Cov Khoom Kho Mob PVD txheej tshuab

PVD (lub cev vapor deposition) Txheej hlau yog cov khoom siv tseem ceeb saum teb ntawm cov khoom kho mob.

Lawv muab kev ua siab siab - Kev ua tiav txheej txheem rau kev kho mob siab rau biocompatibility, durability, ua haujlwm tsis muaj menyuam, ua haujlwm thiab zoo nkauj.

Daim Ntawv Thov:

Nqus plua plav TI / PT zaj duab xis nyob rau saum npoo ntawm cov khoom siv kho mob;

Zoo nkauj zoo txhim kho

Siab Hardness thiab Hnav Kuj:

Txhim kho qhov saum npoo tawv tawv ntawm qhov ntsuas, txhim kho kev coj ua tau, txuas ntxiv lub neej kev pabcuam thiab muaj cov ntse.

Tsawg coefficient ntawm kev sib txhuam:

Cov txheej muaj qhov chaw du thiab ib qho qis coefficient ntawm kev sib txhuam, uas txo qhov kev pheej hmoo ntawm kev ua haujlwm, thiab kev ua haujlwm phais mob siab (xws li cov pob qij txha).

Zoo tshaj plaws corrosion:

Cov txheej yog ntom thiab kev ruaj khov ruaj khov, uas muaj peev xwm cais tawm ntawm cov hlau ions, thiab muaj kev nyab xeeb} {}}} siv ntawm lub cuab yeej.

Siab Purity thiab Huv Huv

Tag nrho cov txheej txheem txheej txheej yog nqa tawm hauv lub tshuab nqus tsev siab, uas tiv thaiv cov kuab paug atmospher, hmoov av) los ntawm kev sib xyaw thiab ua kom muaj kev huv ntawm cov txheej.

Cov txheej muaj ntom ntom, tsis {{0} porous qauv thiab qhov nyuaj rau cov kab mob kom muaj kev xaiv tsa tsis muaj zog.

Zoo heev Tshuaj Muaj Zog

Cov khoom txheej txheej tau ruaj khov nyob rau hauv ib puag ncig physiological, tsis yooj yim rau decompe lossis tso tawm cov quav yeeb yam zoo, thiab muaj kev nyab xeeb heev rau kev cog lus ntev.

Orceated Txheej Txheej Thickness

Cov txheej txheej txheej tuab feem ntau yog nyob rau hauv micron lossis txawm tias muaj ntau yam kev ua tau zoo thiab tswj tau cov khoom siv (uas yog qhov tseem ceeb rau cov twj paj nruag kev ntsuas thiab kev cog hniav)

Txhim kho qhov kev ua tau zoo thiab lub neej ntawm cov khoom siv kho mob

Los ntawm kev txhim kho cov hnav tsis kam, corrosion tsis kam, thiab txo qis kev hnav, passivation tsis ua hauj lwm thiab kho cov nqi.

 

Xyuas kom muaj kev nyab xeeb

Cov txheej ntawm biocompe kom ntseeg tau tias kev tiv thaiv kev nyab xeeb thiab kev sib cuag.

Ntom, tsis - Txoj kab txuas tau yooj yim rau kev ua kom tsis taus kab mob kom huv si, txo txoj kev pheej hmoo kis tau.

Corrosion Kuj txwv tsis pub tiv thaiv cov hlau ion kev sib cais, zam kev muaj kuab lom lossis kev ua xua.

 

Txhim kho kev kho mob ua tau zoo thiab ua haujlwm zoo

Cov khoom siv ntse thiab cov khoom siv tsawg {- kev sib txhuam kom cov kws kho mob kom muaj kev phais cov txiaj ntsig zoo thiab txhim kho kev phais mob.

 

Txhim kho cov khoom sib tw thiab ntxiv tus nqi

Kev ua tau zoo, kev ntseeg siab, thiab kev kho mob nto zoo nkauj yog cov khoom siv khomob tseem ceeb, txhim kho hom kev khomob thiab kev ua lag luam kev sib tw.

Cov Khoom Kho Mob PVD txheej tshuab yog ib qho tseem ceeb ntawm kev tsim khoom siab high {{0} {{1} {1} {1} {} Kev ruaj khov kho cov khoom siv kho mob.

Nws tso nyiaj ultra - nyias, muaj kev tiv thaiv kev ua haujlwm, muab cov khoom siv kho mob yooj yim, npaj kho kom huv si, kev tiv thaiv kev nyab xeeb thiab kev tiv thaiv ib puag ncig zoo nkauj tshaj plaws yuav tsum tau.
