Titanium Disc

Alloy Hom:

Ze ntawm - hom titanium alloy

Nominal muaj pes tsawg leeg: Ti-6Al-2Sn-4Zr-2Mo (Ti6242)

-stabilizer: Aluminium (Al)

Cov khoom nruab nrab: Tin (Sn), Zirconium (Zr)

Isomorphic -stabilizer: Molybdenum (Mo)

Eutectoid -stabilizer: Silicon (Si)

Surface Engineering & Bio-Cov ntawv thov

Titanium discs coated nrog nanoscale sol-gel- muab cov txheej (anatase, rutile, zirconia, alumina) tuaj yeem txhim kho biocompatibility.

Cov txheej txheem no tau pom tias ua kom cov cim qhia osteogenic (alkaline phosphatase, pob txha sialoprotein, osteocalcin, osteoprotegerin, osterix, Runx-2) nyob rau hauv tib neeg mesenchymal qia hlwb piv rau conventionally machined los yog acid-etched titanium.

Qhov no ua rau coated titanium discs tshwj xeeb tshaj yog cog lus rau biomedical implants thiab daim ntawv thov pob txha.

Biofilm Monitoring Technique (Potentiostatic Method)

Kev teeb tsa potentiostatic siv titanium lossis stainless hlau electrodes polarized ntawm lub peev xwm ruaj khov cathodic.

Tom qab ib teev ntawm txhua hnub polarization, cov hluav taws xob sab nraud raug kaw.

Qhov seem tam sim no ntsuas ib ntus (piv txwv li, txhua 10 min) txhua hnub los saib xyuas biofilm kev loj hlob ntawm titanium nto.

Cov txheej txheem no yog siv nyob rau hauv saline los yog marine ib puag ncig.
