Ngomhla zingama-29 kuMbasa, ulayini wokuqala wokukhiqiza wephrojekthi entsha ye-laser cladding alloy wafakwa e-Qinghai National High-tech Industrial Development Zone Equipment Manufacturing Park. Lo msebenzi wawuholwa yi-Institute of Aerospace Information, Chinese Academy of Sciences.

 I-laser cladding alloy material yitemu elijwayelekile lezinto ezisetshenziswa ngesikhathi sokuhlanganisa. Kuyinto entsha ye-alloy yensimbi. Incibilikisa izithasiselo ezihlukene ngengaphezulu le-substrate ngesikhathi esisodwa ngomsebe we-laser noma ukuncibilika, futhi yakha isibopho se-intermolecular nengaphezulu le-substrate. , Lokhu kuzothuthukisa kakhulu ukumelana nokugqokwa, ukumelana nokugqwala, ukumelana nokushisa, ukumelana ne-oxidation, nokumelana nosawoti-alkali endaweni engaphansi, futhi kuthuthukise kakhulu izakhiwo zemishini ezifana namandla aqinile namandla okukhiqiza ensimbi yesakhiwo. Lesi sihloko sinokuthuthuka okuvelele, ukuvikelwa kwemvelo kanye nokukhuthazwa okubanzi. Kuyinto eyisisekelo yokukhiqiza imishini ephezulu, futhi iyinto esetshenziswayo. Izinsizakusebenza ze-laser cladding alloy ziyacutshungulwa futhi zicutshungulwe ukuze kukhiqizwe imikhiqizo yocingo yokushisela ene-flux-cored, "okuyizintambo zokuthunga" kanye "nezinamathiselo" zensimbi, ezisetshenziswa kakhulu ekwenzeni imishini, ukwakhiwa kwemikhumbi, uphethiloli kanye ne-petrochemical, ukwakhiwa kwengqalasizinda namandla. ukuxhunywa kanye nokuqiniswa kwezingxenye ezibalulekile emikhakheni yezokuthutha kanye nobunjiniyela basolwandle kunomthelela okhethekile ongenakuthathelwa indawo kwikhwalithi yokukhiqiza imishini, futhi ithemba lemakethe libanzi.

Amandla aphezulu, ukumelana nokugqokwa okuphezulu, ukumelana nokushisa, izinto zokwakha ze-laser cladding alloy ezakhiwe futhi ezikhiqizwa ithimba lobuchwepheshe be-laser cladding le-Chinese Academy of Sciences yizinhlobonhlobo ezibalulekile zezinto zokumboza ezinobunzima obuphezulu bezobuchwepheshe kanye nokusetshenziswa okubanzi. Asetshenziswa emishinini yokumba amalahle, ukuncibilikisa insimbi, imishini esindayo nezinye izimboni. Ithole imiphumela yohlelo lokusebenza emangalisayo futhi imele izinto ezintsha kuhlelo lwe-Made in China 2025.

Kuyaqondakala ukuthi i-laser cladding iwuhlobo olusha lobuchwepheshe bokuguqulwa kwendawo obusebenzisa i-laser beam ukushisa ingaphezulu lempahla yokuvala kanye ne-substrate, ukuze izinto ezikhethekile ezidingekayo zishiselwe phezulu kwendawo yokusebenza. Uma kuqhathaniswa nobuchwepheshe obusetshenziswa kakhulu bokucwenga kanye ne-plasma spray welding (coating) ubuchwepheshe, ubuchwepheshe be-laser cladding bunochungechunge lwezici ezivelele: ukwakheka kwesendlalelo sokubopha kuncane futhi kuminyene, ukuqina kongqimba olunamathelayo kuphakeme, ukumelana nokugqwala, nokumelana nokugqoka. Okungcono; I-cladding layer kanye ne-substrate kuhlanganiswe nge-metallurgically; izinga lokuhlanjululwa kwesendlalelo se-cladding liphansi (kuphela u-5% -8%), futhi ungqimba oluncane lokumboza lungasetshenziswa ukuze kuzuzwe izidingo zokusebenza ezidingekayo; umthamo wamandla we-laser beam uphakeme, futhi izinga lokushisa lokushisa liphezulu, Ukukhethwa kwezinto zokugqoka kubanzi; indawo ethinteke ukushisa incane, futhi i-workpiece ikhubazekile kancane; izinga le-cladding lizinzile, futhi kulula ukubona ukukhiqizwa okuzenzakalelayo. 

Ngokwendlela yokuhlinzeka ngezinto zokuhlanganisa, ukuvala nge-laser kungahlukaniswa kube ukuvala kwe-laser okusethiwe kanye ne-synchronous powder-feeding laser cladding. Ukufakwa kwe-laser okusethiwe kufinyelelwa ngokuqala ngokubeka izinto zokuvala engxenyeni yokuvala phezu kwe-substrate, bese kuthwetshulwa izinto ezihlanganisayo kanye nengaphezulu le-substrate nge-laser beam. Impahla esethiwe ingaba sesimweni socingo, ibhodi, impushana, njll. Okuvame ukusetshenziswa kakhulu i-alloy powder. Ukusetha kabusha izinto kungenziwa ngokufafaza okushisayo nezindlela zokubopha. I-coating preset nge-thermal spraying method ifana, ukusebenza kahle okuphezulu, akulula ukuyikhipha, kodwa izinga lokusebenzisa i-powder liphansi, futhi inqubo yokusebenza iyinkimbinkimbi kakhulu; indlela yokusetha kabusha i-bonding isebenzisa i-varnish, ingilazi yamanzi, i-cellulose, isixazululo se-alcohol rosin, isopropyl Utshwala, iglue esobala, njll. kusetshenziswa njengezinamatheliso, ezixutshwe ne-alloy powder zibe unamathisele, zimbozwe ngaphambili engxenyeni yokugqoka bese zomiswa. Indlela yokuhlanganisa iyonga futhi ifanelekile, kodwa le ndlela ine-pre-layer elula ukuyixebula kanye nokungahambi kahle kwe-thermal. Kusetshenziswa amandla e-laser engeziwe, ukubola kwe-adhesive cishe kubangele ukukhubazeka okufana nokungcoliswa kwemvelo kanye nama-pores oqweqweni lokunamathisela, futhi kuba nzima kakhulu ukuzuza ukunamathela kwendawo enkulu.

Lo msebenzi wenziwa ngabakwa-Qinghai Zhongke Kuntai Laser Cladding New Materials Co., Ltd. Ngokusho komphathi jikelele wale nkampani uMa Youxuan, i-Qinghai inesimo sezulu esomile futhi ithuthukisa indlela yayo yokuthuthukisa uhlaza, elungele kakhulu ukukhiqizwa kwezinto ezintsha ezithinta imvelo. laser cladding ingxubevange izinto. Ngasikhathi sinye, i-laser cladding kanye nokufafaza ngesivinini esiphezulu kuyingxenye yokukhiqiza okungeziwe kanye nobuchwepheshe bokukhiqiza kabusha, obusetshenziselwa ukunakekelwa nokulungiswa kwemishini emikhulu. Bangakwazi ukusebenzela amabhizinisi amaningi ezimboni e-Qinghai ngisho nesifunda esisenyakatho-ntshonalanga, futhi babambe iqhaza ekuthuthukisweni kwesu le-"Qinghai Equipment Qinghai". Sebenzisa.
