Cov oxide zaj duab xis bonds nruj rau titanium substrate thiab tsis yooj yim detached.

Cov yam ntxwv ntawm cov qauv no ua rau nws ua tau zoo heev.

 

Cov kauj ruam Flow

Lub anodizing ntawm titanium thiab nws cov alloys feem ntau koom nrog ntau kauj ruam. Ua ntej, cov khoom nto yuav tsum tau ntxuav kom tshem tawm cov roj thiab impurities. Qhov no yog ua raws li cov kua qaub los yog tshuaj kho mob kom ua rau lub ntsej muag zoo ib yam. Tom ntej no, lub workpiece yog immersed nyob rau hauv lub electrolyte thiab txuas nrog lub hwj chim qhov chaw rau anodizing. Thaum lub sij hawm cov tshuaj tiv thaiv, tsis xws li voltage, tam sim no, thiab lub sij hawm yuav tsum tau tswj los xyuas kom meej uniform oxide zaj duab xis tsim. Thaum kawg, cov txheej txheem tiav tom qab ntxuav thiab ziab.

 

Xim Tsim Mechanism

·Optical Interference Phenomenon

Txawv oxide zaj duab xis thicknesses ua rau lub teeb cuam tshuam.

·Txawv Thicknesses nthuav tawm txawv xim

Raws li oxide zaj duab xis maj mam thickens, xim hloov.

·Siab xim ruaj khov

Vim tias cov xim pib los ntawm cov qauv oxide zaj duab xis, nws tsis yooj yim faded.

Qhov tshwm sim no muab titanium anodizing zoo nkauj tus nqi.

 

Tej yam cuam tshuam rau cov txheej txheem tshwm sim

Cov nyhuv anodizing yog cuam tshuam los ntawm ntau yam.
