Iindlela ezahlukeneyo zokusika i-Laser ukusika umatshini

Laser ukusika yindlela non-zoqhagamshelwano processing ngamandla aphezulu kunye nolawulo mninzi mninzi. Indawo ye-laser ene-eneji ephezulu yamandla yenziwa emva kokugxila kumqadi we-laser, eneempawu ezininzi xa zisetyenziswa ekusikeni. Kukho iindlela ezine ezahlukeneyo ukusika laser ukuze ukujongana neemeko ezahlukeneyo.

Ukusika kwe-1 

Ukusika okunyibilikisayo kwe-laser, izinto ezinyibilikisiweyo zikhutshwa ngendlela yokuhamba komoya emva kokuba indawo yokusebenza inyibilikile ekuhlaleni. Ngenxa yokuba ukuhanjiswa kwezinto kwenzeka kuphela kwimeko yolwelo, le nkqubo ibizwa ngokuba yi-laser melting cutting.
Umqadi we-laser ococekileyo ococekileyo wokusika irhasi wenza ukuba izinto ezincibilikiweyo zishiye isiki, ngelixa igesi ngokwayo ingabandakanyeki ekusikeni. Ukusika i-Laser ukunyibilika kunokufumana isantya esiphezulu sokusika kunokusika kwegesi. Amandla afunekayo ekwenzeni i-gasification ahlala ephezulu kunamandla afunekayo ukuze anyibilike izinto. Ukusika kwe-laser ukunyibilika, umqadi we-laser ugqityiwe kuphela. Isantya sokusika esona siphezulu sonyuka ngokunyuka kwamandla e-laser, kwaye sinciphise phantse ngokungafaniyo nokunyuka kobunzima beplate kunye nobushushu bokunyibilika kwezinto. Kwimeko yamandla athile e-laser, into ethintelayo luxinzelelo lomoya kwisikwere kunye nokuqhutywa kobushushu bezinto eziphathekayo. Kwizinto zentsimbi kunye neetitanium, ukusika kwe-laser melt kunokufumana ii-notches ze-oxidation. Kwizinto zentsimbi, uxinano lwamandla e-laser luphakathi kwe-104w / cm2 kunye ne-105W / cm2.

Ukusika i-2.Vaporization

Kwinkqubo yokusika i-laser gasification, isantya sobushushu bomhlaba obuphakamileyo obonyukayo ukuya kwiqondo lobushushu obukhawulezayo ngokukhawuleza kangangokuba sinokuthintela ukunyibilika okubangelwa kukuqhutywa kobushushu, ngoko ke ezinye izinto ziphefumla zibe ngumphunga zize zinyamalale, kwaye ezinye izinto zivuthelwa kude emazantsi okusika umthungo ngokuhamba kwegesi ngokuncedisayo njenge-ejecta. Amandla aphezulu e-laser ayadingeka kule meko.

Ukuthintela umphunga wezinto ezivela kukujija kodonga oluqhekeziweyo, ubukhulu bezinto kufuneka bungabi bukhulu kakhulu kunobubanzi be-laser beam. Le nkqubo ke ilungele kuphela izicelo apho ukupheliswa kwezinto ezinyibilikiweyo kufuneka kuthintelwe. Ngapha koko, le nkqubo isetyenziswa kuphela kwicandelo elincinci kakhulu lokusetyenziswa kweealloys zentsimbi.

Inkqubo ayinakusetyenziselwa izinto ezinje ngomthi kunye nezinye iiseramikhi, ezingekho kwimeko yokutyibilika kwaye akunakulindeleka ukuba zivumele umphunga wezinto zokuphinda udibanise. Ukongeza, ezi zinto zihlala zifuna ukufezekiswa okusikiweyo. Ukusika i-laser gasification, i-borim efanelekileyo egxile kuxhomekeke kubukhulu bezinto kunye nomgangatho we-boram. Amandla e-Laser kunye nobushushu bomphunga kunomphumo othile kuphela kwindawo efanelekileyo. Esona santya siphezulu sokusika silingana ngokuchanekileyo kwiqondo lokushisa kwegesi xa ubukhulu beplate buzinzile. Amandla oxineneyo e-laser angaphezulu kwe-108W / cm2 kwaye ixhomekeke kwimathiriyeli, ukusika ubunzulu kunye nokugxila kwindawo. Kwimeko yokuqina kwepleyiti ethile, ucinga ukuba kukho amandla alingeneyo e-laser, isantya sokusika esona siphezulu sikhawulelwe sisantya sejethi yegesi.

3.Ukusika ukophuka okulawulwayo

Kwizinto ezinobunzima ekulula ukuba zonakaliswe bubushushu, isantya esiphezulu kunye nokusika okungalawulekiyo ngokufudumeza umqadi we-laser kubizwa ngokuba kukusika ukwaphuka okulawulwayo. Umxholo ophambili wale nkqubo yokusika yile: i-laser beam ishushu indawo encinci yezinto ezinobunzima, nto leyo ebangela i-gradient enkulu ye-thermal kunye ne-deformation enkulu kule ndawo, ekhokelela ekwenziweni kweentanda kwizinto. Ngethuba nje i-gradient yokufudumeza efanayo igcinwa, umqadi we-laser unokukhokela ukuvelisa iintanda kulo naliphi na icala elifunayo.

4.Oxidation ukunyibilika ukusika (ukusika ilangatye laser)

Ngokubanzi, irhasi egalelwe isetyenziselwa ukunyibilika kunye nokusika. Ukuba kusetyenziswa ioksijini okanye enye igesi esebenzayo endaweni yoko, loo nto iya kutshiswa phantsi kwemitha yelitha ye-laser, kwaye omnye umthombo wobushushu uya kwenziwa ngenxa yempendulo yeekhemikhali enamandla kunye neoksijini ukuqhubela phambili ubushushu, obizwa ngokuba kukunyibilika kwe-oxidation kunye nokusika .

Ngenxa yesi siphumo, ireyithi yokusika yentsimbi enobunzima obufanayo inokuphakama kunaleyo yokusika. Kwelinye icala, umgangatho wokusikwa unokuba mbi ngakumbi kunendlela yokusika. Ngapha koko, iya kuvelisa izilayidi ezibanzi, uburhabaxa obucacileyo, ukwanda kobushushu obuchaphazeleka kwindawo kunye nomgangatho ombi. Ukusika ilangatye nge-Laser akulunganga kwimodeli ezichanekileyo kunye neekona ezibukhali (kukho ingozi yokutsha kweekona ezibukhali). I-lassa mode ingasetyenziselwa ukunciphisa ifuthe lobushushu, kwaye amandla e-laser amisela isantya sokusika. Kwimeko yamandla athile e-laser, into ethintelayo kukubonelelwa kweoksijini kunye nokuqhutywa kobushushu bezinto eziphathekayo.
