Nquag Laser txiav tej yam thiab lawv cov tswv yim tiv thaiv
May 01, 2025| Laser txiav, thaum muaj ntau yam tsis xws luag vim yog cov khoom siv thiams, lossis cov tswv yim los ntawm kev tshawb fawb thiab kev coj ua:
{{01. kub-cuam tshuam-cuam tshuam nrog (hub) thiab thermal distortion
- Cov lus piav qhia tsis zoo: High-Zog Laser Beams ua cua sov (e {} .
- Cov tswv yim tiv thaiv:
- hybrid cov txheej txheem xaiv: Siv abrasive waterjet (awj) Kev txiav tawm tsam tsawg kawg, raws li AWJ zam dhau los ntawm kev txiav txias .
- Kev Ntsuas Optimization: Txo cov hwj huam laser lossis nce kev txiav ceev kom txo qis kev ua kom sov li ntawm cov cua sov)}}}
- Pab cov kev hloov kho roj teeb: Txhim kho cov pa oxygen lossis nitrogen siab rau kev hloov kho hluav taws xob kom haum rau 055 MPa txo saum npoo av los ntawm 23%.

{{02. nto rougness thiab oxidation
- Cov lus piav qhia tsis zoo: tsis sib xws melting lossis oxidation thaum txiav ua kom nruj thiab ua haujlwm oxide {1} {{{{}
- Cov tswv yim tiv thaiv:
- Cov kev tswj hwm zoo nkauj tswj: Siv cov lus teb saum npoo av (RSM) los ua qauv sib cuam tshuam nrog 1 {{}}} zoo li daim iav zoo li ua tiav).
- tom qab ua: annealing lossis tshuab polishing tuaj yeem ua kom du somfaces thiab txo qhov kev nqus tau, ib qho kev haum, cov tswv yim tsim kom muaj xim hlau {}}

3. microcacks thiab porosity
- Cov lus piav qhia sai sai: cua txias heev nyob rau hauv cov ntaub ntawv zoo li superalloys (e {}}
- Cov tswv yim tiv thaiv:
- Kev Ua Ntej Tom Qab Tshav Kub **: Kev Ua Si Ncaj Ncees (DA) ntawm GH4099 SuperSally Enhanced Tshaj Tawm Lub Zog thiab Txo Intergranular Slateures.
- Laser Parameter lub zog: kho lub zog ntom ntom (lub zog sib piv (ceev kev ntsuas) kom ntseeg tau tias tsis muaj kev soj ntsuam pom metomalies, ua kom haum rau kev hloov kho metomalies {}}

4.} Qhov seem tsis muaj tseeb
- Cov lus piav qhia tsis zoo: Thermal expansion lossis nqaj misalignment tseem tuaj yeem ua rau kev sib txawv ntawm cov qauv tsim qauv, xws li Kerf dav inconfies.
- Cov tswv yim tiv thaiv:
- Kev tshuaj xyuas lub sijhawm tiag tiag: tso cov khoom siv cov duab uas muaj kev soj ntsuam zoo li cas.
- Nqaj tswj hwm zoo: siv deformable tsom iav lossis cov iav nyiaj them theem qis kom tsawg dua X-. 04, txhim kho precision.

{{0 {}} slag adyionion thiab txheej txheej txheej
- Cov ntaub ntawv piav qhia: residual cov khoom siv allived rov ua dua tshiab, tsim cov npoo, tshwj xeeb hauv kev txiav txim siab ntawm {}}
- Cov tswv yim tiv thaiv:
- ** Pab roj ua kom zoo **: Ntau dua-siab nitrogen zoo {}} molta roughod deb los ntawm 300 mpa mpa mpa cia {}}
- cov khoom siv tshwj xeeb tshwj xeeb: rau cov ntaub ntawv tshwj xeeb: rau cov ntaub ntawv muaj kev cuam tshuam (e {}, siv pulsed}
