Pākuʻi hao ma muli o ka hao/Nickel-based alloy/Nickel-based alloy/Corrosion resistance superalloy pā

ʻO nā superalloys i hoʻokumu ʻia ʻo Nickel kahi papa o nā alloys i hoʻoikaika ʻia i ka ua e hana maikaʻi ana i nā wahi wela kiʻekiʻe. ʻO nā waiwai wela kiʻekiʻe maikaʻi loa o nā superalloys nickel-based superalloys ua hopena i ka hoʻokō ʻana i kēia papa o nā alloys i nā noi aerospace.

ʻO ka superalloy ma muli o ka hao he ʻano superalloy. Hōʻike ʻia ia e ka hoʻohui ʻana i nā mea ʻē aʻe ma ke kumu o ka hao no ka alloying. E like me nā mea hoʻoheheʻe hao, ʻo ia nā superalloys nickel-based a me nā superalloys-based cobalt.

ʻO nā superalloys hoʻokumu ʻia ʻo Cobalt he mau mea i hoʻohana ʻia i ke kiʻekiʻe kiʻekiʻe a me nā kaiapuni koʻikoʻi me ka ikaika kiʻekiʻe kiʻekiʻe kiʻekiʻe, ke kūpaʻa corrosion a me ke kūpaʻa ʻaʻahu. ʻO nā superalloys e pili ana i ka Cobalt ka nui o nā mea e like me ka cobalt, chromium, tungsten, nickel a me ka alumini.

Hāʻawi ka corrosion resistant super alloys i ka hoʻonui ʻana i ka ikaika mechanical, ke kūʻē ʻana i ka deformation thermal, a me ke kūpaʻa ʻana i ka corrosion i hoʻohālikelike ʻia me nā ʻāpana kuʻuna, e koi ana i ka liʻiliʻi o ka mālama ʻana a ʻoi aku ka maikaʻi o ke kū ʻana i nā kaiapuni paʻakikī. Ke hoʻomaka nei ka hoʻoikaika ʻana e hana i nā mea hoʻoheheʻe kūʻokoʻa kūʻokoʻa hou e like me nā alloys super-based aluminika, a e hana i nā ʻano hana hou e like me ka radiolysis e hoʻohana ana i ka nano-particle synthesis no ka hoʻokumu ʻana o polycrystalline.

ʻO ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa corrosion o superalloy e hilinaʻi nui ʻia i kāna ʻano kemika a me kāna ʻano. Ke lawe nei i Inconel718 nickel-based deformed superalloy ma ke ʻano he laʻana, ʻo ka alloy he γ matrix phase, a δ phase, a carbide, a me kahi γ' a me γ "phase ikaika. ʻO nā mea kemika a me ka hoʻolālā matrix o Inconel718 alloy e hōʻike ana i kona mau waiwai mechanical ikaika, ʻoi aku ka ikaika o ke kila a ʻoi aku ka maikaʻi ma mua o ka 45 ikaika ma mua o ka tensile 45. kila.

Ma muli o ka paʻakikī a paʻakikī o ka hana ʻana o nā superalloys, ʻo ka pono o ka ʻili mīkini e hana nui i kāna hana. Eia naʻe, he mea paʻakikī loa ka superalloy i ka hana ʻana i nā mea, ʻoi aku ka paʻakikī o ka micro-strengthening mea, ʻo ke ʻano o ka paʻakikī o ka hana he koʻikoʻi, a he kiʻekiʻe ke koʻikoʻi koʻikoʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻoki ʻoki a me ka ʻoki ʻana i ka mahana ma ka ʻoki ʻana, ʻike pinepine ʻia i ka hana ʻana o ka haʻahaʻa haʻahaʻa haʻahaʻa. Ma lalo o nā kūlana ʻoki maʻamau, e hoʻopuka ka ʻili o ka superalloy i nā pilikia nui loa e like me ka papa paʻakikī, ke koʻikoʻi koena, ka papa keʻokeʻo, ka papa ʻeleʻele a me ka papa deformation palaoa.

ʻO nā superalloys nā mea hoʻohui wela o ka nickel, ka hao-nickel, a me ka cobalt i hiki ke hoʻohana ʻia i nā wela kiʻekiʻe, pinepine ma kahi o 70% o ko lākou wela hoʻoheheʻe. Hiki ke hoʻohana ʻia i nā mahana ma mua o 1050°C me nā huakaʻi a hiki i 1200°C. ʻO kēia hiʻohiʻona pale wela e lilo ia i mea koho kūpono no ka Tungsten Carbide i nā noi Pick Up.

ʻO ke ʻano nui o ka Superalloy i hoʻohana ʻia he nickel-based material i loaʻa i kahi kiʻekiʻe o ka chromium, hao, titanium, cobalt a me nā mea hoʻohui. E like me nā pūʻulu mea metala ʻē aʻe, hiki ke hoʻoponopono ʻia nā waiwai o nā superalloys me nā ʻano lapaʻau wela a / a i ʻole annealing a quenching. Ke hoʻohālikelike ʻia me nā pūʻulu waiwai ʻē aʻe, loaʻa i nā Superalloys ke kiʻekiʻe kiʻekiʻe o ka lawelawe lawelawe a me nā waiwai paʻakikī kiʻekiʻe. ʻO ka ikaika o Superalloys ka mea i koho maikaʻi loa i ka Carbide i nā noi ikaika paʻa kiʻekiʻe (> 1kg).
