Pamwamba Chithandizo cha Laser Cladding 

Ukadaulo wa laser cladding ndiukadaulo watsopano wosintha pamwamba womwe udayamba m'ma 1970 ndikupanga ma laser amphamvu kwambiri.Zikutanthauza kuti laser pamwamba cladding luso ndi ❖ kuyanika pamwamba kuti aumbike mofulumira Kutentha ndi kusungunuka aloyi kapena ceramic ufa ndi gawo lapansi pamwamba pa zochita za laser mtengo, ndiyeno kudzikonda kuziziritsa kuziziritsa pambuyo mtengo kuchotsedwa kupanga pamwamba ❖ kuyanika. otsika kwambiri dilution mlingo ndi zitsulo kugwirizana ndi gawo lapansi.Iyi ndi njira yolimbikitsira pamwamba yomwe imathandizira kwambiri kukana kuvala, kukana kwa dzimbiri, kukana kutentha, kukana kwa okosijeni ndi mawonekedwe amagetsi a gawo lapansi.

Mwachitsanzo, pambuyo povala laser ya tungsten carbide pazitsulo 60, kuuma kumafika mpaka 2200 HV kapena kupitilira apo, ndipo kukana kovala kumakhala pafupifupi nthawi 20 kuposa chitsulo choyambira 60.Pambuyo povala laser coCrSiB alloy pamwamba pa chitsulo cha Q235, kukana kwake kumafananizidwa ndi kukana kwa dzimbiri kwa kupopera mbewu kwa lawi lamoto, ndipo yoyamba idapezeka kuti ndiyokwera kwambiri kuposa yomaliza.

Ukadaulo wa laser cladding umalola kuti zinthuzo ziziyikidwa molondola komanso mosankha ndikuyika kutentha pang'ono ku gawo lapansi.Kupanga mgwirizano wamakina pakati pa gawo lapansi ndi wosanjikiza ndi imodzi mwa njira zowotcherera zomwe zilipo.

Zida Zopangira Laser Cladding

Ubwino Pang'onopang'ono

• Zigawo zosungunulidwa zimagonjetsedwa ndi dzimbiri kuposa zokutira zopopera zotentha
• Ukadaulo wabwino kwambiri wokutira mawonekedwe aliwonse
• Kutentha kocheperako kumabweretsa malo ocheperako okhudzidwa ndi kutentha (EHLA mpaka 10µm)
• Kuchulukitsa moyo wautumiki wa zida zomveka
• Itha kugwiritsidwa ntchito ndi zida zosiyanasiyana, kuphatikiza ma aloyi amtundu kapena zitsulo masanjidwe achitsulo (MMC) opangidwa ndi magawo ndi zigawo.
• Kusinthasintha pakusankha zinthu (zitsulo, ceramics, ngakhale ma polima)
• Mawonekedwe apamwamba komanso otsika kwambiri, osafuna chithandizo chamankhwala
• Nthawi yaying'ono yozungulira komanso mphamvu yayikulu ya laser cladding process
• Zosavuta zokha komanso kuphatikiza mu CNC ndi CAD/CAM kupanga mapangidwe
• Pang'ono kapena ayi porosity mu gawo (> 99.9% kachulukidwe)

Kugwiritsa ntchito Laser Cladding Technology

Ukadaulo wa laser cladding uli ndi ntchito zambiri, ndipo mutha kuwunikanso ntchito zomwe wamba zomwe zilipo kuti mutsimikizire ngati zikugwirizana ndi momwe mumagwiritsira ntchito.Kapena, mungathe onani tsamba lathu la laser cladding kuti mudziwe zambiri.Ukadaulo wa laser cladding ukhoza kugwiritsidwa ntchito popanga mwachangu, kukonza gawo ndi kuwongolera pamwamba, ndipo uli ndi ntchito zambiri kuphatikiza, makamaka, m'magalimoto, FMCG, mafakitale azachipatala ndi opanga.Nthawi zambiri amagwiritsidwa ntchito kukonzanso, kupanga ndi kukonza mbali monga zida, mitsinje, masamba, ma turbines, zida zoboola ndi zina. Izi ndi zina zomwe zimagwiritsidwa ntchito nthawi zambiri:

• Ma turbine amlengalenga ndi kukonza
• Kukonzekera kwa magazini
• Zolemba zamafani ndi madera osindikizira (makampani a simenti)
• Turbocharger impellers
• Zida zoboola
• Makina aulimi
• Mavavu otulutsa mpweya
• Mapiritsi a piston
• Zosintha kutentha
• Zodzigudubuza za kutentha kwambiri, kuuma ndi kukana dzimbiri, milomo ya valve ndi mipando (cobalt 6)

Zoyipa Pakungoyang'ana

• Ngakhale kuwala kwa laser kuli ndi zabwino zambiri, pali zovuta zina paukadaulo, kuphatikiza:
• Mtengo wokwera wa zida za laser cladding
• Zida zazikulu zikutanthauza kuti nthawi zambiri sizitha kunyamula, ngakhale njira zonyamulika zilipo
• Kumanga kwapamwamba kungayambitse kusweka (ngakhale pazinthu zina izi zikhoza kuthetsedwa ndi zowonjezera zowonjezera kutentha, monga kutentha kwa preheating ndi post-deposition controls kuzizira) Njira ya laser cladding imatentha ndikuzizira mofulumira kwambiri, mpaka 1012 ° C / s.Chifukwa cha kusiyana kwa kutentha kwa kutentha ndi ma coefficients a kukula kwa matenthedwe pakati pa zipangizo zovala ndi gawo lapansi, zolakwika zosiyanasiyana zimatha kukhala muzitsulo zophimba, makamaka kuphatikizapo porosity, kupasuka, kupotoza ndi kusagwirizana pamwamba.

Kuwunika kwa Ubwino wa Laser Cladding Layer

Pali mbali ziwiri zofunika kuziganizira:

1Macroscopically, kuyang'ana mawonekedwe a tchanelo chophimbidwa, kusafanana kwapansi, ming'alu, porosity ndi kuchuluka kwa dilution.

2Pamlingo wa microscopic, mapangidwe adongosolo labwino komanso kuthekera kopereka katundu wofunikira amawunikidwa.Kuphatikiza apo, mtundu ndi kugawa kwa zinthu zama mankhwala a pamwamba cladding wosanjikiza ziyenera kutsimikiziridwa, ndipo chidwi chiyenera kulipidwa kuti muwunike ngati momwe zinthu zilili pakusinthako ndikumangirira kwazitsulo, ndipo kuyezetsa moyo wabwino kuyenera kuchitika ngati kuli kofunikira.

Kumaliza kwapamwamba kumagwira ntchito komanso kufunikira kokongola kwa magawo a mafakitale.Mafakitale akupita patsogolo mwachangu, zololera zikuchulukirachulukira motero kutsirizitsa kwapamwamba kumafunika pakupanga zinthu zolondola kwambiri.Magawo okhala ndi mawonekedwe okopa amasangalala ndi mwayi waukulu pamsika.Kumaliza kokongola kwakunja kumatha kupanga kusiyana kwakukulu pakutsatsa kwa gawo.

Prolean Tech's surface finishing services amapereka muyezo komanso zomaliza zodziwika bwino pamagawo.Makina athu a CNC ndi matekinoloje ena omaliza pamwamba amatha kukwaniritsa kulolerana kolimba komanso mawonekedwe apamwamba, mawonekedwe amtundu wamitundu yonse.Mwachidule kweza wanuCAD wapamwambakuti mutengere mwachangu, mwaulere ndikufunsira mautumiki okhudzana nawo.
