Ukucoca ngelaser kusebenza njani kwinqwelomoya?

Itekhnoloji yokucoca iLaserisetyenziswa ikakhulu kunyango lomphezulu womzimba wenqwelomoya kwishishini le-aerospace.Xa ulungisa kwaye ugcina inqwelomoya, kuyimfuneko ngokusisiseko ukususa ipeyinti endala phezu komhlaba ukuze kutshizwe ioli entsha yesanti okanye ibrashi yentsimbi kunye nezinye iindlela zemveliukucoca umphezuluifilimu yepeyinti.

Emhlabeni,iinkqubo zokucoca laserkudala zisetyenziswa kushishino lwezophapho.Umphezulu wenqwelo-moya kufuneka upeyintwe kwakhona emva kwexesha elithile, kodwa ipeyinti endala kufuneka isuswe ngokupheleleyo phambi kokupeyintwa.Indlela yesiqhelo yokususa ipeyinti yomatshini kulula ukwenza umonakalo kumphezulu wentsimbi wenqwelomoya, ozisa iingozi ezifihlakeleyo kwinqwelomoya ekhuselekileyo.Ukusebenzisa iinkqubo ezininzi zokucoca i-laser, ipeyinti inokususwa ngokupheleleyo kwi-A320 Airbus phakathi kweentsuku ezimbini ngaphandle kokonakalisa umgangatho wesinyithi.

Umgaqo womzimba wokucocwa kwelaser ekucoceni umphezulu wenqwelomoya:

1. I-beam ekhutshwe yi-laser ifunnwe ngumaleko ongcolisekileyo phezu komhlaba ukuba uphathwe.
2. Ukufunxwa kwamandla amakhulu kubumba i-plasma ekhula ngokukhawuleza (i-ionized kakhulu igesi engazinzanga), eyenza i-wave shock wave.
3. I-wave shock yaphula izinto ezingcolileyo zibe ngamaqhekeza kwaye iyanqatshwa.
4. Ububanzi be-pulse light kufuneka bube bufutshane ngokwaneleyo ukuthintela ukwanda kobushushu obunokonakalisa umphezulu onyangwayo.
5. Iimvavanyo zibonisa ukuba xa kukho i-oxide kwindawo yesinyithi, i-plasma yenziwa kwindawo yesinyithi.

Imifuniselo ye-laser depeinting (ukucocwa kwelaser) kwizikhumba zenqwelomoya zenziwa kwi-laser fluences ye-2–6 J/cmexp.Emva kovavanyo lokuhlalutya kwe-SEM kunye ne-EDS, iiparamitha zenkqubo yokususa ipeyinti ye-laser zi-5 J/cmex.Ukhuseleko lokubhabha lwenqwelomoya lubaluleke kakhulu, kwaye akukho lahleko yengozi ivumelekileyo.Ke ngoko, ukuba itekhnoloji yokususa ipeyinti ye-laser iya kusetyenziswa ngokubanzi kugcino lwenqwelomoya, ukucocwa okungonakalisi kwenqwelomoya kufuneka kufezekiswe.

Ngaphantsi kweemeko ezahlukeneyo zokuxinaniswa kwamandla e-laser, ukungqubana kunye nokunxiba iipropathi zemingxuma ye-rivet yolusu lwenqwelomoya emva kokucocwa kwaphononongwa yinkqubo yokucoca i-laser, kwaye ukungqubana kunye nokunxiba iipropathi zezinye iindawo eluswini zavavanywa.Ukuthelekiswa kwenziwa kunye neesampuli emva kokugaya oomatshini kunye nokucoca i-laser.Iziphumo zibonise ukuba ukucocwa kwe-laser akuzange kunciphise ukungqubuzana kunye nokugqoka iipropathi zaso naliphi na icandelo eliphezu kwesikhumba senqwelomoya.

Ukuxinezeleka okushiyekileyo, ukuqina kwe-microhardness kunye nokusebenza kwe-corrosion ye-aircraft surface isikhumba emva kokucocwa kwe-laser kwavavanywa.Xa kuthelekiswa nokusila ngomatshini kunye nokucoca i-laser, iziphumo zibonisa ukuba ukucocwa kwe-laser akunciphisi i-microhardness kunye nokumelana nokugqwala kwe-aircraft surface isikhumba.Nangona kunjalo, emva kokucocwa kwe-laser, umphezulu wolusu lwenqwelomoya uya kuvelisa i-deformation yeplastiki, eyingxaki efuna ingqalelo ekhethekileyo xa usebenzisa itekhnoloji yokucoca i-laser ukunyanga umphezulu wolusu lwenqwelomoya.

Ngexesha lokugcinwa kwenqwelomoya.Ipeyinti kumphezulu wenqwelo-moya kufuneka isuswe, kwaye umphezulu wolusu lwenqwelomoya kufuneka uhlolwe ukuze kubonwe iziphene ezidlekayo kunye neentanda zokudinwa ukuze kuphetshwe iingozi zokubhabha.Ngoko ke, kwinkqubo yokususa ngokucophelela ipeyinti ebusweni besikhumba senqwelomoya, kuyimfuneko ukuhlawula ingqalelo ekhethekileyo ukuba inkqubo yokususa ipeyinti kufuneka iqinisekise ukuba i-substrate ayonakaliswa.

Iinkqubo zokususa ipeyinti yemveli ziquka ukucoca ngoomatshini, ukucocwa kwe-ultrasonic, kunye nokucoca iikhemikhali.Nangona obu bugcisa bokucoca bungasentla bubuchwephesha obuqolileyo bokucoca, kusekho ukusilela okuninzi.Ngokomzekelo, indlela yokucoca i-mechanical grinding ilula kakhulu ukwenza umonakalo kwizinto ezisisiseko, indlela yokucoca iikhemikhali iya kungcolisa indalo, kwaye indlela yokucoca i-ultrasonic inqunyelwe ngobukhulu bomsebenzi, kwaye akulula. ukucoca iindawo ezinobungakanani obukhulu.

Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lwetekhnoloji yelaser, itekhnoloji yokucoca i-laser iye yaba yitekhnoloji yokucoca ezenzekelayo, ecacileyo, kunye nexabiso eliphantsi.Itekhnoloji yokucoca i-laser isetyenziswe ngokubanzi kwipeyinti kunye nokususwa komhlwa, ukucocwa kobunjwa bamathaya, ukukhuselwa kwezinto zenkcubeko, ukucocwa kwenyukliya, njl.

Ukuba ufuna ukufunda ngakumbi malunga nokucoca i-laser, okanye ufuna ukukuthengela umatshini wokucoca i-laser, nceda ushiye umyalezo kwiwebhusayithi yethu kwaye usithumelele i-imeyile ngqo!
