Kev siv dav dav ntawm laser vuam rau aluminium alloys hauv kev tsim khoom lag luam tau txais txiaj ntsig tseem ceeb rau kev txhim kho kom ruaj khov thiab kev lag luam kev lag luam, raws li nws ib txhij txhim kho weld lub zog thiab txo kev siv zog. Txawm hais tias qhov kev cia siab zoo rau cov alloys no, kev tshawb fawb tam sim no tshwj xeeb hais txog kev siv hluav taws xob txo qis thaum lawv cov txheej txheem laser vuam tseem txwv. Txoj kev tshawb no ua tiav ob lub hom phiaj ntawm kev txhim kho kev sib koom ua ke thiab txo kev siv hluav taws xob los ntawm kev sib txuas cov kab ntawm cov pa roj carbon nanotubes rau hauv 2A12 aluminium alloy. Txoj kev tshawb no txhais tau hais tias "welding efficiency," tsim ib lub zog noj qauv rau lub laser vuam ntawm aluminium alloys, thiab ua ib qho kev sib piv ntawm cov txheej txheem laser vuam nrog carbon nanotube ntxiv thiab cov txheej txheem laser vuam txheej txheem. Cov txiaj ntsig pom tau tias qhov sib ntxiv ntawm cov kab laum carbon nanotubes ua rau txo qis kev siv hluav taws xob ntau dua 33% thiab nce hauv kev sib koom ua ke ntawm 101 MPa. Tsis tas li ntawd, piv rau lwm cov txheej txheem laser vuam rau aluminium alloys qhia hauv cov ntaub ntawv uas twb muaj lawm, cov txheej txheem no nthuav tawm lub zog tseem ceeb -txuag qhov zoo. Cov kev ua tau zoo li no yog vim qhov tseeb tias cov kab carbon nanotubes nce cov aluminium alloy lub laser nqus tus nqi, thaum cov nanotubes tseem nyob rau hauv kev sib koom ua ke ua ib qho kev txhawb nqa nruab nrab. Txoj kev tshawb no muaj kev nkag siab tshiab thiab cov txheej txheem rau kev ua tiav qis-carbon, siab{13}} vuam zoo ntawm aluminium alloys.
Txoj kev tshawb no tseem ceeb txhim kho lub zog ua haujlwm ntawm aluminium alloy laser vuam thiab txo vuam zog siv los ntawm kev ntxiv cov kab ntawm cov pa roj carbon nanotubes. Ua ntej, kev sib piv kev soj ntsuam tau ua los ntawm cov txheej txheem laser vuam txheej txheem thiab cov txheej txheem laser welding nrog cov pa roj carbon nanotubes, raws li tsim lub zog noj thiab vuam efficiency qauv. Thib ob, LC-3 txheej txheem tau raug ntsuas los ntawm cov ntaub ntawv siv hluav taws xob laser qhia hauv cov ntaub ntawv muaj feem xyuam. Tib lub sijhawm, cov khoom siv kho tshuab- ib qho kev ntsuas tseem ceeb rau kev vuam zoo- tau muab tso rau hauv cov qauv ntsuas rau txhua qhov sib koom ua ke. Thaum kawg, qhov kev sib raug zoo ntawm lub zog-txuag lub peev xwm ntawm LC-3 txheej txheem thiab kev ua tau zoo ntawm cov pob qij txha welded tau qhia meej. Cov kev tshawb pom tseem ceeb tau sau tseg raws li hauv qab no:
Piv nrog rau cov txheej txheem laser vuam txheej txheem, cov txheej txheem laser welding sib txuas cov kab ntawm cov pa roj carbon nanotubes (LC-3) tau pom tias muaj 33% nce hauv vuam efficiency thiab ua tiav lub zog txuag ntawm kwv yees li 33%. Tsis tas li ntawd, LC-3 txheej txheem tau nthuav tawm cov txiaj ntsig tseem ceeb ntawm kev txo cov khoom siv.
txheeb ze rau cov txheej txheem uas twb muaj lawm, LC-3 txheej txheem ua tiav qhov siab tshaj plaws vuam efficiency, ncav cuag 60 mm² / s·kW. Rau txhuas alloys ntawm qhov sib npaug thickness, LC-3 txheej txheem kuj pom tau tias qis tshaj laser zog noj.
Lub zog zoo tshaj - txuag thiab siab - cov yam ntxwv ua tau zoo ntawm cov txheej txheem LC-3 feem ntau yog los ntawm cov khoom siv tshwj xeeb ntawm lub teeb nqus ntawm cov pa roj carbon nanotubes. Los ntawm kev sau cov vuam seam, cov nanotubes no tau txhim kho cov aluminium alloy qhov nqus ntawm lub zog laser, yog li txo qis zog laser poob thaum pib ntawm cov txheej txheem vuam.
