellite bushing e pili ana i ka Cobalt a me ka lima bushing T800 kekahi o nā mea hilinaʻi hilinaʻi kūikawā kūikawā i kūkulu ʻia no ka lole a me ka wela. ʻAʻole lākou he mau ʻāpana kumu kūʻai haʻahaʻa. Hoʻolālā ʻia lākou no nā hiʻohiʻona kahi i hiki ʻole ai i nā kila maʻamau, nā keleawe, a me nā bushings stainless steel ke hāʻawi i ke ola lawelawe ʻoluʻolu.

Paʻa Paʻa Kiʻekiʻe a me ka Abrasive Wear Resistance

ʻO ke kūpaʻa ʻaʻahu koʻikoʻi o nā puʻupuʻu cobalt alloy mai kā lākou microstructure i hoʻolālā maikaʻi ʻia. Māhele ʻia nā ʻāpana carbide paʻa a me nā ʻāpana Laves paʻa - nā ʻāpana intermetallic i hana maoli ʻia i loko o nā hoʻoheheʻe ʻia ʻana o ka cobalt - ua puʻunaue like ʻia ma waena o kahi matrix kobalt paʻakikī, e hana ana i kahi ʻili e pale aku i ke komo ʻana e nā ʻāpana abrasive paʻakikī. Ma kahi o ka ʻeli ʻana i nā awāwa hohonu i loko o ka mea, paheʻe nā mea haumia ma luna o ka ʻili me ka wehe ʻole ʻana i ka nui o nā metala kumu.

ʻO kēia microstructure e kala aku iā lākou ma mua o nā kila i hoʻopaʻa ʻia i ka ʻili i nā ʻōnaehana hiki ʻole ke hoʻopaʻa ʻia. ʻOiai ke komo ʻana o ke one maikaʻi, nā ʻāpana kalapona, a i ʻole nā ​​​​palapala kaʻina hana i loko o ka interface sliding, mālama ka puʻupuʻu alloy i kona kūpaʻa nui ma mua o ka nui o nā mea hoʻokūkū.

ʻO ka ʻulaʻula paʻakikī i nā wela kiʻekiʻe

ʻO kekahi o nā mea maikaʻi loa o ka cobalt-based material, ʻo ia ka hiki ke hoʻopaʻa i ka paʻakikī paʻa i nā mahana kahi e hoʻomaka ai ka palupalu o nā kila a me nā mea hana he nui. Hiki i ka pahu hoʻoheheʻe kobalt maʻamau ke paʻa i kona ʻano paʻakikī ma luna o 500°C, a ma kekahi mau papa a hiki i 800°C.

Hoʻololi pololei kēia waiwai i ke kūʻē kūʻokoʻa i ka galling. Ke hoʻoheheʻe ʻia nā ʻili metala ʻelua me ka ʻole o ka lubrication pono, hiki i ka wela kuʻekuʻe ke hoʻopalupalu koke i nā mea maʻamau a hoʻoulu i ka pōʻino metala-a-metala. Kū'ē nā pahu hoʻoheheʻe Cobalt i kēlā hoʻoluliluli kūloko, e hilinaʻi nui ʻia i nā ʻīpuka ʻōpala turbocharger, nā ʻōnaehana EGR, nā ʻōpuʻu valve wela kiʻekiʻe, a me nā wahi ʻē aʻe e hiki ai i nā lubricants ke carbonize a nalowale paha i ka wā o ka hana hana.

ʻO Brittleness a me ka Trade-off me ka Impact Resistance

Hāʻawi ka Cobalt alloys i ka ʻaʻahu maikaʻi loa a me ka hana wela, akā hele mai kēlā hana me kahi ʻoihana kūʻai. ʻO kā lākou paʻakikī kiʻekiʻe a me ka microstructure paʻakikī e hoʻemi iki iā lākou ma mua o nā kila ʻenekinia. ʻAʻole e hoʻopaʻa ʻia ka pahu hoʻoheheʻe cobalt i ka hopena koʻikoʻi e like me ke ʻano o ka pahu kila i hoʻopaʻa ʻia a carburized paha.

