I-Aluminiyam yokucoca ngeLaser: Susa i-Oxide kunye nePendi ngaphandle komonakalo
Uhambo olunekamva lokucoca
Ukugcina i-aluminiyam ibukeka ibukhali kunzima. I-laser ingacoca, kodwa iziphumo zixhomekeke kuhlobo lwe-alloy, ungcoliseko, kunye neeparamitha ze-laser. I-oxide, ipeyinti, ugqubuthelo, ioyile zifuna iindlela ezahlukeneyo. Ukuze uphephe umonakalo, soloko uvavanya izinto kunye nongcoliseko kuqala.
Ngena ekucoceni nge-laser.
Uluhlu Lomxholo:
1. Ngaba ukhe wasebenza nge-laser Cleaning Aluminium?
Into ethile evela kwifilimu yesayensi.
Ndiyavuma, xa ndandiqala ukuva ngokucoca nge-laser, ndandicinga ukuba kuvakala ngathi yinto evela kwimuvi yesayensi.
“I-aluminiyam yokucoca nge-laser?” ndazibuza, “Kufuneka ukuba oko kube yinto egqithisileyo.”
Kodwa xa ndadibana neprojekthi eyandenza ndadideka—ukulungisa isakhelo sebhayisekile esidala se-aluminium endandisifumene kwintengiso yeyadi—ndacinga ukuba akunakuba buhlungu ukuzama.
Kwaye ngenene, ndiyavuya ukuba ndenze njalo, kuba ukucoca nge-laser ngoku yindlela endiyisebenzisa kakhulu xa ndilungisa zonke izinto ezenziwe nge-aluminium.
2. Inkqubo yokucoca ngeLaser
Inkqubo Elula Nekhuselekileyo
1. Ngaba i-laser ingawucoca ngokukhuselekileyo u-aluminiyam?
Ewe. Ngenxa yokuba i-aluminium ifunxa amaza athile e-laser ngamandla kakhulu kune-oxide okanye iileya zayo zokugquma, inkqubo yokucoca iyama ngokuzenzekelayo kwizinto ezisisiseko, ingabangela monakalo kubushushu, imikrwelo, okanye utshintsho kubukhulu. Abaqhubi kufuneka babeke iindlela zokuskena kunye neeparamitha zamandla ukuze kufezekiswe ukucoca okufanayo kwiindawo ezinkulu ngemizuzwana.
2. Zeziphi izinto ezingcolisayo ezinokususwa, ezinje ngeengqimba ze-oxide, ioyile, ipeyinti, okanye iingubo?
Ukucocwa nge-laser kususa ngokufanelekileyo uluhlu olubanzi lwezinto ezingcolisayo ezivela kumphezulu we-aluminiyam, kubandakanya iileya ze-oxide zendalo kunye ne-anodized, iioyile zoshishino (umz., ioyile yokunyathela, ii-lubricants), iipeyinti ezahlukeneyo (i-acrylic, i-epoxy, njl.njl.), kunye neenkqubo zokugquma ezihlanganisiweyo. Kunokucoca nothuli, amasuntswana, kunye neentsalela ze-welding.
3. Ngaba ukucocwa nge-laser kubangela ukutshintsha kombala, ukunyibilika, okanye umonakalo womphezulu kwi-aluminiyam?
Phantsi kolawulo olufanelekileyo lweeparameter, hayi. Ngokungafaniyo neendlela ezirhabaxa zeekhemikhali okanye zokurhawuzelela, ukucoca nge-laser kuyakhetha kwaye kuyathamba. Amandla aphezulu kakhulu okanye useto olungalunganga lwe-pulse lunokubangela ukunyibilika komphezulu okanye ukutshintsha kombala, kodwa ngeeparameter ezilungisiweyo (ii-pulsed okanye ii-continuous-wave lasers) kunye novavanyo lwesampulu, i-substrate ye-aluminium ihlala iqinile, ingonakalanga, kwaye ayinayo i-thermal distortion.
Xa kuthelekiswa neendlela zemveli, le ndlela isusa inkunkuma enobungozi kunye nothuli ngelixa inciphisa kakhulu iingozi zokusebenza kunye nobunzima babasebenzi. Ngenxa yoko, ithathwa njengesisombululo esikhawulezayo nesikhuselekileyo kumashishini afana neenqwelo moya, ukwenziwa kweemoto, kunye nokulungiswa komphezulu ngaphambi kokuwelda.
Ngethuba ndilungisa ibhayisekile yam ye-aluminium, ndiqinisekisile ukuba ukucoca nge-laser yindlela elula nekhuselekileyo ngokwenene.

Ekuqaleni, ndandingaqinisekanga kangako.
Kodwa ke, yintoni le ndilahlekelwe yiyo?
Ndifumene inkonzo yasekuhlaleni eyayinika loo nto, kwaye kwiintsuku ezimbalwa emva koko, ndayishiya ifreyimu, ndilangazelela ukubona indlela le "milingo yelaser" eza kusebenza ngayo.
Ndathi ndakubuya ukuze ndiyithathe, ndaphantse andayibona.
Isakhelo sebhayisekile sasikhazimla, sigudile, kwaye—okona kubaluleke kakhulu—sicocekile.
Yonke i-oxidation yayisusiwe ngononophelo, ishiya i-aluminium ikwimeko yayo yendalo ecocekileyo.
Kwaye akukho monakalo.
Akukho zimpawu zokusila, akukho ndawo irhabaxa.
Yayibonakala ngathi intsha, ingenangxaki yokuyixuba okanye ukuyipolisha.
