Khoom Description
Thoob ntiaj teb, muaj qee qhov kev pom zoo thiab qhov sib txawv ntawm cov qauv ntsuas kev tiv thaiv corrosion rautitanium hlaucov ntaub ntawv.
Hais txog kev pom zoo:
1. Kev nkag siab ntawm cov txheej txheem corrosion thiab qhov tshwm sim zoo ib yam, xws li tag nrho corrosion, pitting corrosion, crevice corrosion, thiab lwm yam.
2. Ob qho tib si tseem ceeb heev rau kev ntsuas kev tiv thaiv corrosion los ntawm kev simulating qhov chaw siv tiag tiag kom ntseeg tau tias qhov kev siv tau zoo ntawm cov txiaj ntsig kev xeem.
3. Qee yam kev sim thiab cov txheej txheem, xws li kev kuaj electrochemical, kuaj ntsev ntsev, thiab lwm yam, muaj qee yam zoo sib xws hauv txoj cai thiab kev ua haujlwm.
Hais txog qhov sib txawv
1. Ntau lub teb chaws thiab cheeb tsam tej zaum yuav tau tsim ntau hom qauv rau nws nyob rau hauv tej thaj chaw tshwj xeeb raws li lawv tus kheej cov yam ntxwv ntawm industrial thiab daim ntawv thov xav tau kev pab. Piv txwv li, cov qauv hauv kev lag luam aerospace tej zaum yuav muaj kev txwv nruj dua rau lub zog thiab kev tiv thaiv rau qhov chaw huab cua, thaum kev kho mob tsom ntau dua rau biocompatibility thiab kev ruaj ntseg mus sij hawm ntev.
2. Cov ntsiab lus ntawm qhov kev xeem yuav txawv. Piv txwv li, qhov concentration, qhov kub thiab txias, txoj kev tshuaj tsuag thiab lwm yam kev ntsuas ntawm cov ntsev ntsev hauv cov tshuaj tsuag ntsev yuav txawv nrog cov qauv sib txawv.
3. Cov kev ntsuam xyuas thiab kev txiav txim rau cov txiaj ntsig kev xeem kuj yuav txawv. Qee cov qauv yuav tsom mus rau ntau qhov kev txheeb xyuas ntawm tus nqi corrosion, thaum lwm tus them ntau xim rau corrosion morphology thiab qib ntawm kev cuam tshuam ntawm kev ua haujlwm.
Cov hauv qab no yog qee qhov feem ntau siv cov qauv ntsuas kev tiv thaiv corrosion rau titanium hlau:
1. GB/T 16545-1996 "Corrosion ntawm hlau thiab alloys - Tshem tawm cov khoom corrosion los ntawm corrosion specimens"
2. GB/T 17898-1999 "Stress Corrosion Test Method for Stainless Steel in Boiling Magnesium Chloride Solution"
3. ASTM G3-14 (2020) "Txoj Cai Ua Raws Cai rau Cov Lus Cog Tseg Siv rau Kev Ntsuas Hluav Taws Xob hauv Kev Ntsuas Corrosion"
4. ASTM G61-86 (2019) Standard Test Method for Conducting Cyclic Potentiometric Polarization Measures for Localized Corrosion Susceptibility of Iron -, Nickel-, or Cobalt-Based Alloys express
5. ISO 15156-1: 2015 Petroleum thiab natural gas industries - Cov ntaub ntawv siv rau hauv H2S uas muaj ib puag ncig hauv kev tsim roj thiab roj - Ntu 1: Cov ntsiab cai dav dav rau xaiv cov khoom siv tiv thaiv tawg
TS EN ISO 9227: 2017 Kev ntsuam xyuas corrosion hauv cov cua tshuab cua - Kev sim ntsev tsuag
