Kev txiav txim siab ntawm cov khoom siv cog qoob loo feem ntau yog nyob ntawm nws cov khoom tsim khoom, txheej txheem kho saum npoo, thiab cov khoom siv biocompatibility thiab txhua yam khoom. Qhov no yog qhov tseem ceeb heev rau kev ua kom muaj kev nyab xeeb ntawm kev phais thiab ntev - lub sijhawm ruaj khov.
1. Cov khoom siv tseem ceeb
Kev kho mob- qib stainless hlau (xws li, SUS304, SUS316L): Siv dav hauv cov cuab yeej phais mob niaj hnub, nws muaj kev tiv thaiv corrosion zoo heev thiab lub zog, haum rau kev ua kom tsis muaj menyuam tsis tu ncua. SUS316L muaj molybdenum, muab kev tiv thaiv zoo rau cov tshuaj chloride ion corrosion thiab ua rau nws tsim nyog rau cov cheeb tsam nyuaj.
Titanium alloy: Qee cov khoom siv siab- kawg yog ua los ntawm titanium alloy, tshwj xeeb tshaj yog haum rau cov neeg mob uas muaj kev fab tshuaj. Nws yog lub teeb yuag, muaj biocompatibility zoo heev, thiab tsis yog -magnetic, yog li nws tsis cuam tshuam nrog kev tshuaj ntsuam xyuas.
Cov txheej tshwj xeeb ntawm cov cuab yeej taub hau: Piv txwv li, cov cuab yeej laum yuav muaj titanium nitride (TiN) los yog pob zeb diamond txheej, txhim kho hnav tsis kam thiab txiav efficiency, thiab txo qis kev puas tsuaj rau cov pob txha.
Cov ntaub ntawv cov ntaub ntawv tuaj yeem raug lees paub los ntawm cov khoom siv los yog cov ntawv ntim khoom. Cov khoom lag luam muaj koob npe yuav qhia meej cov qauv khoom xws li "SUS304" lossis "Ti-6Al-4V".
2. Nto kho cov yam ntxwv qhia
Passivation Treatment: Siab- cov cuab yeej zoo muaj qhov sib xws matte nyiaj saum npoo, tsis muaj khawb los yog xeb, txo qhov kev pheej hmoo ntawm cov hlau ion leaching.
Anodizing/Micro-arc Oxidation: Qee qhov aluminium alloy qhov chaw (xws li cov tes tuav) muaj cov yeeb yaj kiab dub lossis xim xim tom qab kev kho mob no, txhim kho kev hnav thiab rwb thaiv tsev.
Sandblasting thiab Acid Etching (SLA): Txawm hais tias feem ntau yog siv rau kev cog ntoo nws tus kheej, qee cov khoom siv siab - kawg kuj siv cov txheej txheem zoo sib xws rau cov khoom siv clamping los txhim kho kev sib txhuam thiab tiv thaiv - cov khoom plam.
