Lawv feem ntau ua haujlwm hauv kev lag luam xws li aerospace thiab automotive rau hardening kis qhov chaw, cav Cheebtsam, thiab lwm yam kev siv hnyav.
- Nd:YAG Lasers: Nd:YAG (neodymium-doped yttrium aluminium garnet) lasers muaj luv luv wavelength piv rau CO2 lasers, ua rau lawv zoo dua rau ntiav-tob hardening daim ntaub ntawv. Cov lasers no feem ntau siv hauv kev kho mob kev lag luam rau hardening cov cuab yeej phais, kho hniav, thiab lwm yam me me, precision Cheebtsam. Nd: YAG lasers muab cov kab teeb pom kev zoo thiab qhov tseeb, ua rau lawv nrov hauv kev lag luam uas muaj kev tswj xyuas zoo ntawm cov txheej txheem hardening yog qhov tseem ceeb.
- Diode Lasers: Diode lasers tau txais kev muaj koob npe nyob rau hauv thaj chaw ntawm qhov tawv tawv vim lawv cov kev ua haujlwm siab thiab kev ua haujlwm zoo. Cov lasers no siv cov ntaub ntawv semiconductor thiab emit laser teeb nrog ib tug nqaim wavelength ntau yam. Diode lasers feem ntau yog siv rau hardening me me thiab ilv Cheebtsam, xws li cov khoom siv hluav taws xob, cov cuab yeej txiav, thiab pwm nto. Lawv muab cov txiaj ntsig zoo xws li kev cog lus me me, lub teeb pom kev zoo, thiab kev tswj xyuas meej ntawm thaj chaw muaj kev kub ntxhov.
- Solid-State Lasers: Solid-state lasers, uas suav nrog lasers xws li Nd: YAG thiab fiber ntau lasers, kuj tau siv rau saum npoo tawv. Cov lasers no siv cov khoom nce nruab nrab es tsis txhob siv cov roj los yog kua, muab lub zog siab ceev thiab kev tswj xyuas meej ntawm cov nqaj laser. Solid-state lasers yog qhov nyiam rau lawv txoj kev ntseeg siab, kev ua neej ntev, thiab tsim nyog rau cov ntawv thov kev lag luam uas xav tau kev ua haujlwm tas mus li thiab cov khoom siv hluav taws xob siab.
3. Puas yog laser hardening zoo dua nplaim taws?
Laser hardening muaj ntau yam zoo dua li cov txheej txheem nplaim taws-hardening. Ib qho txiaj ntsig tseem ceeb yog tias laser hardening ua rau muaj qhov sib xws thiab sib zog ua kom zoo dua. Lub laser txoj kev tswj kom meej tso cai rau cov cua sov zoo ib yam thoob plaws qhov chaw, txo qhov kev pheej hmoo ntawm distortion los yog tsis sib xws hardening.
Nyob rau hauv sib piv, nplaim taws hardening cia siab rau ib tug torch phau ntawv manipulation, ua rau nws yooj yim mus tsim inconsistencies nyob rau hauv hardened txheej tob thiab zoo. Tsis tas li ntawd, laser hardening tso cai rau kev hloov pauv ntau dua hauv cov txheej txheem hardening, xws li lub peev xwm los tswj qhov tob ntawm cov txheej tawv tawv thiab thaj chaw uas muaj cua sov.
4. Ua li cas hauv laser hardening ua haujlwm?
Internal laser hardening ua hauj lwm los ntawm exposing cov hlau tivthaiv nto rau ib tug high-siv laser beam. Lub laser beam generates tshav kub, uas sai heats saum npoo ntawm cov khoom mus rau nws hardening kub. Qhov no tshwm sim nyob rau hauv tsim ntawm ib tug nyias, hardened txheej nyob rau saum npoo ntawm cov khoom.
Cov txheej txheem hardening yog pab los ntawm cov khoom muaj pes tsawg leeg, nrog rau qee yam hlau, xws li steel, tshwj xeeb tshaj yog haum rau cov txheej txheem vim lawv cov ntsiab lus carbon siab. Lub zog laser yog absorbed los ntawm carbon nyob rau hauv cov khoom, tsim ib tug nyuaj, martensitic qauv ntawm qhov chaw. Cov qauv no muaj zog tiv taus hnav, ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov kev ntxhov siab.
