Cov teeb meem thiab kev daws teeb meem hauv titanium alloy sib tsoo
Titanium alloys tau muab faib ua peb pawg: titanium alloy, titanium alloy, thiab + titanium alloy. Feem ntau siv titanium alloy specification yog TC4 (Ti-6AI-4}V), uas yog titanium alloy nrog ib + theem qauv. Titanium alloys muaj cov yam ntxwv ntawm lub zog siab, zoo thermal stability, siab kub lub zog, kev ua haujlwm siab, thiab thermal conductivity tsawg. Qhov kub siab dua, qhov hardness ntau dua. Titanium alloy yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws los ua cov txheej txheem. Sib tsoo titanium alloys feem ntau siv 36 # -80# particle loj, uas nyuaj heev rau polish thiab muaj kev sib tsoo tsis zoo.
1. Teeb meem hauv kev sib tsoo
1>Qhov teeb meem ntawm kev sib tsoo ntawm lub log sib tsoo yog qhov hnyav
Thaum lub sij hawm sib tsoo txheej txheem, titanium alloy ntawm qhov chaw ntog tawm thiab ua raws li kev sib tsoo lub log, thiab cov khoom sib tsoo yuav poob nrog cov hmoov nplej ntawm cov khoom sib tsoo thaum lub sij hawm sib tsoo tom ntej, uas ua rau lub log sib tsoo heev.
2>Lub workpiece yog yooj yim rau hlawv, deformation thiab tawg
Vim yog cov yam ntxwv ntawm titanium alloy uas qhov kub thiab txias dua, qhov hardness ntau dua, qhov sib tsoo ntau dua yuav tsum tau, qhov kub ntau dua, thiab cov cua sov xa mus rau qhov chaw ua haujlwm yog qhov nyuaj rau kev tawm, thiab overheating yuav ua rau cov titanium puas. alloy, uas yog ib qho yooj yim ua rau lub workpiece hlawv, deform, thiab txawm tawg.
2. Haum abrasives
Vim tias titanium alloy yog cov hlau tsis muaj hlau, nws yog qhov tsim nyog rau kev sib tsoo nrog silicon carbide (SiC) lossis ntsuab silicon carbide (GreenSiC), lossis superhard pob zeb diamond abrasives (Pob zeb diamond). Ntsuab silicon carbide thiab silicon carbide sib tsoo lub log muaj qhov adhesion tsawg dua, thiab muaj qhov kub thiab tawg tsawg. Yog li ntawd, ntsuab silicon carbide sib tsoo log feem ntau yog siv.
3. Kev daws teeb meem sib tsoo
Yog vim li cas vim li cas lub sib tsoo log yog feem ntau rau kev sib tsoo thaum lub sij hawm sib tsoo txheej txheem ntawm titanium alloy thiab lub workpiece yog nquag mus hlawv, deformation thiab cracking yog vim lub siab sib tsoo kub. Kev sib tsoo kub yuav ua rau cov yas deformation hnyav, uas yuav ua rau lub ntsej muag ntawm lub workpiece puas, thiab cov abrasive thiab hlau yuav ua rau muaj kev sib raug zoo los ntawm lub cev los yog tshuaj adsorption. Qhov kev daws teeb meem tseem ceeb tshaj plaws yog los daws qhov teeb meem kub dissipation. Qhov kev coj ua zoo tshaj plaws yog txhawm rau txhim kho qhov sib tsoo sib piv thiab ua tiav kev tshem tawm ntau dua nrog kev sib tsoo me me li qhov ua tau.
Kev xyaum ua ib txwm ua: qeeb qeeb ntawm kev sib tsoo lub log nrawm yuav txo qhov sib tsoo kub, thiab kev sib tsoo zoo dua yuav ua tiav qhov kev sib hloov ceev; Txawm li cas los xij, nyob rau hauv rooj plaub no, vim qhov qeeb qeeb, kev sib tsoo lub log yuav nrawm dua, ntau lub sijhawm thiab zaus ntawm kev hnav khaub ncaws, kev ua haujlwm qeeb qeeb, uas yuav cuam tshuam rau nws cov nqi ua, thiab tseem muaj qee yam cuam tshuam. ntawm lub dav hlau raug / qhov tseeb ntawm qhov workpiece; yog li ntawd, qhov no tsis yog txoj kev zoo tshaj plaws.
Kev coj ua zoo tshaj plaws: ua tiav cov txiaj ntsig zoo thaum tshav kub kub dissipation nyob rau hauv cov xwm txheej ntawm qhov ceev ceev. Sib tsoo ntawm qhov siab tshaj plaws uas tau tso cai los ntawm kev sib tsoo lub log lossis lub tshuab sib tsoo, thiab siv lub log sib tsoo los yog cov dej sib tsoo los yog cov txheej txheem ua kom ua tau zoo dua cov cua sov dissipation, thiab sim tsis txhob poob qhov kev sib hloov ceev ntawm lub log sib tsoo kom tsis txhob nkim tus nqi ntawm cov khoom siv. sib tsoo log. Yog li ntawd, titanium alloy sib tsoo kua tau los ua. Cov kev cai rau titanium alloy sib tsoo kua, ntxiv rau qhov txias thiab yaug, tseem ceeb dua rau inhibit qhov adhesion thiab tshuaj tiv thaiv ntawm titanium thiab abrasive hais. Nws raug nquahu kom siv cov dej-soluble sib tsoo cov kua dej uas muaj ntau yam khoom siv siab heev.
Titanium alloy sib tsoo kua muaj kev ruaj ntseg zoo heev thiab tiv thaiv xeb. Lub neej ua haujlwm ntev tshaj plaws tuaj yeem tshaj li ob xyoos; nws muaj kev ua haujlwm zoo los tiv thaiv xeb thiab txo kev noj cov kua dej. Nyob rau tib lub sijhawm, titanium alloy sib tsoo cov kua dej tsis muaj cov khoom tsis zoo xws li chlorine, nitrite, phenol, thiab lwm yam. Nws yog ib qho kev sib tsoo ntawm ib puag ncig uas yuav tsis ua rau tawv nqaij thiab tiv thaiv kev noj qab haus huv ntawm tus neeg teb xov tooj. Yog tias koj xav siv lub log sib tsoo uas twb muaj lawm los txhim kho kev ua tau zoo, koj tuaj yeem sim txo qhov nrawm ntawm lub log sib tsoo kom pom tias cov nyhuv ua tiav. Yog tias muaj, nws ua pov thawj tias qhov teeb meem tshwm sim los ntawm kev sib tsoo kub. Koj tuaj yeem pib los ntawm tus mob no thiab saib seb lwm yam xwm txheej yuav tsum raug teeb tsa li cas.
Nyob rau hauv dav dav, nws yog siv lub tshav kub dissipation ntawm lub sib tsoo log, ntxiv rau kev sib koom tes ntawm lwm yam tshav kub dissipation txoj kev, xws li seb lub txiav kua yog zoo sib xws; cia nws muab cov cua sov zoo dua.
