Kev tsim lub siab -kev ua tau zoo bimetallic ntsia hlau yuav tsum muaj cov txheej txheem tsim khoom. Cov txheej txheem tseem ceeb yog raws li nram no:
1. Substrate Machining thiab Pretreatment: Raws li cov qauv tsim, ib qho dawb paug rau cov ntsia hlau yog machined siv cov khoom tsim nyog substrate. Tom qab ntawd, qhov saum npoo yuav tsum tau clad nrog cov txheej txheej alloy yuav tsum tau ua tib zoo tu thiab kho kom tshem tawm cov roj, oxides, thiab lwm yam impurities, ua kom muaj kev ua haujlwm saum npoo av thiab tsim kom muaj kev sib raug zoo rau kev sib txuas tom ntej.
2. Alloy Layer Cladding: Qhov no yog cov kauj ruam tseem ceeb hauv bimetallic ntsia hlau tsim. Tam sim no, cov txheej txheem dav siv suav nrog:
* Plasma Arc Powder Cladding: Siv lub siab - kub plasma tsim los ntawm plasma arc raws li lub tshav kub, siab -kev ua tau zoo alloy hmoov yog tam sim ntawd melted thiab sprayed mus rau lub ntsia hlau substrate nto, tsim ib tug uniform thiab ntom cladding txheej. Cov txheej txheem no ua kom muaj cua sov, txo qhov cuam tshuam thermal ntawm lub substrate, thiab ua kom muaj cov txheej txheem zoo ntawm - zoo cladding.
* Laser Cladding: Siv lub siab- lub zog laser beam raws li qhov chaw tshav kub, cov hmoov sib xyaw ua ke ntawm cov hmoov sib tov yog melted, ua rau nws sai sai solidify ntawm substrate nto. Laser cladding muaj ntau dua precision, txo tshav kub input, thiab ib tug tsawg dilution tus nqi ntawm cov cladding txheej thiab substrate, zoo khaws cia cov khoom qub ntawm cov hlau txheej.
* Lwm cov txheej txheem, xws li tungsten inert gas welding (TIG vuam), kuj siv; qhov kev xaiv tshwj xeeb yog nyob ntawm qhov kev txiav txim siab ntawm cov ntsia hlau ua haujlwm, tus nqi, thiab kev ua haujlwm zoo.
3. Kev kho cua sov: Cov txheej txheem cladding ua rau muaj kev ntxhov siab nyob rau hauv thiab hloov microstructure. Tom qab cladding, cov ntsia hlau tau txais kev kho cua sov kom tsim nyog (xws li annealing, quenching, thiab tempering) kom tshem tawm cov kev ntxhov siab sab hauv, stabilize lub microstructure, optimize tag nrho cov khoom ntawm lub substrate thiab cladding txheej, thiab tiv thaiv deformation los yog tawg thaum siv yav tom ntej.
4. Kev Ua tiav thiab Kev Tshuaj Xyuas: Tom qab kev kho cua sov, cov ntsia hlau yuav tsum tau ua kom zoo dua qub kom ua tiav qhov tseeb qhov tseeb thiab qhov chaw tiav. Tom qab machining, nws tau dhau los ua qhov tsis zoo - kev kuaj kev puas tsuaj (xws li kev kuaj ultrasonic thiab kev ntsuas nkag mus) kom ntseeg tau tias cov txheej txheej cladding yog qhov tsis xws luag -dawb thiab zoo- khi rau lub substrate. Cov cim tseem ceeb xws li qhov tawv tawv thiab qhov ntev geometric kuj raug kuaj xyuas kom ntseeg tau tias txhua tus ntsia hlau ua tau raws li cov qauv zoo.
