Lus
Cov kab nrib pleb hauv laser cladding feem ntau yog tshwm sim los ntawm kev ntxhov siab thermal, cua txias sai, thiab cov khoom siv tsis zoo. Kev tiv thaiv muaj xws li optimizing txheej txheem tsis, preheating, thiab xaiv cov hmoov haum. Dej chiller tsis ua haujlwm tuaj yeem ua rau overheating thiab nce kev ntxhov siab, ua kom ntseeg tau qhov txias txias tseem ceeb rau kev tiv thaiv kev tawg.
Kev tsim cov Crack yog ib qho kev sib tw hauv cov txheej txheem laser cladding, feem ntau cuam tshuam rau qhov zoo thiab ruaj khov ntawm txheej clad. Kev nkag siab txog cov hauv paus ntsiab lus thiab kev siv cov kev tiv thaiv zoo yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo. Tsis tas li ntawd, kev tswj xyuas kom zoo ntawm lub tshuab ua dej chiller yog qhov tseem ceeb, vim tias qhov tsis ua haujlwm txias tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tawg.
Feem ntau ua rau tawg hauv Laser Cladding
1. Thermal Stress: Ib qho ntawm cov laj thawj tseem ceeb ntawm kev tawg yog thermal stress uas tshwm sim los ntawm kev tsis sib haum xeeb hauv cov coefficient ntawm thermal expansion (CTE) ntawm cov khoom siv hauv paus thiab txheej cladding. Thaum lub caij txias, kev ntxhov siab ntau ntxiv ntawm qhov sib cuam tshuam, ua rau muaj qhov tshwm sim ntawm cov kab nrib pleb.
2. Ceev ceev: Yog tias qhov txias txias yog ceev heev, qhov kev ntxhov siab nyob hauv cov khoom tsis tuaj yeem tso tawm tau zoo, ua rau tawg tsim, tshwj xeeb tshaj yog nyob rau hauv high-hardness los yog brittle cov ntaub ntawv.
3. Cov Khoom Siv Khoom: Cov khoom tawg yuav nce ntxiv thaum siv cov substrates nrog cov tawv tawv (xws li, quenched los yog carburized / nitrided cov ntaub ntawv) los yog cov hmoov uas muaj zog heev hardness los yog tsis zoo compatibility. Substrates nrog qaug zog khaubncaws sab nraud povtseg los yog inconsistent nto zoo kuj yuav ua rau kom tawg.
Kev Tiv Thaiv Kev Tiv Thaiv
1. Optimizing Process Parameters: Ua tib zoo kho lub zog laser, scanning ceev, thiab hmoov pub tus nqi pab tswj cov dej kub hauv pas dej ua ke thiab qhov txias txias, txo cov thermal gradients thiab kev pheej hmoo ntawm kev tawg.
2. Preheating thiab tswj cov cua txias: Preheating cov khoom siv hauv paus thiab siv qeeb, tswj cov cua txias tom qab cladding tuaj yeem pab txo qis kev ntxhov siab, txo qis kev txhim kho tawg.
3. Xaiv cov khoom siv hmoov zoo: Xaiv cov hmoov uas phim cov khoom siv hauv cov khoom siv thermal expansion thiab hardness yog qhov tseem ceeb. Tsis txhob hnyav hnyav lossis thermal incompatibility txo cov kev ntxhov siab sab hauv thiab tawg tsim.
Kev cuam tshuam ntawm Chiller Failures ntawm Crack Tsim
Cov dej chiller ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas thermal ntawm cov khoom siv laser cladding. Yog tias cov dej chiller tsis ua haujlwm , nws tuaj yeem ua rau overheating ntawm lub laser los yog cov khoom tseem ceeb, cuam tshuam cov txheej txheem kev ruaj ntseg. Overheating tuaj yeem hloov pauv cov dej hauv pas dej ua ke thiab ua rau muaj kev ntxhov siab ntau ntxiv hauv cov khoom, ncaj qha ua rau tawg tsim. Ua kom ntseeg tau qhov kev ua tau zoo ntawm chiller yog qhov tseem ceeb rau kev tswj hwm cladding zoo thiab tiv thaiv kev ua haujlwm tsis zoo.
Xaus
Cov kab nrib pleb hauv laser cladding tuaj yeem txo qis los ntawm kev tswj cov kev ntxhov siab thermal, xaiv cov ntaub ntawv tsim nyog, thiab tswj cov cua txias kom ruaj khov. Ib qho dej chiller txhim khu kev qha yog ib qho tseem ceeb ntawm cov kab ke, pab kom tswj tau qhov kub thiab txias thiab cov cuab yeej siv tau ntev.
