Ukwelashwa Okungaphezulu kwe-Laser Cladding 

Ubuchwepheshe be-laser cladding ubuchwepheshe obusha bokuguqula indawo obuvele ngeminyaka yawo-1970s ngokuthuthukiswa kwama-laser anamandla amakhulu.Kusho ukuthi ubuchwepheshe be-laser surface cladding buyi-surface coating eyakhiwe ngokushisisa ngokushesha nokuncibilika kwe-alloy noma i-ceramic surface ne-substrate surface ngaphansi kwesenzo se-laser beam, bese kuba ukupholisa okuzithokozisayo ngemva kokususwa kwegobolondo ukuze kwakhiwe i-surface coating. ngesilinganiso esiphansi kakhulu sokuhlanjululwa kanye ne-metallurgical bonding ne-substrate material.Lena indlela yokuqinisa ubuso ethuthukisa kakhulu ukumelana nokugqoka, ukumelana nokugqwala, ukumelana nokushisa, ukumelana ne-oxidation kanye nezici zikagesi ze-substrate surface.

Isibonelo, ngemva kokufakwa ngelaser kwe-tungsten carbide ezinsimbini ezingu-60, ubulukhuni bufinyelela ku-2200 HV noma ngaphezulu, futhi ukumelana nokugqokwa cishe kuphindwe izikhathi ezingu-20 kunesisekelo sensimbi engu-60.Ngemuva kokufakwa kwe-laser kwe-CoCrSiB alloy ebusweni bensimbi ye-Q235, ukumelana kwayo nokugqokwa kwaqhathaniswa nokumelana nokugqwala kokufutha amalangabi, futhi eyokuqala yatholakala iphakeme kakhulu kunaleyo yakamuva.

Ubuchwepheshe be-laser cladding buvumela okokusebenza ukuthi kufakwe ngokunembile nangokukhetha ngokufaka okuncane kokushisa ku-substrate engaphansi.Ukudala lesi sibopho semishini phakathi kwe-substrate kanye nongqimba kungenye yezinqubo zokushisela ezinembe kakhulu ezitholakalayo.

Izisetshenziswa ze-Laser Cladding

Izinzuzo Ngokubuka nje

• Izendlalelo ezincibilikisiwe zimelana kakhulu nokugqwala kunezifutho ezishisayo
• Ubuchwepheshe obungcono kakhulu bokumboza noma yikuphi ukuma
• Ukushisa okuphansi ngokulinganayo kuphumela endaweni ethintekile ekushiseni (EHLA phansi kufika ku-10µm)
• Ukwenyuka kwempilo yesevisi yezingxenye ezigqokekayo
• Ingasetshenziswa nezinhlobonhlobo zezinto zokwakha, okuhlanganisa ingxubevange eyenziwe ngokwezifiso noma inhlanganisela ye-metal matrix (MMC) eklanyelwe izingxenye ezingaphansi nezingqimba.
• Ukuguquguquka ekukhetheni izinto (izinsimbi, izitsha zobumba, ngisho nama-polymers)
• Ikhwalithi ephezulu yendawo kanye ne-warpage ephansi, edinga ukwelashwa okuncane noma okungekho ngemva kokwelashwa
• Isikhathi somjikelezo omfushane kanye nokusebenza kahle kwamandla okuphezulu kwenqubo yokuvala i-laser
• Ukuzenzakalela okulula nokuhlanganiswa ku-CNC kanye ne-CAD/CAM yokukhiqiza izindawo
• I-porosity encane noma engekho ediphozini (>99.9% ukuminyana)

Izicelo Laser Cladding Technology

Ubuchwepheshe be-Laser cladding bunohlu olubanzi lwezinhlelo zokusebenza, futhi ungabuyekeza izinhlelo zokusebenza ezijwayelekile zemboni ezitholakalayo ukuze uqinisekise ukuthi ziyasifanela yini isimo sakho sokusebenzisa.Kungenjalo, ungakwazi bheka ikhasi lethu le-laser cladding ukuze uthole ulwazi olwengeziwe.Ubuchwepheshe be-laser cladding bungasetshenziselwa ukukhiqiza ngokushesha, ukulungisa izingxenye kanye nokuthuthukisa indawo, futhi inenani elikhulu lezinhlelo zokusebenza ezihlanganisa, ikakhulukazi, ezimbonini zezimoto, ze-FMCG, zezokwelapha nezokukhiqiza.Ivamise ukusetshenziselwa ukulungisa, ukwenza kanye nokulungisa izingxenye ezifana namathuluzi, shafts, izindwani, izinjini zomoya, amathuluzi okumba, njll. Okulandelayo ezinye izimo ezijwayelekile zohlelo lokusebenza:

