T6 Temper txhais li cas hauv 7075
Nyob rau hauv 7075-T6 txhuas, T6 lub npe yog hais txog ib qho kev kho cua sov tshwj xeeb uas tau ua tiav los ntawm kev kho cua sov ua raws li kev laus, cov txheej txheem uas ua rau cov hlau muaj zog thiab hardness. Nyob rau hauv T6 mob, 7075 ncav cuag nws qhov siab tshaj plaws txhua yam kev ua tau zoo, feem ntau xa lub zog tensile ntawm 510-540 MPa thiab lub zog tawm los ntawm 430-480 MPa, uas ua rau nws yog ib qho ntawm cov khoom lag luam muaj zog tshaj plaws ntawm txhuas alloys.
Corrosion Resistance ntawm 7075-T6
7075-T6 txhuas muab kev tiv thaiv corrosion zoo tag nrho, tab sis nws muaj peev xwm ua rau muaj kev ntxhov siab- xeb tawg nyob rau hauv qee qhov kev pabcuam, tshwj xeeb tshaj yog thaum muaj kev ntxhov siab luv luv - kev coj mus rau hauv ib puag ncig corrosive. Qhov no yog ib qho zoo -cov ntaub ntawv tus yam ntxwv ntawm siab-zinc 7xxx-series alloys nyob rau hauv lub ncov-hnub nyoog T6 mob. Txhawm rau txhim kho kev ua haujlwm corrosion, ntau yam kev kho deg tuaj yeem siv tau, suav nrog anodizing, chromate hloov dua siab tshiab, hmoov txheej, plating thiab passivation, thiab cov txheej tiv thaiv tau pom zoo rau feem ntau sab nraum zoov lossis corrosive.
Muaj Tempers kom zoo dua Corrosion Performance
7075 yog tsim nyob rau hauv ntau tempers, txhua tus tsim los rau tej yam kev ua tau zoo yuav tsum tau. 7075-O yog lub annealed mob, muab zoo heev ductility nrog kuj tsis tshua muaj zog. 7075-T7/T73 yog cov tshuaj tshav kub kho thiab overaged los txhim khu kev tiv thaiv kev nyuaj siab-corrosion cracking. 7075-T651/T7351 yog tshav kub kub kho thiab dag zog, txhim kho kev sib npaug, 7075-T7651 yog kev kho cua sov, ncab thiab dhau los ua kom muaj kev sib xyaw ua ke ntawm lub zog siab thiab zoo dua kev ntxhov siab-corrosion tsis kam. Rau kev pabcuam dej hiav txwv lossis av noo, qhov kub siab tshaj nrog cov txheej tiv thaiv feem ntau nyiam dua liab qab T6.
Kev siv ntawm 7075-T6
7075-T6 yog siv rau hauv kev lag luam uas xav tau xws li aerospace, tsheb thiab kev tiv thaiv, hauv kev siv xws li cov khoom siv dav hlau mus rau siab - lub zog tsheb log thiab daim hlau tiv thaiv. Nyob rau hauv aerospace, nws yog dav siv rau cov txheej txheem tseem ceeb CNC-machined qhov chaw xws li fuselage thav duab, bulkheads thiab cav Cheebtsam, qhov twg muaj zog siab - rau - luj piv yog qhov tseem ceeb. Nws zoo heev qaug zog kev ua tau zoo thiab txhim khu kev qha corrosion kuj, thaum muaj kev tiv thaiv zoo, ua rau nws zoo haum rau kev pab mus sij hawm ntev nyob rau hauv aviation thiab aerospace ib puag ncig.
Kev Tiv Thaiv thiab Tsim Kev Qhia
Thaum tsim nrog 7075-T6 nyob rau hauv ib puag ncig corrosive, siv qhov tsim nyog tiv thaiv tiav, tsis txhob muaj kev ntxhov siab tensile nyob rau hauv luv luv - kev taw qhia hla, thiab xav txog kev kub ntxhov uas muaj kev ntxhov siab-corrosion tseem ceeb. Txheeb xyuas qhov xav tau kev npau taws, ua kom tiav thiab ntsuas qhov xav tau nrog tus neeg xa khoom, thiab thov cov ntaub ntawv zeb rau aerospace lossis kev tiv thaiv kev pab cuam.
