E like me kā mākou e ʻike ai, he nui nā ʻano o nā mea halihali i ka mākeke, a ʻo kā mākou mau mea lawe maʻamau he ʻekolu mau ʻano o nā mea metala, nā mea metala porous a me nā mea metala ʻole.

Mea hao

ʻO nā mea hao hao, keleawe, alumini base alloy, zinc base alloy a pēlā aku i lilo i mea metala.I waena o lākou, ʻo ka mea hoʻohui, ʻike ʻia hoʻi he alloy keʻokeʻo, ʻo ia ka nui o ke alo o ke kēpau, tin, antimony a me nā metala ʻē aʻe.Hiki ke loaʻa ka ikaika haʻahaʻa ma lalo o nā kūlana o ka ukana kaumaha a me ka wikiwiki kiʻekiʻe.ʻO ke kumu he maikaʻi ke pale ʻana i ka lole, ka plasticity kiʻekiʻe, ka holo maikaʻi i ka hana, ka conductivity thermal maikaʻi, ke kūpaʻa glue maikaʻi a me ka adsorption maikaʻi me ka ʻaila.Eia nō naʻe, ma muli o kona kumukūʻai kiʻekiʻe, pono e ninini ʻia ma luna o ka lāʻau bearing o ke keleawe, ke kaula kila a i ʻole ka hao e hana i kahi uhi lahilahi.

(1) Alanui Bearing (ʻike mau ʻia ʻo Babbitt alloy a i ʻole alloy keʻokeʻo)
ʻO ke kinikini ka mea hoʻohui o ke tin, ke kēpau, antimony a me ke keleawe.Lawe ʻo ia i ka tin a i ʻole ke alakaʻi ma ke ʻano he matrix a loaʻa nā hua paʻakikī o ka tin antimony (sb SN) a me ke tin keleawe (Cu SN).Hoʻohana ka palaoa paʻa i kahi hana anti-wear, ʻoiai ka matrix palupalu e hoʻonui i ka plasticity o ka mea.He haʻahaʻa loa ka modulus elastic a me ka palena elastic o ke alo.Ma waena o nā mea halihali āpau, ʻo kāna Embeddedness a me friction compliance ka mea maikaʻi loa.He maʻalahi ke holo me ka puke pai a ʻaʻole maʻalahi ke nahu me ka puke pai.Eia naʻe, he haʻahaʻa loa ka ikaika o ka paʻa paʻa, a ʻaʻole hiki ke hana wale ʻia ka lāʻau bearing.Hiki ke hoʻopili wale ʻia i ke keleawe, ke kila a i ʻole ka hao e hoʻolei ana i ka lāʻau e like me ka uhi ʻana.He kūpono ke kaʻa ʻana no ka haʻahaʻa kaumaha, waena a me ka wikiwiki kiʻekiʻe, a he pipiʻi ke kumukūʻai.

(2) Hui keleawe
Loaʻa ka ikaika kiʻekiʻe o ke keleawe keleawe, ka antifriction maikaʻi a me ke kūpaʻa ʻana.ʻOi aku ka maikaʻi o nā waiwai ma mua o ke keleawe a ʻo ia ka mea i hoʻohana pinepine ʻia.ʻO ke keleawe ka keleawe keleawe, ke keleawe alakaʻi a me ke keleawe alumini.I waena o lākou, ʻo ke keleawe keleawe ka antifrict maikaʻi loa
