"Kuyang'ana molimba" ndi "kuphimba" ndi mawu awiri omwe amagwiritsidwa ntchito mofananamo, makamaka ndi ntchito zosiyana. Kuwotcherera ndi njira yowotcherera yomwe imagwiritsa ntchito nsalu yapamwamba kuti iwonjezere chitetezo ndi kukulitsa moyo wa chinthucho. Muli ndi ma carbides ndipo, nthawi zambiri, iyi ndi simenti ya carbide.

Kuyika ndikuyika chitsulo chosiyana pamwamba pa chitsulo china. Kuphimba kumadzagwiritsa ntchito zokutira zomwe zimakhala zofanana ndi zapansi koma nthawi zambiri zimagwiritsa ntchito zinthu zosiyana kuti zipereke phindu ku gawo lomwelo, monga kuuma kwakukulu, kukana dzimbiri, kapena kungokwaniritsa ntchito yokonzanso. Mofanana ndi kuphimba, laser hardfacing sangathe kupangidwa ndi makina ndipo ayenera pansi.

Zovuta za VS. Cladding ndondomeko

Komabe zolimba ndi zokutira ndi njira zokutira pamwamba zomwe zimakhala zosiyana ndi zinthu zomwe zimakwaniritsa zofunikira zosiyanasiyana, zonsezi zitha kukwaniritsidwa pogwiritsa ntchito njira zofananira:

•      Ma laser

•      Thermal spray

•      Flux-cored arc welding kapena FCAW

•      kuwotcherera kwa Plasma Transfer Arc [PTA]

Kusankha pakati pa hardfacing ndi cladding kumatengera mawonekedwe omwe mukufuna kupereka, zida zomwe zikukhudzidwa, komanso kumvetsetsa kwachilengedwe komwe kumayang'aniridwanso. Pa hardfacing, cholemera, chosagonjetsedwa ndi carbide / chitsulo choyikapo chingagwiritsidwe ntchito ndi laser, kupopera mankhwala, kupopera mbewu mankhwalawa, kapena kuwotcherera. Kupopera mbewu mankhwalawa ndikwabwino pa zinthu zomwe zimakhudzidwa ndi kupotoza kwa kutentha, kusiyana ndi kupopera mbewu mankhwalawa komwe kumafuna kupopera mbewu mankhwalawa ndi kuphatikizika ndi nyali. Kupopera mafuta si njira kuwotcherera; chifukwa chake, mphamvu ya mgwirizano ndiyotsika kwambiri poyerekeza ndi zokutira zomata kapena zomangika. Zowotcherera zachikhalidwe zitha kugwiritsidwa ntchito popaka wosanjikiza kwambiri (mpaka 10's of mm) wa zinthu zosavala. Laser hardfacing imakhala ndi phindu panjira zina makamaka chifukwa ndi njira yowotcherera yomwe imakhala ndi kutentha pang'ono, kutsika kochepa, komanso kusungunuka kwa carbide. Izi zonse zimathandiza kuti athe kukwaniritsa zomangira zowonda kwambiri zolimba.

Kuyika ndi njira yokutira yowotcherera yomwe imatulutsa mawonekedwe atsopano omwe amatha kugwiritsidwa ntchito ndi zida zambiri zokutira mosiyanasiyana monga ufa, waya, kapena waya. Kuphatikiza apo, njira zokulirapo zachikhalidwe zitha kugwiritsidwa ntchito monga tafotokozera pamwambapa. Monga laser hardfacing, laser cladding imakhala ndi phindu panjira zina makamaka chifukwa ndi njira yowotcherera yomwe imakhala ndi kutentha kochepa komanso kuchepetsedwa pang'ono. Izi zonse zimathandiza kuti athe kukwaniritsa zokutira zoonda kwambiri.

Laser hardfacing ndi cladding amagwiritsidwa ntchito pafupifupi msika uliwonse wamakampani ndi ntchito monga:

•      Mafuta ndi gasi

•      Zagalimoto

•      Zida zomangira

•      Agriculture

•      Migodi

•      Asilikali

•      Kupanga mphamvu

•      Kukonza ndi kukonzanso zida, ma turbine blade, ndi mainjini

Laser hardfacing ndi laser cladding onse amapereka ubwino wa kupotoza pang'ono matenthedwe, zokolola zambiri, ndi kukwera mtengo.

Lasers Mu Hardfacing Ndi Cladding Njira

Kugwiritsa ntchito ma lasers ngati gwero la kutentha mu hardfacing ndi cladding kumapereka kulondola komanso kutsika kocheperako kwa mankhwala kuti muwotcherera zida ziwiri. Amapereka njira yotsika mtengo yogwiritsira ntchito zinthu zapansi zotsika mtengo pogwiritsa ntchito zokutira zowotcherera, zomwe zimapereka dzimbiri, makutidwe ndi okosijeni, kuvala, komanso kukana kutentha. Kuchuluka kwa kupanga komwe zinthu zimatha kumalizidwa pamodzi ndi zabwino zamtengo wapatali kumapangitsa kuti laser cladding ndi hardfacing ikhale chisankho chodziwika bwino m'mafakitale ambiri.
