Yintoni ekufuneka uyazi malunga nokuCocwa kweLaser
I-laser yokuqala yehlabathi yasungulwa ngo-1960 ngusosayensi waseMelika uNjingalwazi uTheodore Harold Mayman esebenzisa uphando lwerubhi kunye nophuhliso, Ukususela ngoko iteknoloji yelaser inceda uluntu ngeendlela ezahlukeneyo.Ukuthandwa kobuchwephesha belaser kwenza uphuhliso olukhawulezayo lwenzululwazi nobuchwepheshe kwiinkalo zonyango lwezonyango, ukwenziwa kwezixhobo, umlinganiselo ochanekileyo kunye nobunjineli bokwenziwa ngokutsha bukhawulezise isantya senkqubela phambili yoluntu.
Ukusetyenziswa kwe-laser kwintsimi yokucoca kuye kwenza impumelelo ebalulekileyo.Xa kuthelekiswa neendlela zokucoca zendabuko ezifana ne-mechanical friction, i-chemical corrosion kunye ne-high-frequency ultrasound yokucoca, ukucocwa kwe-laser kunokuqonda ngokupheleleyo ukusebenza ngokuzenzekelayo kunye nezinye izibonelelo ezifana nokusebenza okuphezulu, ixabiso eliphantsi, ukungcola, akukho monakalo kwizinto ezisisiseko kunye nokulungiswa okuguquguqukayo. umda obanzi wosetyenziso.Ukucocwa kweLaser kuhambelana ngokwenene nombono wohlaza, ukusetyenzwa kokusingqongileyo kwaye yeyona ndlela ithembekileyo nesebenzayo yokucoca.
Imbali yoPhuhliso lweLaser yokuCoca
Ukususela ekuzalweni kombono weteknoloji yokucoca i-laser phakathi kwe-1980, ukucocwa kwe-laser kuye kwahamba kunye nenkqubela phambili ye-laser technology kunye nophuhliso.Ngeminyaka yee-1970, u-J. Asums, isazinzulu e-United States, wabeka phambili ingcamango yokusebenzisa iteknoloji yokucoca i-laser ukucoca umfanekiso oqingqiweyo, i-fresco kunye nezinye izinto zenkcubeko.Kwaye ibonakalisile ngokusebenza ukuba ukucocwa kwelaser kunendima ebalulekileyo ekukhuseleni izinto zenkcubeko.
Amashishini aphambili abandakanyekayo ekuveliseni izixhobo zokucoca i-Laser ziquka i-Adapt Laser kunye ne-Laser Clean All evela e-United States, i-El En Goup esuka e-Italy kunye ne-Rofin yaseJamani, njl njl. Uninzi lwezixhobo zabo zeLaser zinamandla amakhulu kunye nokuphindaphinda okuphindaphindiweyo kweLaser. .Umzekelo, EYAssendel'ft et al.okokuqala kusetyenziswe i-short-wave high pulse energy CO2 laser ngo-1988 ukwenza uvavanyo lokucoca olumanzi, i-pulse ububanzi be-100ns, i-pulse eyodwa yamandla i-300mJ, ngelo xesha kwindawo ehamba phambili yehlabathi.Ukusukela ngo-1998 ukuza kuthi ga ngoku, ukucocwa kwelaser kuye kwaphuhliswa ngokutsiba kunye nemida.R.Rechner et al.wasebenzisa i-laser ukucoca umaleko we-oksidi kumphezulu we-aluminium alloy kwaye waqaphela utshintsho lweentlobo zezinto kunye neziqulatho ngaphambi nasemva kokucoca ngokuskena i-electron microscopy, i-energy dispersive spectrometer, i-infrared spectrum kunye ne-X-ray photoelectron spectroscopy.Abanye abaphengululi baye bafaka i-laser ye-femtosecond ekucoceni nasekugcinweni kwamaxwebhu embali kunye namaxwebhu, kwaye ineenzuzo zokucoca okuphezulu, isiphumo esincinci sokuguqula umbala kwaye akukho monakalo kwimicu.
Namhlanje, ukucocwa kwe-laser kuyanda e-China, kwaye i-MimoWork iqalise uluhlu lwezixhobo eziphezulu zokucoca i-laser eziphathwayo ukuze zikhonze abathengi kwimveliso yesinyithi kwihlabathi jikelele.

Umgaqo wokuCoca iLaser
Ukucocwa kweLaser kukusebenzisa iimpawu zoxinaniso lwamandla aphezulu, ulwalathiso olulawulekayo kunye nokukwazi ukuhlangana kwelaser ukuze amandla okubopha phakathi kwezinto ezingcolisa i-matrix atshatyalaliswe okanye ungcoliseko lube ngumphunga ngokuthe ngqo kwezinye iindlela zokuphelisa ungcoliseko, ukunciphisa amandla okubopha izinto ezingcolisayo kunye ne-matrix, kwaye emva koko ufezekise ukucoca umphezulu we-workpiece.Xa izinto ezingcolisayo kumphezulu we-workpiece zifunxa amandla e-laser, i-gasification yabo ekhawulezayo okanye ukwanda kwe-thermal ngokukhawuleza kuya kunqoba amandla phakathi kwezinto ezingcolileyo kunye ne-substrate surface.Ngenxa yokwanda kwamandla obushushu, i
Yonke inkqubo yokucoca ngelaser inokwahlulwa ngokwezigaba ezine:
1. ukubola kwe-laser gasification,
2. ukuhluthwa kwelaser,
3. Ukwandiswa kwe-thermal yamasuntswana angcolisekileyo,
4. ukungcangcazela komphezulu we-matrix kunye ne-detachment engcolileyo.
Ezinye iingqalelo
Ngokuqinisekileyo, xa usebenzisa iteknoloji yokucoca i-laser, ingqalelo kufuneka ihlawulwe kwinqanaba lokucoca i-laser yento ekufuneka icocwe, kwaye i-laser wavelength efanelekileyo kufuneka ikhethwe, ukuze kufezekiswe isiphumo esihle sokucoca.Ukucocwa kweLaser kunokutshintsha ukwakheka kweenkozo kunye nokuqhelaniswa ne-substrate surface ngaphandle kokonakalisa umphezulu we-substrate, kwaye kunokulawula uburhabaxa be-substrate surface, ukuphucula ukusebenza kwayo okubanzi kwendawo engaphantsi.Umphumo wokucoca uchaphazeleka kakhulu kwiimpawu ze-beam, iiparitha eziphathekayo ze-substrate kunye nezinto ezingcolileyo kunye nomthamo wokufunxa ukungcola kumandla ombane.