Inā pili kāu noi i ka haʻalulu nui, ka hoʻouka ʻana i ka ikaika, a i ʻole ka hāmare ʻana i ka mīkini, hiki i kahi ʻāpana hoʻohui cobalt piha ke haki a ʻāʻī paha ma mua o ka pau ʻana. I kēia mau hiʻohiʻona, ʻoi aku ka maikaʻi o ka hoʻonā ʻana i ke kino bushing kila me ke alo cobalt alo, a i ʻole kahi hoʻolālā hybrid e hoʻokaʻawale i ka ukana hopena mai ka ʻili lole.

'Ōlelo Aʻo: Tsingtao CNC lako T800 kobalt-ka hoʻoheheʻe ʻia ʻana a me nā ʻāpana huila maʻamau ʻole. Loaʻa nā kumu lāʻau Stellite ma ke noi ʻana no nā koi o ka papahana.

Nickel Alloy Bushings (Monel / Inconel Family): ʻAi ʻino mua, Wear Secondary

Hoʻohālikelike pinepine ʻia nā mea hoʻoheheʻe nickel-based i nā koho cobalt, akā noho lākou i kahi hoʻolālā ʻokoʻa loa. ʻAʻole i hana ʻia nā mea e like me Monel 400 a me Inconel 718 no ke kūpaʻa abrasive ʻoi loa. ʻO ko lākou ikaika koʻikoʻi ka paʻa kemika maikaʻi loa i nā kaiapuni corrosive aggressive.

ʻO ka nickel alloy bushing e pale aku i ka chloride-induced stress corrosion pohā i ka lawelawe wai kai, e hana hilinaʻi i ka dilute sulfuric a i ʻole phosphoric acid kaiapuni, a mālama pono i ke kūkulu ʻana i ka nui o nā media oxidizing kahi e hoʻohaʻahaʻa koke ai ke kila kila. Hiki ke ʻae ʻia kona ʻano paʻakikī a me ka hoʻohana ʻana no nā haʻahaʻa haʻahaʻa haʻahaʻa, akā ʻaʻole lākou i hoʻolālā ʻia e hoʻokō i kahi pahu hoʻoheheʻe cobalt i hoʻolaʻa ʻia i kahi hiʻohiʻona lole abrasive maʻemaʻe.

Hoʻolilo kēia i nā nickel alloy bushings i koho kūpono no nā noi kahi o ka corrosion ka mea nui o ka hemahema a ʻo ka ʻaʻahu ke hopohopo lua wale nō. ʻO nā mea hoʻohana maʻamau e pili ana i nā ʻāpana pauma moana, nā ʻāpana kūloko o waho, a me nā mea hana e mālama ai i nā wai ʻino.

Manaʻo koʻikoʻi: ʻAʻole kā mākou laina huahana nui nā Nickel alloy bushings. ʻO ka ʻike hana i hāʻawi ʻia ma kēia ʻāpana no ke koho koho wale nō. Inā makemake kāu papahana i nā hoʻonā nickel-based bushing solutions, hiki iā mākou ke kūkākūkā i ka hiki ke hoʻololi ʻia i kēlā me kēia hihia.

Papa Hoʻohālikelike: Paʻa Paʻa, Kū'ē Kū'ē, Kū'ē Mahana, Mākini

Hōʻuluʻulu ka papa ma lalo nei i nā ʻokoʻa waiwai koʻikoʻi ma waena o nā māka maʻamau o ka cobalt a me ka nickel alloy bushing grades. Hōʻike nā waiwai āpau i nā pae maʻamau maʻamau o ka ʻoihana a ʻaʻole i hōʻoia ʻia i ka palena liʻiliʻi a i ʻole nā ​​helu kiʻekiʻe no kekahi huahana kikoʻī.

Ala Koho: E koho i nā mea ma ka hoʻohuli ʻana mai ke ʻano hāʻule

Ma kahi o ka hoʻomaka ʻana i kāu koho me ka papa inoa o nā waiwai waiwai, e hoʻomaka me ke ʻano hemahema āu e hālāwai ai. Hoʻopau kēia ala i ka hapa nui o nā hewa maʻamau e hele mai ana mai ka hahai ʻana i ka paʻakikī kiʻekiʻe.