• Ama-aerospace turbine blades kanye nokulungiswa
• Ukulungisa ijenali
• Amajenali abalandeli nezindawo zophawu (imboni kasimende)
• Ama-impeller e-Turbocharger
• Amathuluzi okubhoboza
• Imishini yezolimo
• Ama-valve okukhipha amandla
• Izinduku ze-piston
• Izishintshi zokushisa
• Amarola enqubo yokushisa ephezulu, ubulukhuni nokumelana nokugqwala, izindebe zevalvu nezihlalo (cobalt 6)

Ukubi Ngokubheka nje

• Nakuba i-laser cladding inezinzuzo eziningi, kukhona ukungalungi kobuchwepheshe, okuhlanganisa:
• Izindleko eziphezulu zemishini yokuvala i-laser
• Imishini emikhulu isho ukuthi ngokuvamile ayiphatheki, nakuba izixazululo zensimu ephathekayo zikhona
• Amazinga aphezulu okwakha angaholela ekuqhekekeni (nakuba kwezinye izinto lokhu kungaqedwa ngezinye izilawuli ezishisayo, ezifana nezilawuli zokupholisa zangaphambi kokushisa kanye ne-post-deposition) Inqubo ye-laser cladding ishisa futhi iphole ngokushesha okukhulu, kufika ku-1012°C/s.Ngenxa yomehluko wama-gradients okushisa kanye nama-coefficients wokwanda okushisayo phakathi kwezinto ezigqoke kanye ne-substrate, ukukhubazeka okuhlukahlukene kungase kuthuthuke kungqimba olugqoke, ikakhulukazi okuhlanganisa i-porosity, ukuqhekeka, ukuhlanekezela kanye nokungalingani kwendawo.

Ukuhlolwa Kwekhwalithi Yesendlalelo Se-Laser Cladding

Kunezici ezimbili okufanele zicatshangelwe:

1I-Macroscopically, ihlola ukuma kwesiteshi esigqoke, ukungalingani kwendawo, imifantu, i-porosity kanye nesilinganiso sokunciphisa.

2Ezingeni le-microscopic, ukwakheka kokuhleleka okuhle kanye nekhono lokuhlinzeka ngezakhiwo ezidingekayo kuhlolwa.Ukwengeza, uhlobo nokusatshalaliswa kwezakhi zamakhemikhali zesendlalelo se-face cladding kufanele kunqunywe, futhi kufanele kukhokhwe ukunakwa ukuze kuhlaziywe ukuthi isimo sesendlalelo soguquko siyi-metallurgical bonding, futhi ukuhlolwa kwekhwalithi yempilo kufanele kwenziwe uma kunesidingo.

Ukuqedela okungaphezulu kubamba ukubaluleka kokusebenza kanye nobuhle bezingxenye zezimboni.Njengoba izimboni zithuthuka ngokushesha, izidingo zokubekezelelana ziya ziba nzima futhi yingakho ukuqedwa okungcono kuyadingeka emikhiqizweni enembayo.Izingxenye ezinokubukeka okukhangayo zijabulela inzuzo enkulu emakethe.Ukuqedwa kobuhle bangaphandle kungenza umehluko omkhulu ekusebenzeni kokumaketha kwengxenye.

Izinsizakalo zokuqedela ingaphezulu ze-Prolean Tech zinikeza izinga kanye nokuqedwa kwangaphezulu okudumile kwezingxenye.Imishini yethu ye-CNC nobunye ubuchwepheshe bokuqeda ingaphezulu buyakwazi ukufeza ukubekezelelana okuqinile kanye nekhwalithi ephezulu, izindawo ezifanayo zazo zonke izinhlobo zezingxenye.Vele ulayishe eyakhoIfayela le-CADukuthola ikhwotheshini esheshayo, yamahhala kanye nokubonisana ngamasevisi ahlobene.
