Polycrystalline tuag muaj qhov zoo ntawm kev hnav tsis kam, kev ua haujlwm ntev, tus nqi qis, thiab lwm yam., thiab nws daim ntawv thov nyob rau hauv cov khoom siv hlau yog txuas ntxiv mus. Txawm li cas los xij, qhov laj thawj tseem ceeb vim li cas feem ntau cov pwm polycrystalline tuaj yeem tsis tuaj yeem ua tiav pwm yog tias cov kab hluav taws xob ntawm cov xaim rub tawm yuav tshwm sim loj thiab me, thiab txoj kab uas hla ntawm cov hlau tsis yooj yim los tswj.
Hauv cov txheej txheem kev kos duab ntawm cov hlau, cov txheej txheem uas cuam tshuam rau kev pabcuam lub neej ntawm kev tuag yog qhov tseem ceeb: qhov kev txiav txim ntawm qhov rov qab nro P, compression tus nqi ntawm qhov dhau, lubricant thiab qhov zoo ntawm cov hlau.
Cov yam ntxwv cuam tshuam rau tensile kev nyuaj siab
1. Rov qab nro
Qhov rov qab nro yuav ua rau kom lub zog rub, uas tsis haum rau cov txheej txheem ntawm kev kos duab. Txawm li cas los xij, qhov rov qab nro tuaj yeem pom tseeb txo qhov kev ntxhov siab zoo ntawm phab ntsa tuag, uas yog qhov zoo rau cov roj nplua nyeem nkag mus rau thaj tsam deformation thiab tuaj yeem txo qhov kev sib txhuam ntawm cov hlau thiab phab ntsa tuag rau qee qhov, txo qhov tuag qhov hnav, thiab ncua lub neej kev pab cuam ntawm cov tuag. Tau kawg, ntau dhau ntawm kev kos duab yuav ua rau muaj kev ntxhov siab ntau dhau, ua rau muaj qhov sib txawv ntawm qhov sib txawv xws li hlau thinning lossis hlau tawg. Yog li ntawd, qhov tsim nyog txuas ntxiv coefficient yuav tsum tau siv rau hauv kev faib pwm, kom cov hlau muaj peev xwm tswj tau tus nqi zawv zawg ntawm lub nruas thiab zam qhov tsis zoo zawv zawg tshwm sim.
Lub tensile quab yuam ntawm cov hlau nyob rau hauv lub qhov tuag tuag yog: qhov zoo siab, kev sib txhuam quab yuam, rub quab yuam thiab thim rov qab nro ntawm cov phab ntsa tuag Raws li qhov sib npaug ntawm cov quab yuam thaum kos cov hlau thiab cov txiaj ntsig ntawm cov khoom siv hlau, Kev faib tawm ntawm tensile kev nyuaj siab ntawm cov hlau thiab compressive kev ntxhov siab ntawm phab ntsa tuag tuaj yeem txo qhov kev ntxhov siab ntawm qhov nkag ntawm cov hlau tuag, thiab pab cov roj nplua nyeem nkag mus rau qhov chaw ua haujlwm, txo qhov kev sib txhuam ntawm cov hlau thiab phab ntsa tuag. , thiab qeeb lub nplhaib aging puas thiab rupture ntawm cov tuag. Txawm li cas los xij, qhov loj heev rov qab nro yuav ua rau muaj kev ntxhov siab ntawm cov hlau, uas yog ib qho yooj yim ua rau cov xaim me me los yog tawg. Thaum lwm yam kev mob tensile tsis hloov, qhov ntau dua qhov kev ntxhov siab ntawm cov pwm phab ntsa, qhov kev sib txhuam ntau dua, thiab qhov hnyav dua qhov hnav.
2. Elongation coefficient
Thaum lwm cov hlau kos duab tsis hloov pauv, ua kom lub elongation coefficient yuav ua rau ob qho tib si tensile kev nyuaj siab thiab tuag phab ntsa zoo siab. Thaum lub tensile kev nyuaj siab mus txog los yog mus txog qhov txwv tsis pub dhau ntawm cov xaim ntawm qhov hluav taws xob ntawm cov hlau tuag, qhov tsis ruaj khov stretching yuav tshwm sim, ua rau cov hlau nyias nyias los yog tawg. Yog li ntawd, qhov elongation coefficient ntawm txhua qhov hla yuav tsum tau txiav txim siab raws li qhov sib txawv. Feem ntau hais lus, txhawm rau kom ntseeg tau qhov loj thiab qhov zoo ntawm cov hlau, lub elongation coefficient ntawm qhov kawg stretch yuav tsum qis dua qhov dhau los.
3. Kev sib txhuam coefficient
Qhov no yog qhov tseem ceeb tshaj plaws hauv kev kos duab hlau.Tam sim no, feem ntau polycrystalline tuag yuav tsum tsuas yog siv los ua tus choj tuag, feem ntau yog vim qhov kev ua haujlwm polishing ntawm polycrystalline tuag tsis zoo, uas muaj kev sib txhuam loj, thiab kev sib txhuam coefficient ntawm qhov tuag qhov yog qhov sib txawv, uas muaj feem xyuam rau cov khoom siv, lub xeev nto, dhau cov duab thiab nws qhov chaw tiav. Nws kuj tseem muaj feem xyuam rau ntau yam xws li cov khoom siv ntawm cov hlau, lub xeev ntawm qhov chaw, qhov kub thiab txias, thiab qhov zoo ntawm cov roj nplua nyeem vim qhov kev txwv ntawm lub hom phiaj, txawm hais tias qee yam tsis tuaj yeem hloov pauv, peb tseem tuaj yeem txo qis. kev sib txhuam coefficient los ntawm kev txhim kho cov duab kos. Piv txwv li, hauv kev tsim cov tooj liab hlau, koj tuaj yeem siv cov pa oxygen tsis muaj tooj liab zoo thiab cov roj nplua nyeem, tswj cov duab nrawm, thiab ntsuas kub, thiab kho cov txheej txheem kos duab.
Nyob rau hauv luv luv, peb yuav tsum tau them sai sai rau qhov hnav qhov chaw ntawm lub kos duab tuag thaum lub sij hawm siv lub tshuab nqus tsev thiab hloov lawv nyob rau hauv lub sij hawm.
