Unyango loMphezulu weLaser Cladding 

Itekhnoloji yokugquma iLaser yitekhnoloji entsha yokuguqula umphezulu eyavela ngeminyaka yoo-1970 ngophuhliso lweelaser ezinamandla amakhulu.Kuthetha ukuba itekhnoloji ye-laser yokugquma itekhnoloji yinto yokwaleka komphezulu owenziwe ngokufudumeza ngokukhawuleza kunye nokunyibilika kwengxubevange okanye umgubo weceramic kunye nomphezulu we-substrate phantsi kwesenzo se-laser beam, kwaye emva koko ukuzipholisa okuzihlaziyayo emva kokuba umqadi ususiwe ukwenza i-coating yomhlaba. kunye nesantya esiphantsi kakhulu sokuxutywa kunye ne-metallurgical bonding kunye ne-substrate material.Le yindlela yokuqinisa umphezulu ophucula kakhulu ukunyanzeliswa kokugqoka, ukuxhathisa kwe-corrosion, ukumelana nobushushu, ukuchasana kwe-oxidation kunye neempawu zombane ze-substrate surface.

Ngokomzekelo, emva kokufakwa kwe-laser ye-tungsten carbide kwii-steels ezingama-60, ubunzima bufikelela kwi-2200 HV okanye ngaphezulu, kwaye ukuxhathisa ukunxiba malunga namaxesha angama-20 kwisiseko se-60 yentsimbi.Emva kokugqunywa kwelaser ye-CoCrSiB alloy kumphezulu wentsimbi ye-Q235, ukuxhathisa kwayo kwafaniswa nokuxhathisa ukubola kokutshiza kwedangatye, kwaye eyokuqala yafunyaniswa iphezulu kakhulu kunokokugqibela.

Itekhnoloji yokugquma i-Laser ivumela ukuba izinto zifakwe ngokuchanekileyo kwaye zikhethwe ngokufakwa kobushushu obuncinci kwi-substrate ephantsi.Ukudala le bhondi yomatshini phakathi kwe-substrate kunye noluhlu yenye yezona nkqubo zichanekileyo ze-welding ezikhoyo.

Izixhobo zeLaser Cladding

Izibonelelo ngokujonga nje

• I-automation elula kunye nokudibanisa kwi-CNC kunye ne-CAD / CAM yemveliso yendalo
• Ubuncinci okanye akukho porosity kwidiphozithi (> 99.9% yoxinaniso)

Usetyenziso lweLaser Cladding Technology

Itekhnoloji yokugquma iLaser inoluhlu olubanzi lwezicelo, kwaye unokuphonononga usetyenziso oluqhelekileyo lweshishini olukhoyo ukuze uqinisekise ukuba luyahambelana nemeko yakho yosetyenziso.Kungenjalo, unako jonga iphepha lethu le-laser cladding ngolwazi oluthe kratya.Itekhnoloji yokugquma iLaser ingasetyenziselwa ukwenziwa ngokukhawuleza, ukulungiswa kwenxalenye kunye nokuphuculwa komphezulu, kwaye inenani elikhulu lezicelo ezibandakanya, ngakumbi, kwiimoto, i-FMCG, amashishini ezonyango kunye nemveliso.Idla ngokusetyenziselwa ukuhlaziya, ukuyila kunye nokulungisa iindawo ezifana nezixhobo, iishafti, iincakuba, iiiturbines, izixhobo zokomba, njl.njl. Ezi zilandelayo zezinye iimeko zesicelo eziqhelekileyo:

• Amagqabi einjini ye-aerospace kunye nokulungiswa
• Ukuthwala ukulungiswa kwejenali
• Iijenali zabalandeli kunye neendawo zokutywina (ishishini lesamente)
• I-Turbocharger impellers
• Izixhobo zokugaya
• Oomatshini bezolimo
• Iivalve zokukhupha
• Iintsimbi zepiston
• Izitshintshi zobushushu
• Iirola zenkqubo yobushushu obuphezulu, ubulukhuni kunye nokumelana nomhlwa, imilebe yevalvu kunye nezihlalo (cobalt 6)

Iingxaki ngokujonga nje

• Ngelixa i-laser cladding ineengenelo ezininzi, kukho izinto ezingeloncedo kwitekhnoloji, kubandakanya:
• Iindleko eziphezulu zezixhobo zokuvala i-laser
• Isixhobo esikhulu sithetha ukuba asiqhelekanga ukuphatheka, nangona izisombululo zentsimi ephathekayo zikhona
• Amazinga aphezulu okwakha anokukhokelela ekuqhekekeni (nangona kwezinye izinto ezi zinto zinokupheliswa kunye nolawulo olongezelelweyo lwe-thermal, olufana nokulawula ukufudumeza kwangaphambili kunye ne-post-deposition yokupholisa) Inkqubo ye-laser cladding iyatshisa kwaye ipholile ngokukhawuleza kakhulu, ukuya kwi-1012 ° C / s.Ngenxa yokumahluko kwiqondo lokushisa kunye ne-coefficients yokwandiswa kwe-thermal phakathi kwe-clad kunye ne-substrate materials, iintlobo ezahlukeneyo zeziphene zingaphuhliswa kwi-clad layer, ngokukodwa kubandakanywa i-porosity, ukuqhekeka, ukugqwesa kunye nokungalingani kwendawo.

Uvavanyo loMgangatho weLaser Cladding Layer

Kukho imiba emibini ekufuneka iqwalaselwe:

1I-Macroscopically, ukuphonononga ukumila kweshaneli egqunyiweyo, ukungalingani komphezulu, iintanda, i-porosity kunye nesantya sokuxutywa.

2Kwinqanaba le-microscopic, ukubunjwa kwentlangano efanelekileyo kunye nokukwazi ukubonelela ngeempawu ezifunekayo zihlolwe.Ukongeza, uhlobo kunye nokuhanjiswa kwezinto zeekhemikhali zomaleko wokugquma komhlaba kufuneka kumiselwe, kwaye ingqwalasela kufuneka ihlawulwe ukuhlalutya ukuba imeko yomaleko wenguqu ibonding ye-metallurgical, kunye novavanyo lobomi obusemgangathweni kufuneka lwenziwe ukuba kukho imfuneko.

Ukugqitywa komphezulu kubambe ukusebenza kunye nokubaluleka kobuhle kumacandelo emizi-mveliso.Ngemizi-mveliso ehambela phambili ngokukhawuleza, iimfuno zonyamezelo ziya ziqina kwaye kungoko ukugqitywa okungcono komphezulu kuyafuneka kwiimveliso ezichanekileyo.Amacandelo anembonakalo ekhangayo anandipha inzuzo ebalulekileyo kwimarike.Ukugqitywa kobuhle bomphandle kunokwenza umahluko omkhulu kwintsebenzo yecandelo lentengiso.
