Laser Cladding Technology hauv Kev Lag Luam Hlau

Tam sim no, cov tuam txhab steel feem ntau yuav tsim ntau cov khoom siv high-load, low-speed, high-precision, high-alloy bearing equipment thaum lub sij hawm ua thiab cov txheej txheem ntau lawm, thiab qee qhov yuav ua rau corrosion, hnav, tsis ua hauj lwm thiab scrapping.

Hais txog qhov teeb meem ntawm kev kho hnav, cov txheej txheem uas twb muaj lawm thiab cov teeb meem uas twb muaj lawm:
□ Hard chrome plating: Cov txheej txheem hloov kho yog nyias nyias thiab yooj yim rau tawg thiab tev tawm. Txheej thickness yog<0.1mm, mainly due to soft sealing.
□ Thermal spraying: Lub thermal deformation yog loj, lub txheej yog ib qho yooj yim los qhia dawb thaum nws nyias, thiab cov txheej txheem hloov tau yooj yim poob tawm thaum lub txheej yog tuab. Ni60 thiab Ni60+WC yog cov khoom siv tseem ceeb, thiab cov txheej txheej yog li ntawm 1-1.5mm.
□ Kev tuav arc vuam, submerged arc vuam, tungsten inert gas arc vuam (TIG), plasma arc vuam: yooj yim deform, yooj yim rau tawg, siab dilution tus nqi, tsis sib xws hardness faib, coarse cladding txheej txheej
□ Supersonic txias txau: cov nqi khiav lag luam siab, cov cuab yeej siv yooj yim, siv cov hmoov tsawg, ib puag ncig ua haujlwm hnyav, kev sib txuas ntawm lub zog tsawg dua los yog sib npaug ntawm 8 0MPa, txheej txheej yog txheej txheej txheej txheej txheej, tsis tshua muaj siab. Co-WC yog cov khoom tseem ceeb, txau thickness 0.5 hli.

Txij li thaum siv cov tshuab laser cladding, nws tuaj yeem daws tau qhov teeb meem ntawm kev ua tsis tiav thiab cov khoom siv thiab cov khoom seem, thiab tseem tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm qee yam khoom tshiab, thiab txawm tias ua tiav cov txiaj ntsig ntawm ntau lub neej. Piv txwv li, tom qab lub nruab nrab ncej, kis tau tus mob iav ncej thiab vaj tse yog kho los ntawm laser profiling cladding technology thiab sai prototyping technology, lawv muaj peev xwm rov qab mus rau lub technical indicators, As ntawm thawj qhov chaw tshiab. Tsis tsuas yog cov khoom tuaj yeem txhim kho thiab kho, tab sis kuj yog tus nqi ntawm cov tuam txhab steel tuaj yeem txuag tau zoo heev.

Laser Cladding txheej txheem:
Kuj tseem hu ua laser surfacing, nws hais txog cov txheej txheem ntawm kev xaiv cov txheej txheem ntawm cov txheej txheem txheej txheej txheej txheej txheej txheej txheej los ntawm cov txheej txheem sib txawv, ua kom sov rau lawv nrog cov kab hluav taws xob muaj zog-density laser, melting lawv nrog substrate nto, thiab solidifying lawv sai, yog li tsim. ib txheej txheej ntawm lub substrate nto uas yog metallurgically bonded nrog nws. Laser cladding muaj qhov zoo hauv qab no:
1. Lub zog ceev ntawm lub laser beam yog siab, cua kub ceev ceev, thermal nyhuv ntawm lub substrate yog me me, thiab deformation ntawm lub workpiece yog me me.
2. Los ntawm kev tswj cov input zog ntawm lub laser, cov nyhuv dilution ntawm lub substrate yuav raug txwv mus rau ib tug tsawg heev theem (feem ntau 2%-8%), yog li tswj cov kev ua tau zoo ntawm cov khoom qub cladding.

Lub laser cladding txheej yog ruaj khov rau lub substrate (metallurgical bonding), thiab cladding txheej muaj ib tug zoo qauv. Cov yam ntxwv no tau ua rau laser cladding thev naus laus zis muaj txiaj ntsig zoo hauv kev hloov kho cov khoom siv hauv kaum xyoo dhau los.
