Nyob rau hauv lub procession ntawm aviation qhov chaw, kev kho mob robots thiab semiconductor kuaj cov khoom, cov khoom raug yuav tsum tau mus txog rau theem txwv ntawm verticality, parallelism thiab flatness yuam kev tsawg dua los yog sib npaug zos rau 0.005mm. Kev ua haujlwm ruaj khov ntawm qhov siab - cov khoom muaj tseeb ncaj qha nyob ntawm qib ntawm kev tshem tawm cov kev ntxhov siab nyob hauv cov khoom. As two core surface finishing processes, artificial aging treatment and cryogenic treatment show significant differences in achieving this goal:
1.Residual stress control
Deep cryogenic kev kho mob:
Los ntawm txias cov khoom mus rau -196℃(kua nitrogen kub), lub sab hauv microstructure ntawm cov khoom yog homogenized thiab cov residual kev nyuaj siab yog txo. Qhov no txo qhov kev pheej hmoo ntawm deformation tshwm sim los ntawm kev ntxhov siab tso tawm thaum lub sij hawm ua tom ntej los yog siv, uas yog ib qho tseem ceeb rau kev tswj cov high-precision geometric tolerances.
kev kho mob aging:
Los ntawm cua sov (xws li 150-200 degree) thiab kev txuag hluav taws xob, cov theem ua kom muaj zog yog precipitated los txhim kho lub zog, tab sis cov txheej txheem kev ntxhov siab yuav tsis raug tshem tawm tag nrho, thiab cov kev ntxhov siab tshiab kuj tseem tuaj yeem qhia tau, ua rau muaj qhov tsis txaus ntseeg tom qab.
2. Cov khoom ruaj khov thiab microstructure
Deep cryogenic kev kho mob:
Kho cov nplej thiab ua kom ruaj khov ntawm microstructure, txo qhov seem ntawm qhov hloov pauv los ntawm qhov kub thiab txias hloov mus rau lub sijhawm, thiab txhim kho qhov ntev - lub sij hawm seem stability.
kev kho mob aging:
Feem ntau yog nyob rau theem nag lossis daus ntxiv. Yog tias qhov kev laus tsis muaj kev tswj hwm (kub, sijhawm) tsis raug tswj xyuas kom zoo, nws yuav ua rau tsis sib xws ntawm cov nag lossis daus theem, cuam tshuam rau homogeneity ntawm cov khoom, thiab tom qab ntawd ua rau lub zos deformation.
3. Kev cuam tshuam ntawm cov khoom siv kho tshuab
Deep cryogenic kev kho mob:
Txhim kho lub hardness thiab hnav tsis kam ntawm cov khoom thaum tuav lub toughness, uas yuav pab txo tau cov cuab yeej siv thaum lub sij hawm tiav thiab txhim kho nto zoo.
kev kho mob aging:
Txhim kho lub zog thiab hardness, tab sis siab dhau heev lawm yuav ua rau kom txiav nyuaj, ua rau lub neej luv luv los yog microcracks deg, uas cuam tshuam qhov tseeb.
4. Ua cov txheej txheem optimization
Deep cryogenic kev kho mob:
Feem ntau nqa tawm tom qab roughing thiab ua ntej ua tiav kom tshem tawm qhov ua ntej- ua kev ntxhov siab thiab xyuas kom meej cov nyiaj ua tiav zoo ib yam; nws tseem tuaj yeem siv los ua kom ruaj khov qhov loj me tom qab ua tiav tiav.
kev kho mob aging:
Nws feem ntau yog siv raws li cov txheej txheem niaj hnub tom qab kev daws teeb meem. Yog tias nws tau ua tiav ua ntej ua tiav, qhov tseeb kawg yuav raug cuam tshuam vim tsis muaj kev tshem tawm cov kev ntxhov siab seem.
5. Nqi thiab txheej txheem complexity
Deep cryogenic kev kho mob:
Nws yuav tsum muaj cov cuab yeej tshwj xeeb ua kua nitrogen, uas yog tus nqi kim thiab nyuaj hauv kev tswj cov txheej txheem, tab sis tsim nyog rau tus nqi siab - ntxiv cov khoom aviation.
kev kho mob aging:
Cov khoom siv yog cov paub tab thiab tus nqi qis, tab sis qhov tseeb lav nyob ntawm kev tswj xyuas nruj, thiab cov nyhuv ntawm cov khoom nrog cov duab nyuaj yuav raug txwv.
Xaus:
Rau ultra-siab precision yuav tsum ntawm 0.005mm, kev kho mob cryogenic muaj ntau qhov zoo hauv kev txo qis kev ntxhov siab thiab txhim kho qhov ruaj khov, tshwj xeeb tshaj yog rau cov khoom siv txhuas tseem ceeb xws li aviation, kho mob thiab neeg hlau. Kev kho kev laus dav dav tsom mus rau kev txhim kho lub zog ntau dua, thiab yuav tsum tau ua ke nrog kev siv tshuab ua kom zoo (xws li ntau yam kev laus + kev ua haujlwm kub qis) lossis siv nrog kev kho cua sov kom coj mus rau hauv tus account ob lub zog thiab qhov tseeb. Hauv kev siv tswv yim, nws yog ib qho tsim nyog yuav tsum ua kom tiav kev xaiv raws li ib feem ntawm cov qauv, cov nqi siv nyiaj thiab lub voj voog ntau lawm.
