Cov kev xav tau ntawm kev ua haujlwm
1. Hardness thiab hnav tsis kam
Cov txheej tiv thaiv yuav tsum muaj siab hardness los tiv thaiv khawb los ntawm cov khoom sab nraud ntawm qhov chawtitanium ntawv ci. Piv txwv li, silicon nitride txheej muaj siab hardness thiab muaj peev xwm tiv thaiv nto ntawm titanium ntawv ci. Nyob rau tib lub sijhawm, kev hnav tsis kam ntawm cov txheej txheej kuj tseem ceeb, vim nws tuaj yeem tuav nws txoj kev tiv thaiv kev ua haujlwm ntev.
Kev ua tau zoo ntawm cov khoom siv sib txawv tuaj yeem raug soj ntsuam los ntawm kev sab laj cov hardness thiab hnav tsis kam ntawm cov ntaub ntawv, los yog xa mus rau cov ntaub ntawv siv tau.
2. Corrosion kuj
Titanium ntawv ci tuaj yeem sib cuag nrog ntau yam corrosive media xws li acids, bases, ntsev, thiab lwm yam hauv ntau qhov chaw. Cov txheej tiv thaiv yuav tsum muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv thaiv cov ntawv titanium los ntawm corrosion. Piv txwv li, polytetrafluoroethylene txheej muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem siv rau hauv ib puag ncig hnyav.
Kev kuaj corrosion tuaj yeem ua tau los ntawm kev nthuav tawm cov khoom siv rau cov xov xwm sib txawv corrosive los soj ntsuam nws cov kev ua haujlwm corrosion.
3. Adhesion
Cov txheej tiv thaiv yuav tsum muaj qhov zoo adhesion rau saum npoo ntawm titanium ntawv ci, txwv tsis pub nws yooj yim tev tawm thiab poob nws cov nyhuv tiv thaiv thaum siv. Qhov zoo ntawm adhesion nyob ntawm yam xws li cov khoom nto ntawm cov khoom siv txheej thiab titanium ntawv ci, txheej txheej txheej txheej txheej, thiab lwm yam.
Kev kuaj adhesion tuaj yeem ua tau, xws li kev kuaj khawb, rub cov ntawv xeem, thiab lwm yam, los ntsuas qhov adhesion ntawm txheej.
4. Kev sib txhuam coefficient
Kev sib txhuam qis coefficient tiv thaiv txheej tuaj yeem txo qhov kev sib txhuam ntawm titanium ntawv ci thiab lwm yam khoom, yog li txo qhov kev pheej hmoo ntawm khawb. Piv txwv li, kev sib txhuam coefficient ntawm polytetrafluoroethylene txheej yog tsawg heev, uas tuaj yeem txo kev sib txhuam kev puas tsuaj.
Cov ntaub ntawv tsim nyog tuaj yeem xaiv los ntawm kev ntsuas qhov sib txhuam coefficient ntawm txheej.
kev thov ib puag ncig
1. Qhov kub thiab txias
Cov ntaub ntawv tiv thaiv sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias. Yog tias cov ntawv ci titanium siv nyob rau hauv qhov kub thiab txias, nws yog ib qho tsim nyog yuav tau xaiv cov ntaub ntawv txheej uas tuaj yeem hloov mus rau qhov kub thiab txias. Piv txwv li, qee cov txheej txheem ceramic tuaj yeem siv rau hauv qhov chaw kub kub, thaum qee cov txheej txheem polymer tuaj yeem muag los yog decompose ntawm qhov kub thiab txias.
Nkag siab txog qhov kub thiab txias rau kev siv titanium ntawv ci thiab xaiv cov ntaub ntawv txheej uas tsim nyog rau qhov kub thiab txias.
2. Chemical ib puag ncig
Xav txog cov tshuaj lom neeg uas titanium ntawv ci tuaj yeem sib cuag nrog, xaiv cov ntaub ntawv txheej nrog cov tshuaj tiv thaiv corrosion. Piv txwv li, yog tias titanium ntawv ci siv nyob rau hauv acidic ib puag ncig, cov ntaub ntawv txheej nrog cov kua qaub zoo yuav tsum tau xaiv.
Ua kev ntsuam xyuas tshuaj sib haum xeeb los ntawm kev nthuav tawm cov khoom txheej rau qhov xav tau tshuaj ib puag ncig thiab saib xyuas nws cov kev hloov pauv.
3. Mechanical stress
Yog tias titanium ntawv ci siv nyob rau hauv kev ntxhov siab, xws li nro, dabtsi yog khoov, thiab lwm yam., cov txheej tiv thaiv yuav tsum muaj qee qhov kev hloov pauv thiab ua haujlwm rau kev ntxhov siab. Txwv tsis pub, lub txheej yuav tawg los yog tev tawm nyob rau hauv cov neeg kho tshuab kev nyuaj siab.
Kev ntsuas kev ua tau zoo xws li tensile thiab dabtsi yog khoov kev sim tuaj yeem ua los ntsuas qhov kev ntxhov siab ntawm cov txheej txheem.
