Product Description

Kev tshawb fawb ntawm A96061 Hlau Hmoov Txhaj Moulded Parts

Lub 6061 aluminium alloy yog welded los ntawm lub tshuab nqus tsev vacuum diffusion vuam, lub zog tensile ntawm lub welded sib koom tau sim los ntawm ib tug universal xeem tshuab, thiab lub microstructure ntawm lub welded ob leeg yog soj ntsuam los ntawm ib tug optical microscope. Nyob rau hauv cov xwm txheej ntawm vuam kub ntawm 530 degree, tuav lub sij hawm ntawm 7 h thiab vuam siab ntawm 3.5 MPa, lub tensile lub zog ntawm diffusion-welded sib koom mus txog qhov siab tshaj plaws tus nqi ntawm 137.3 MPa; Tsis muaj qhov xau hauv qhov ntsuas dej siab, thiab qhov deformation ntawm aluminium alloy tsis ntau tshaj 0.5 feem pua. Qhov txhim khu kev qha vuam ntawm 6061 aluminium alloy dej-txias phaj yog paub los ntawm lub tshuab nqus tsev vacuum vuam txheej txheem. Liu Xiaochen tau npaj ib qho tshiab sintering diffusion vuam tshuab, muab piv thiab tshuaj xyuas nws qhov sib txawv thiab kev sib txuas nrog cov hmoov sintering, diffusion vuam thiab lwm yam kev sib txuas cov thev naus laus zis. M. Elsad et al. kawm txog kev cuam tshuam ntawm vuam siab ntawm microstructure thiab txhua yam khoom ntawm txhuas / tooj liab diffusion vuam pob qij txha. Lub siab pulsating tuaj yeem txhim kho cov txheej txheem sib txuas sib txuas los ntawm kev rhuav tshem cov oxide txheej ntawm cov hlau sib txuas. Nyob rau tib lub sijhawm, nce qhov vuam siab yuav cuam tshuam rau txheej txheej txheej. tsim ntau extrusion deformation (extrusion effect), lub hom phiaj yog los txhim kho lub atomic diffusion thiab mechanical zog ntawm Al-Cu pob qij txha los ntawm kev tswj cov kev sib txuas siab (welding siab), kub (600 degree) thiab lub sij hawm (60 min) tswj tseem tsis hloov pauv, thaum lub siab sib txuas sib txawv ntawm 5 thiab 12.5 MPa. Lub metallurgical thiab mechanical zog ntawm cov pob qij txha tau kawm los ntawm M. Elsad. Cov txiaj ntsig tau pom tias qhov sib txuas tsis muaj oxide yog tsim los ntawm kev sib koom ua ke hauv qhov siab ntawm 5-12.5 MPa. Qhov nce ntawm kev sib txuas siab (5-12.5 MPa) nce lub zog sib txuas (78.39-108.47 MPa) thiab qhov tob tob (11.{28}}.87 m) ntawm Al/Cu interfaces.

Txhawm rau txhim kho cov txiaj ntsig ntawm radar kav hlau txais xov Cheebtsam, Li Wendong [25] siv brazing thiab brazing-diffusion vuam sib txuas txoj hauv kev los ua cov kev sim vuam ntawm 3A21 aluminium alloy multilayer qauv. Lub morphology thiab muaj pes tsawg leeg ntawm cov pob qij txha tau txheeb xyuas los ntawm kev siv lub tshuab ntsuas hluav taws xob, lub zog spectrum thiab X-ray diffraction. Cov txiaj ntsig tau pom tias piv nrog brazing, qhov zoo ntawm kev sib koom ua ke tau los ntawm kev sib txuas ntawm brazing diffusion vuam sib xyaw yog zoo dua, thiab microstructure ntawm kev sib koom ua ke feem ntau suav nrog honeycomb Al matrix, loj heev Al-Si theem thiab thawj Si, thiab lwm yam. , Mg, Mn ntsiab tau tag nrho diffused uniformly. Los ntawm kev soj ntsuam ntawm kev sib koom tes shear test thiab pob txha, cov txiaj ntsig tau pom tias nyob rau hauv ib qho kev sib koom ua ke, lub zog sib koom ua ke nce nrog qhov nce ntawm lub sij hawm thiab lub siab, thiab lub zog shear siab tshaj plaws mus txog 81 MPa. Qhov saum npoo morphology ntawm pob txha tawg ntawm qhov sib koom ua ke yog nkig tawg, thiab muaj ntau qhov sib txawv ntawm qhov sib txawv ntawm cov qauv dej thiab ob peb dimples ntawm qhov tawg. Lub deformation ntawm lub vuam tau txais los ntawm txoj kev brazing-diffusion vuam yog tsawg dua 0.02 hli, uas ua tau raws li qhov yuav tsum tau deformation. Huang Bensheng tau tham txog tias foamed aluminium muaj ob qho tib si cov qauv thiab kev ua haujlwm. Txhawm rau muab kev ua si tag nrho rau ntau yam khoom ntawm foamed aluminium, nws feem ntau ua ke nrog cov hlau ntom ntom kom tau txais cov qauv sandwich los txhim kho nws cov khoom siv txhua yam thiab txo cov nqi. Muaj ntau txoj kev sib txuas rau cov qauv sandwich, thiab vuam yog txoj kev sib txuas zoo tshaj plaws. Ua ntej, cov yam ntxwv ntawm kev ua tau zoo thiab vuam teeb meem ntawm txhuas ua npuas ncauj yog qhia, thiab nws cov txheej txheem vuam tau sau tseg, suav nrog cov pa arc vuam, laser vuam, brazing, diffusion vuam, kev sib txhuam do vuam, plasma vuam thiab ultrasonic vuam, thiab tom qab ntawd cov kev txwv ntawm txhua qhov. txheej txheem raug tshuaj xyuas. Thaum kawg, txoj kev loj hlob ntawm cov txheej txheem vuam ntawm foamed aluminium connectors yog soj ntsuam.
