Kev sib tham ntawm anodizing thev naus laus zis rau kev txhim kho cov khoom muag tsis kam

I. Txheej txheem cej luam ntawm anodizing technology

Anodizing yog qhov kev kho tshuab saum npoo uas tsim cov yeeb yaj kiab oxide ntawm cov hlau saum npoo av los ntawm cov txheej txheem electrochemical. Nws yog feem ntau siv rau txhuas thiab nws cov alloys. Cov thev naus laus zis no suav nrog DC lossis AC Voltage rau cov electrolyte, tsim cov tshuaj tiv thaiv oxidation ntawm cov hlau nto, sib sau ua ib tug ntom, tawv txhuas oxide zaj duab xis. Cov lus qhia zaj duab xis no ruaj khov rau lub hauv paus hlau, nce qhov chaw saum npoo hardness thiab zoo txhim kho nws cov coj tsis kam.

Tus Anodic oxide zaj duab xis muaj cov qauv sib dhos. Qhov no cim micromorology tshwj xeeb tshaj plaws muab cov hauv paus zoo heev rau kev sib khi tom qab lossis ua haujlwm zoo. Ua raws li hom electrolyte thiab ua cov haujlwm hauv electrolyte, anodizing tuaj yeem faib ua ntau cov txheej txheem, suav nrog cov sulfuric acid anodizing, thiab oxalic acid anodizing. Cov yeeb yaj kiab oxide tsim los ntawm txhua tus txheej txheem sib txawv hauv thickness, hardness, thiab porosity, uas nyob rau hauv lem cuam tshuam rau cov khoom lag luam tsis kam ntawm cov khoom kawg.

Ii. Kev siv tshuab ntawm anodizing rau kev txhim kho cov hnav tsis kam

1. Nce saum tawv tawv

Thawj qhov ua piv txwv ntawm cov yeeb yaj kiab anodized yog txhuas oxide (al₂o₃), uas yog qhov nyuaj dua li cov txheej txheem txhuas. Lub vickers hardness ntawm dog dig txhuas yog kwv yees li 100 hv. Tom qab anodizing, lub wardness nto tuaj yeem ncav cuag 300-500 hv, thiab harding anodizing tuaj yeem txawm ncav cuag li 1500 hv. Qhov no tseem ceeb nce hauv hardness ncaj qha ncaj qha rau cov khoom siv tiv thaiv kev sib txhuam thiab hnav.

2. Oxide Zaj Duab Xis Cov Qauv Txheej Txheem

Anodic Oxide cov yeeb yaj kiab muaj qhov tshwj xeeb ob - teeb thaiv txheej txheem kwv yees li 0.21} μm tuab, nyob uas nyob ib sab mus rau substrate; Thiab ib txheej txheej sab nraud uas muaj qhov hws tau npaj hauv cov qauv honeycomb. Tus qauv no tsis tsuas yog ua kom muaj kev nyab xeeb rau cov yeeb yaj kiab thiab cov txiaj ntsig zoo, tab sis kuj tso cai rau cov nyhuv rau tus kheej, tab sis kuj tso cai rau kev sib txhuam thiab txo cov coefficient ntawm kev sib txhuam.
