Uyini Umehluko Phakathi Kwe-Hardfacing And Cladding
"Ubuso obunzima" kanye "nokugqoka" amagama amabili avame ukusetshenziswa ngendlela efanayo, empeleni ayizinhlelo zokusebenza ezihlukile. I-Hardfacing inqubo yokushisela esebenzisa indawo egqoke kakhulu ukuze kwengeze ukuvikeleka nokwelula impilo yento. Izinto ezishiselwe ngokuvamile iqukethe ama-carbides futhi, ezimweni eziningi, lena i-carbide ehlanganisiwe.Kubukeka njengenqwaba yobuhlalu obushiselwe obubekwe phansi buhambisana.
I-cladding iwukusetshenziswa kwensimbi engafani ebusweni kwenye insimbi. I-cladding ngokuvamile izosebenzisa okokusebenza okuyimbondela okufana nokokusebenza okuyisisekelo kodwa ezimweni eziningi kusebenzisa okokusebenza okuhlukile ukunikeza impahla ezuzisayo kuleyo ngxenye yengxenye, njengokuqina okuphezulu, ukumelana nokugqwala, noma ukuhlangabezana nomsebenzi wokulungisa. Njengokwemboza, i-laser hardfacing ayikwazi ukwenziwa ngomshini futhi kufanele igaywe.
I-Hardfacing VS. Inqubo yokuvala
Nokho ukwenza okuqinile kanye nokuvala kuyizinqubo zokumbondela phezulu ezihlukile ezicini ezibonakalayo ezihlangabezana nezidingo ezihlukene, zombili zingazuzwa kusetshenziswa izinqubo ezifanayo:
• Ama-Laser
• Isifutho esishisayo
• I-Flux-cored arc welding noma i-FCAW
• I-Plasma Transfer Arc [PTA] yokushisela
Ukukhetha phakathi kwe-hardfacing ne-cladding yehlela ezicini ofuna ukuzenza, izinto ezihilelekile, nokuqonda imvelo indawo engaphansi nayo. Ku-hardfacing, i-carbide/metal deposit esindayo, engagugi ingafakwa nge-laser, isifutho esishisayo, i-spray-fuse, noma i-welding. Ukufafaza okushisayo kungcono kakhulu ezintweni ezizwela ukuhlanekezelwa kokushisa, ngokuphambene ne-spray-fuse edinga ukufuthwa kwelangabi kanye nokuhlanganisa ngethoshi. Isifutho esishisayo akuyona inqubo yokushisela; ngakho-ke, amandla ebhondi aphansi kakhulu uma eqhathaniswa nembondela eshiselwe noma eqinile. I-weld hardfacing yendabuko ingasetshenziswa ukufaka ungqimba olujiyile kakhulu (kufika ku-10’s of mm) wezinto ezingagugi. I-Laser hardfacing inezinzuzo ngaphezu kwezinye izinqubo ngokuyinhloko ngoba iyinqubo yokushisela enokushisa okuphansi, ukuhlanjululwa okuphansi, nokuncibilika okuncane kwe-carbide. Konke lokhu kunika amandla amandla okuthola ukumbondelana kokuqina okuqinile.
I-Cladding iyinqubo yokumbondela ye-weld eveza indawo entsha ngokuphelele engasetshenziswa nezinhlobonhlobo ezinkulu zezinto zokumbondela ngezindlela ezihlukene njengempuphu, intambo, noma intambo enezintambo. Ngaphezu kwalokho, izinqubo zokumbondelana zendabuko zingasetshenziswa njengoba zibalwe ngenhla. Njenge-laser hardfacing, i-laser cladding inezinzuzo ngaphezu kwezinye izinqubo ikakhulukazi ngoba kuyinqubo yokushisela enokushisa okuphansi kanye nokuhlanjululwa okuphansi. Konke lokhu kuvumela ikhono lokuthola ukumbondelana kwezingubo ezincane kakhulu.
I-Laser hardfacing kanye ne-cladding isetshenziswa cishe kuzo zonke izimakethe zezimboni ezinezicelo ezifana nalezi:
• Uwoyela negesi
• Ezezimoto
• Izinto zokwakha
• Ezolimo
• Imayini
• Ezempi
• Ukukhiqiza amandla
• Ukulungisa nokulungiswa kabusha kwamathuluzi, ama-turbine blade, nezinjini
I-Laser hardfacing kanye ne-laser cladding kokubili kunikeza izinzuzo zokuhlanekezela okuncane kokushisa, ukukhiqiza okuphezulu, nokusebenza kahle kwezindleko.
Ama-Lasers Ku-Hardfacing And Cladding Izinqubo
Ukusebenzisa amalaser njengomthombo wokushisa ku-hardfacing kanye nokuhlanganisa kunikeza ukunemba kanye nenani eliphansi kakhulu lokuhlanjululwa kwamakhemikhali ukushisela izinto ezimbili. Ihlinzeka ngendlela engabizi kakhulu yokusebenzisa izinto ezingabizi kakhulu ze-substrate ngokusebenzisa imbondela yokushisela, ehlinzeka ngokugqwala, i-oxidation, ukuguga, nokumelana nezinga lokushisa. Izinga eliphezulu lokukhiqiza imikhiqizo engaqedwa ngalo lihlanganiswe nezinzuzo zezindleko zezinto zenza ukuvala i-laser kanye ne-hardfacing kube ukukhetha okudumile ezimbonini eziningi.
