Hiki ke pani ʻia ke keleawe alumini e ka pā keleawe keleawe

Hikialumini keleawee pani ʻia me ka pā keleawe?
Ma ke ʻano he elastic alloy, ʻo ka pā keleawe tin e pili ana i kahi hui keleawe-tin i loaʻa iā Sn≤6.5%, maʻamau i loaʻa i ka P, Zn a me nā mea ala ʻē aʻe.Inā loaʻa iā ia ka P, ua kapa ʻia ʻo ia he keleawe phosphor-tin, nona ka palena elastic kiʻekiʻe, modulus elastic, kūpaʻa maikaʻi ʻO ka lole a me ke kūpaʻa corrosion, kūpono no ka hana ʻana i nā ʻāpana elastic.ʻAʻole ʻoi aku ka nui o ka alumini keleawe ma mua o 11.5%, a i kekahi manawa ua hoʻohui ʻia ka nui o ka hao, nickel, manganese a me nā mea ʻē aʻe e hoʻomaikaʻi hou i ka hana.Hiki ke hoʻoikaika ʻia ke keleawe alumini e ka mālama ʻana i ka wela, ʻoi aku kona ikaika ma mua o ka pā keleawe keleawe, a ʻoi aku ka maikaʻi o kona kūʻē ʻana i ka wela wela.Hoʻohana ʻia ia no nā wili ikaika kiʻekiʻe, nā nati, nā lima keleawe, nā apo sealing, etc., a me nā ʻāpana pale.ʻO ka hiʻohiʻona koʻikoʻi kona kūpaʻa maikaʻi.No ke keleawe alumina i loko o ka hao a me nā mea manganese, he ikaika kiʻekiʻe kona a me ke kūpaʻa.Ma hope o ke kinai ʻana a me ka hoʻoulu ʻana, hiki ke hoʻonui ʻia ka paʻakikī, a loaʻa iā ia ke kūpaʻa corrosion kiʻekiʻe kiʻekiʻe a me ke kūpaʻa oxidation.ʻO ke kūpaʻa ʻana o ka corrosion i ka lewa, ka wai hou a me ka wai kai Maikaʻi loa, ʻae ʻia ka machinability, hiki ke welded a ʻaʻole maʻalahi ka brazed, a maikaʻi ka hoʻoili ʻana i ke kaomi i ke kūlana wela.ʻO ka pā keleawe keleawe a me ke keleawe alumini he mau mea ʻaʻahu.
No ka mea, ua deformed ka indenter kila i ka wā ana, ke ʻano metala one.'O ka nui a me ka ukana o ka indenter e noho 'ole, HBS, 'oi aku ka pa'akikī o ka mea ana, a me ka pilina ma waena o HBW: 'O HB ka waiwai paakiki Brinell: ZCuSn5Pb5Zn5;ʻO ka waiwai paʻakikī o Brinell i ka maʻamau hou e wehewehe pono i ka indenter i ke ana ʻana: Ka ikaika tensile σb (MPa): HBW e pili ana i kahi indenter carbide cemented: 590HB.Ma muli o ka deformation o ke kila indenter i ka wā ana, ka hou maʻamau ho'ēmi i nā loopholes ma keia manao: ≥90;elongation δ5 (%): ≥13.'Ōlelo Aʻo: ʻO ka HWS e pili ana i ka indenter kila, no laila eia ka ʻokoʻa mua, ʻoi aku ka nui o ke ana ʻana i nā mea ʻoi aku ka paʻakikī, e hōʻemi ka maʻamau hou i nā loopholes ma kēia ʻano.
