Aero-injini ndechimwe chezvakanyanya kukosha zvikamu zvendege.Izvi zvinodaro nekuti ine zvakati wandei zvinodiwa zvehunyanzvi uye inonetsa kugadzira.Semudziyo wakakosha wesimba mukubhururuka kwendege, ine zvakanyanyisa zvinodiwa zvekugadzirisa zvinhu.Iyo ine zvimiro zvehuremu huremu, kusimba kwepamusoro, kupikisa tembiricha, oxidation resistance uye corrosion resistance, uye iyo yepamusoro-soro zvimiro zve superalloy inoita kuti isangane nezvinodiwa zveaero-injini zvinhu.
Superalloy zvinhu zvinogona kuchengetedza kuita kwakanaka pakupisa kuri pamusoro pe600 ° C uye pasi pemamwe mamiriro ekushushikana.Kubuda kwezvinhu zve superalloy ndiko kusangana nezvinodiwa zvemazuva ano emidziyo yemuchadenga.Mushure memakore ekushanduka kwezvinhu, superalloys dzave zvinhu zvakakosha zveaerospace midziyo yekugadzira inopisa-kuguma zvikamu.Zvinoenderana nemishumo yakabatana, mune aero-injini, Kushandiswa kwayo kunodarika hafu yeinjini yese zvinhu.
Mumainjini emazuva ano, kushandiswa kwezvinhu zvesuperalloy zvakati kurei, uye zvinhu zvakawanda zveinjini zvinogadzirwa zvine masuperalloys, zvakadai semakamuri anobvira moto, maguide vanes, maturbine blades, uye turbine disk casings, maringi, uye maafterburners.Zvikamu zvakaita semakamuri ekupisa uye miswe yemuswe inogadzirwa uchishandisa superalloy zvinhu.
Kushandiswa kwe superalloy mune aeroengine
Nekuenderera mberi kwekushanduka kweteknolojia uye kuenderera mberi kudzika kwemunda wekuongorora, tsvakurudzo yerhenium-ine imwe crystal blades uye itsva superalloys icharamba ichiongororwa.Zvishandiso zvitsva zvichawedzera simba idzva kumunda wekugadzira michina yeaerospace mune ramangwana.
1. Tsvagiridzo pamablades ekristaro imwechete ane rhenium
Zvimwe zvidzidzo zvakaratidza kuti kana kugadzira zvinhu zvine imwechete crystal kuumbwa, zvese alloy zvivakwa uye maitiro ekugadzirisa zvinhu zvinofanirwa kuverengerwa, nekuti makristasi ega anofanirwa kushandiswa munzvimbo dzine hutsinye, saka mamwe maalloying zvinhu ane akakosha maitiro anowanzo kuwedzerwa kune zvinhu zvekuvandudza.single crystal properties.Nekuvandudzwa kweimwe crystal alloys, makemikari emusanganiswa akachinja.Muzvinyorwa, kana zvikamu zveboka replatinamu (zvakadai seRe, Ru, Ir elements) zvakawedzerwa, zviri mukati mezvinhu zvinoramba W, Mo, Re, uye Ta zvinogona kuwedzerwa.Wedzera huwandu hwehuwandu hwezvinhu zvakanyanya kuoma kunyungudika, kuitira kuti zvinhu zvakadai seC, B, Hf zvigone kuchinjwa kubva pa "kubviswa" nyika kuenda kune "yakashandiswa" nyika;kuderedza zviri muCr.Panguva imwecheteyo, kuwedzera zvimwe zvinhu zvealloying zvinogona kuita kuti zvinhu zvichengetedze kugadzikana kwakasiyana mune zvakasiyana zvekuita kwezvinhu zvinodiwa.
Kushandiswa kwerhenium-ine imwe crystal blades inogona kuvandudza zvakanyanya kupisa kwayo uye kuwedzera simba rekukambaira.Kuwedzera 3% rhenium kune imwechete crystal alloy uye kuwedzera zvakakodzera zviri mukati mecobalt uye molybdenum zvinhu zvinogona kuwedzera tembiricha kuramba ne30 ° C, uye iyo yakasimba simba uye oxidation corrosion kuramba inogona zvakare kuve muchiyero chakanaka.nyika, iyo ichave inobatsira kune yakakura-chiyero kushandiswa kwerhenium-ine imwe chete crystal blades mumunda weaerospace.Kushandiswa kwerhenium-ine imwe crystal zvinhu zveaero-injini turbine blades itsika mune ramangwana.Single crystal blades ane mabhenefiti ari pachena maererano nekupisa tembiricha, kupisa kuneta simba, oxidation kuramba uye corrosion resistance.
2. Tsvakurudzo pamusoro pema superalloys matsva
Kune akawanda marudzi ezvishandiso zvitsva zve superalloy, izvo zvinonyanya kuwanda ihupfu superalloy, ODS alloy, intermetallic compound uye yakanyanya tembiricha yesimbi inozvigadzika zvinhu.
Powder superalloy zvinhu:
Iine zvakanakira chimiro chakafanana, goho repamusoro uye kuita kwakanaka kuneta.
Intermetallic makemikari:
Inogona kuderedza huremu hwezvikamu uye kuvandudza kushanda, iyo inonyatsokodzera kugadzira masimba ekufambisa masimba.
ODS alloys ane:
Yakanakisa tembiricha yepamusoro inokambaira kuita, yakanyanya tembiricha oxidation kuramba
High-tembiricha simbi-based self-lubricating zvinhu:
Inonyanya kushandiswa kubudisa yakakwirira-yepamusoro-yega yega-lubricating bearings, iyo inowedzera simba rekutakura uye inowedzera simba rekutakura.
Nekuwedzera kwekushandiswa kwe superalloy yakaoma machubhu mune aero-injini, kudiwa kwavo kucharamba kuchiwedzera mune ramangwana remuchadenga munda.
