Tsis tas li ntawd, nws cov qauv nplej zoo txhim kho qhov sib sib zog nqus- qhov muaj peev xwm drilling thiab txo cov cuab yeej hnav thaum lub sijhawm ua haujlwm.
Lub ntsiab Alloying Elements
Lub ntsiab alloying ntsiab nyob rau hauv7075 aluminiumyogzinc. Thaum magnesium ntxiv rau cov alloys uas muaj kwv yees li 3% -7.5% zinc, qhov tsim ntawm MgZn₂ txhim kho cov txiaj ntsig ntawm kev kho cua sov piv rau binary aluminium-zinc alloys. Ntxiv zinc thiab magnesium cov ntsiab lus ntxiv txhim kho lub zog tensile, txawm hais tias nws tuaj yeem txo cov kev ntxhov siab corrosion cracking thiab exfoliation corrosion.
Tom qab kev kho cua sov kom zoo, 7075 txhuas tuaj yeem ua tiav qib siab zog. Me me ntawm tooj liab, chromium, thiab lwm yam tseem ceeb ntxiv rau kev ua kom zoo dua qub. Ntawm nws tempers,7075-T651 txhuastshwj xeeb tshaj yog qhov tseem ceeb thiab feem ntau suav hais tias yog ib qho ntawm ntau tshaj -cov khoom siv aluminium alloy muaj. Nws muaj lub zog zoo tshaj li cov hlau zoo tib yam, nrog rau cov khoom zoo heev thiab cov lus teb anodic. Cov ntawv thov ib txwm muaj xws li cov khoom siv dav hlau, kev tsim pwm, cov cuab yeej siv tshuab, cov khoom siv, thiab siab - lub zog, corrosion- cov yam ntxwv tiv taus.
Cov yam ntxwv ntawm 7075 Aluminium Alloy
7075 txhuas yog ib qho txias - ua haujlwm alloy yam ntxwv los ntawm lub zog siab heev thiab hardness, tshaj li ntawm ntau hom hlau. Nws muab cov kev ua haujlwm zoo corrosion, zoo heev mechanical zog, thiab muaj zog anodizing kev ua tau zoo. Nws cov qauv ua kom zoo dua qub txhim kho qhov sib sib zog nqus- qhov drilling qhov raug, txhim kho cov cuab yeej hnav tsis kam, thiab txhawb nqa xov zoo. Cov kev ua tau zoo no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Lub 7xxx Series Aluminium Alloys
Cov7xxx series txhuas alloysbelongs rau Al-Zn-Mg-Cu "super- nyuaj" aluminium tsev neeg. Taw qhia rau hauv aerospace kev siv nyob rau hauv lub lig 1940s, cov alloys tseem siv dav hauv aviation niaj hnub no. Lawv muaj cov yas zoo heev tom qab kev kho cua sov, cov lus teb zoo rau cov cua sov- kho kom muaj zog, siab zog qis dua 150 degree, thiab kev ua haujlwm kub zoo heev.
Txawm li cas los xij, lawv cov weldability yog qhov tsis zoo, thiab lawv muaj kev cuam tshuam rau kev ntxhov siab corrosion tawg, uas feem ntau xav tau kev tiv thaiv saum npoo xws li txhuas cladding. Kev kho mob kev laus theem nrab tuaj yeem txhim kho kev tiv thaiv kev ntxhov siab corrosion cracking. Nyob rau hauv annealed thiab quenched tej yam kev mob, lawv plasticity yog me ntsis qis dua li ntawm 2A12 tab sis superior rau 7A04 nyob rau hauv tib lub xeev. Piv nrog rau 7A04, 7075 daim hlau ua kom pom kev ua haujlwm zoo zoo li qub thiab qis qis qis. Qhov ntom ntom ntawm 7075 txhuas yog kwv yees li2.85 g / cm³.
