1.Laser ho itšeha thekenoloji tšimong ea aerospace ea kopo
Indasteri ea sepakapaka, lisebelisoa tsa ho itšeha ka laser ke: chin alloy, nickel alloy, chromium alloy, alloy aluminium, tšepe e sa hloekang, senotlolo sa acid ea chin, polasetiki le lisebelisoa tse kopaneng.
Ha ho etsoa thepa ea sefofane, khetla ea tšebeliso ea lisebelisoa tse khethehileng tsa tšepe, matla a phahameng, boima bo phahameng, mocheso o phahameng o hanyetsanang le mocheso, mokhoa o tloaelehileng oa ho itšeha o thata ho qeta ho sebetsa, ho itšeha ka laser ke mofuta oa mokhoa o sebetsang oa ho sebetsa, sebelisa bokhoni ba ho seha ka laser, sebopeho sa khekhe ea linotsi, moralo, mapheo, poleiti e emisitsoeng ea mohatla, rotor e kholo ea helikopthara, lebokose la enjine le lelakabe la mollo, jj.
Ho itšeha ka laser hangata ho sebelisoalaser e tsoelang pele ea tlhahiso, empa hape e na le thuso e phahameng ea maqhubu a carbon dioxide pulse laser.Laser seha botebo ho bophara karo-karolelano e phahameng, bakeng sa bao e seng tšepe, botebo ho bophara karo-karolelano ka fihla ho feta 100, tšepe ka fihla ka bang 20;
Ho itšeha ka laserlebelo le phahame, letlapa la alloy ea ho itšeha ke makhetlo a 30 mabapi le mokhoa oa mochini, ho itšeha poleiti ea tšepe ke makhetlo a 20 ka mokhoa oa mochini;
Ho itšeha ka laserboleng bo botle.Ha ho bapisoa le mekhoa ea ho itšeha ea oxy-acetylene le plasma, ho khaola carbon steel ho na le boleng bo botle ka ho fetisisa.Sebaka se amehileng ke mocheso oa laser cutting ke oxy-acetylene feela.
2.Kopo ea theknoloji ea welding ea laser tšimong ea sefofane
Indastering ea lifofane, likarolo tse ngata li cheselitsoe ka beam ea elektronike, hobane welding ea laser ha e hloke ho etsoa ka har'a vacuum, laser welding e sebelisoa ho nkela tšubuhlellano ea electron beam.
Ka nako e telele, kamano pakeng tsa likarolo tsa mohaho oa lifofane e 'nile ea e-ba tšebeliso ea theknoloji ea morao-rao ea riveting, lebaka le ka sehloohong ke hore motsoako oa aluminium o sebelisoang mohahong oa sefofane ke phekolo ea mocheso e matlafalitsoeng ka motsoako oa aluminium (ke hore, matla a phahameng a aluminium alloy), hang ha ho kopana. tjheseletsa, mocheso ho matlafatsa matla a phekolo e tla lahleha, 'me mapetsong a intergranular ho thata ho qoba.
Ho amoheloa ha theknoloji ea welding ea laser ho hlola mathata a joalo mme ho nolofatsa haholo ts'ebetso ea tlhahiso ea sefofane sa sefofane, ho fokotsa boima ba fuselage ka 18% le litšenyehelo ka 21.4% ~ 24.3%.Theknoloji ea li-laser welding ke phetoho ea theknoloji indastering ea tlhahiso ea lifofane.
3.Tšebeliso ea theknoloji ea ho phunya laser sebakeng sa lifofane
Theknoloji ea ho cheka ka laser e sebelisoa indastering ea sepakapaka ho phunya masoba holim'a li-bearings tsa lehakoe, li-blade tsa turbine tse pholileng moea, li-nozzles le li-combustors.Hona joale, ho cheka ka laser ho lekanyelitsoe ho likoti tse pholileng tsa likarolo tsa enjene tse emeng, hobane ho na le mapetsong a microscopic holim'a likoti.
Boithuto ba liteko ba lebone la laser, beam ea elektrone, k'hemistri ea elektronike, ho phunya EDM, ho cheka ka mochini le ho phunya ho phetheloa ka tlhahlobo e felletseng.Ho cheka ka laser ho na le melemo ea phello e ntle, ho feto-fetoha ho matla, ho sebetsa hantle haholo le litšenyehelo tse tlase.
4.Tšebeliso ea theknoloji ea laser holim'a sebaka sa lifofane
Ho roala laser ke theknoloji ea bohlokoa ea ho fetola bokaholimo.Libakeng tsa lifofane, theko ea likarolo tsa lisebelisoa tsa li-aero-engines e phahame, kahoo maemong a mangata ho lokisa likarolo ho na le litšenyehelo tse ngata.
Leha ho le joalo, boleng ba likarolo tse lokisoang bo tlameha ho finyella litlhoko tsa polokeho.Ka mohlala, ha tšenyo e hlaha holim'a lehare la propeller ea sefofane, e tlameha ho lokisoa ka theknoloji e itseng ea ho hloekisa.
Ntle le matla a phahameng le ho hanyetsa mokhathala ho hlokehang ke li-blades tsa propeller, ho hanyetsa ha kutu ka mor'a ho lokisoa ha holim'a metsi ho tlameha ho nkoa hape.Theknoloji ea ho roala laser e ka sebelisoa ho lokisa bokaholimo ba 3D ba lehare la enjene.
5.Tšebeliso ea theknoloji ea ho etsa laser sebakeng sa lifofane
Tšebeliso ea mahlale a ho etsa li-laser ho bofofisi e bonahala ka kotloloho ho hlahisoeng ka kotloloho likarolo tsa sebopeho sa titanium alloy bakeng sa sefofane le tokiso e potlakileng ea likarolo tsa enjine ea sefofane.
Theknoloji ea tlhahiso ea laser e fetohile e 'ngoe ea mahlale a macha a ho etsa lisebelisoa bakeng sa likarolo tse kholo tsa sebopeho sa titanium alloy ea libetsa le lisebelisoa tsa ts'ireletso ea sefofane.Mokhoa o tloaelehileng oa ho etsa lihlahisoa o na le bofokoli ba litšenyehelo tse phahameng, nako e telele ea ho lokisetsa hlobo ea ho etsa hlobo, palo e kholo ea ts'ebetso ea mechine le tekanyo e tlaase ea tšebeliso ea thepa.
