Intsimbi esekwe kwialloyi/Nickel-based alloy/Nickel-based alloy/Corrosion resistant superalloy plate

I-nickel-based superalloys yiklasi yemvula eyomeleziweyo ye-alloys eyenza kakuhle kwiindawo eziphezulu zokushisa. Iimpawu ezibalaseleyo zobushushu obuphezulu be-nickel-based superalloys ziye zaphumela ekuphunyezweni kolu didi lwee-alloys kwizicelo ezininzi ze-aerospace.

I-iron-based superalloy luhlobo lwe-superalloy. Ibonakaliswe ngokongeza ezinye izinto ngesiseko sentsimbi yokudibanisa. Ngokuhambelana ne-iron-based superalloys yi-nickel-based superalloys kunye ne-cobalt-based superalloys.

I-superalloys esekwe kwi-Cobalt zizinto ezisetyenziswa kubushushu obuphezulu kunye neendawo ezingqongileyo ezigqithisileyo ezinamandla aphezulu obushushu obuphezulu, ukuxhathisa ukubola kunye nokunganyangeki. I-superalloys esekwe kwi-cobalt ubukhulu becala yenziwe ngezinto ezifana ne-cobalt, i-chromium, i-tungsten, i-nickel kunye ne-aluminium.

I-Corrosion resistant super alloys ibonelela ngokunyuka kwamandla omatshini, ukuchasana nokuguqulwa kwe-thermal, kunye nokuchasana nokubola xa kuthelekiswa ne-alloys zendabuko, ezifuna ukugcinwa okuncinci kunye nokumelana nokumelana nokusingqongileyo. Iinzame ziyaqhubeka ukwenza ii-alloys ezinkulu ezixhathisayo kwi-corrosion ezifana ne-aluminium-based super alloys, kunye nokudala iindlela ezintsha zokwenza izinto ezifana ne-radiolysis esebenzisa i-nano-particle synthesis ukwenzela ukubunjwa kwe-polycrystalline.

Ukumelana nobushushu obuphezulu kunye nokumelana nokubola kwe-superalloy ikakhulu kuxhomekeke kukwakheka kweekhemikhali kunye nesakhiwo. Ukuthatha i-Inconel718 i-nickel-based deformed superalloy njengomzekelo, i-alloy iqukethe isigaba se-γ se-matrix, isigaba se-δ, i-carbide, kunye ne-γ eqinisiweyo kunye ne-γ "isigaba. Izinto zekhemikhali kunye nesakhiwo se-matrix ye-Inconel718 i-alloy ibonisa iipropati zayo eziqinileyo zoomatshini, amandla e-5 angcono kunye ne-plastiki amaxesha angcono, amandla angcono kunye ne-50 yentsimbi kunye namandla angcono ngaphezu kwentsimbi ye-45 Isakhiwo se-lattice esizinzile kunye nenani elikhulu lezinto eziqinisayo zifaka isandla kwiipropati zayo ezibalaseleyo.

Ngenxa yobunzima kunye nobunzima bendawo yokusebenza ye-superalloys, ingqibelelo yendawo eyenziwe ngomatshini idlala indima ebaluleke kakhulu ekusebenzeni kwayo. Nangona kunjalo, i-superalloy yinto eqhelekileyo enzima ukucubungula izinto, ukuqina kwayo kwe-micro-ukuqina kuphezulu, iqondo lokuqina komsebenzi linzima, kwaye inoxinzelelo oluphezulu lwe-chear kunye ne-conductivity ephantsi ye-thermal, amandla okusika kunye nobushushu bokusika kwindawo yokusika, idla ngokubonakala ekuqhubeni umgangatho ophantsi womphezulu, umonakalo wesixhobo unzima kakhulu kunye nezinye iingxaki. Ngaphantsi kweemeko zokusika ngokubanzi, umaleko womphezulu we-superalloy uya kuvelisa iingxaki ezinkulu kakhulu ezinje ngomaleko oqinileyo, uxinzelelo olushiyekileyo, umaleko omhlophe, umaleko omnyama kunye nomgangatho wokuguqulwa kweenkozo.

I-Superalloys zialloyi zokuxhathisa ubushushu zenikeli, i-iron-nickel, ne-cobalt ezinokusetyenziswa kumaqondo obushushu aphezulu, ngokufuthi> 70% wobushushu bazo bokunyibilika. Zingasetyenziswa kumaqondo obushushu angaphezu kwe-1050°C kunye nohambo oluya kuthi ga kwi-1200°C. Olu phawu luxhathisa ubushushu luyenza ibe ngumgqatswa ofanelekileyo endaweni yeTungsten Carbide kwizicelo zePick Up.

Olona hlobo lusetyenziswa kakhulu lweSuperalloy yimathiriyeli esekwe nickel equlethe uxinaniso oluphezulu lwechromium, intsimbi, i-titanium, i-cobalt kunye nezinye izinto ezixutywayo. Njengamanye amaqela ezinto zetsimbi, iipropathi ze-superalloys zinokulungiswa ngeendlela ezahlukeneyo zonyango lobushushu kunye / okanye ukucima kunye nokucima. Xa kuthelekiswa namanye amaqela ezinto eziphathekayo, iiSuperalloys zinelona qondo liphezulu lobushushu benkonzo kunye namaxabiso aphezulu obunzima. Amandla eSuperalloys ayenza ibe yeyona ndlela ingcono kwiCarbide kwizicelo zamandla ebhondi ephezulu (>1kg).
