Inconel 625 Paʻa Nickel Alloy Welding Uea Ernicrmo-3 Nickel Base Alloy Uhi ʻia
ʻO Inconel kahi ʻohana o austenitic nickel chromium based super alloys.
ʻO nā alloys Inconel he mau mea kūʻē i ka corrion oxidation i kūpono no ka lawelawe ʻana ma nā wahi koʻikoʻi e pili ana i ke kaomi a me ka
wela. Ke hoʻomāhana ʻia, hana ʻo Inconel i kahi rhick, kūpaʻa, passivating oxide layer e pale ana i ka ʻili mai ka hoʻouka hou ʻana.
ikaika ma luna o kahi ākea ākea, hoihoi no nā noi wela kiʻekiʻe kahi e hāʻule ai ka alumini a me ke kila.
ma muli o nā hakahaka aniani i hoʻoulu ʻia e ka thermally. Hoʻomohala ʻia ka ikaika wela kiʻekiʻe o Inconel e ka hopena paʻa
ka hoʻoikaika ʻana a i ʻole ka paʻakikī o ka ua, ma muli o ka alloy.
ʻO ka Inconel 718 kahi huila nickel-chromium-molybdenum i hoʻolālā ʻia e pale aku i kahi ākea o nā kaiapuni koʻikoʻi koʻikoʻi, pitting a me ka crevice corrosion. Hōʻike pū ʻia kēia hui kila nickel i nā waiwai kiʻekiʻe loa, tensile, a me nā mea kolo i nā wela kiʻekiʻe. Hoʻohana ʻia kēia nickel alloy mai nā mahana cryogenic a hiki i ka lawelawe wā lōʻihi ma 1200 ° F. ʻO kekahi o nā hiʻohiʻona ʻokoʻa o ka hui ʻana o Inconel 718 ʻo ia ka hoʻohui ʻana o ka niobium e ʻae ai i ka paʻakikī makahiki e hiki ai i ka annealing a me ka hoʻopaʻa ʻana me ka paʻakikī ʻole i ka wā e hoʻomehana ai a hoʻomaha. . ʻO ka hoʻohui ʻana o ka niobium e hana me ka molybdenum e paʻakikī i ka matrix o ka alloy a hāʻawi i ka ikaika kiʻekiʻe me ka ʻole o ka hoʻoikaika ʻana i ka wela. ʻO nā mea hoʻohui nickel-chromium kaulana ʻē aʻe i paʻakikī i ka makahiki ma o ka hoʻohui ʻana o ka alumini a me ka titanium. Ua hana maʻalahi kēia mea hao nickel a hiki ke wili ʻia i loko o ke kūlana paʻakikī a i ʻole ka ua. Hoʻohana ʻia kēia superalloy i nā ʻoihana like ʻole e like me ka aerospace, ka hana kemika, ka ʻenekinia moana, nā mea hoʻomalu pollution, a me nā reactors nuklea.
ʻO nā ʻāpana wela kiʻekiʻe, e like me ka turbine blades, alakaʻi vanes, turbine disks, high pressure compressor disks, machine manufacturing and combustion chambers i hoʻohana ʻia i ka hana ʻana i nā mokulele mokulele, naval a me nā ʻenehana kinoea.
