Laser cladding yuav muab faib ua ob pawg raws li kev sib txawv hmoov noj txheej txheem: hmoov preset method thiab lub cev pub mis noj kom haum. Ob txoj kev muaj cov teebmeem zoo li no. Lub tshuab ua kom muaj cov hmoov txhuam tau yooj yim, kev ua kom lub siab tsis muaj zog, tsis muaj lub plhaub tiab, tshwj xeeb tshaj yog txoj hlua khi, uas tuaj yeem txhim kho qhov tawg ntawm cov txheej txheej, txheej txheej.
Laser cladding muaj cov yeeb yam nram qab no:
(1) Tus zauv txias yog ceev ceev (txog 106K / s), uas yog tus txheej txheem ceev nrawm, uas yog ib qho yooj yim kom zoo-grained los yog tsim kom muaj cov theem tshiab uas tsis tuaj yeem tau txais nyob rau hauv ib qho kev ua lag luam, xws li tsis ruaj tsis khov thiab amorphous lub xeev.
(2) Lub txheejtxheem txheej txheem qis yog tsawg (feem ntau tsawg tshaj li 5%), thiab nws muaj kev koom nrog lub matrix los ntawm ib qho kev sib haum xeeb hlau los yog lub zog diffusion. Los kho kho cov txheej txheem laser tsis zoo, qhov zoo uas tsis muaj qhov txo qis qis, thiab cov txheej txheem txheej thiab Lub dilution yog controllable;
(3) Cov kev tawm tswv yim thiab kev kub nyhiab yog me me, tshwj xeeb tshaj yog thaum siv lub hwj chim ceev ceev nrawm, qhov deformation tuaj yeem raug txo kom muaj kev sib luag ntawm lub rooj sib txoos.
(4) Yuav luag tsis muaj kev xaiv rau cov hmoov, tshwj xeeb tshaj yog cov kev tso dej ntawm lub siab melting point alloy nyob rau saum npoo ntawm qhov qis melting point metal;
(5) Lub thickness ntawm cladding txheej yog loj, thiab lub thickness ntawm ib leeg-kis hmoov noj yog 0.2 ~ 2.0 hli.
(6) Nws muaj peev xwm nqa tau qhov kev xaiv welding, kev siv khoom yog me me, thiab tus nqi them tus nqi;
(7) Beam aiming yuav pab tau cov chaw uas muaj chaw ncav cuag;
(8) Cov txheej txheem yog qhov yooj yim rau kev siv cuab yeej.
