Txheej txheej, yooj yim muab tso, yog txheej txheem ntawm txheej txheej nyias zaj duab xis rau saum npoo ntawm cov khoom. Cov yeeb yaj kiab no tuaj yeem siv los txhim kho cov khoom ua haujlwm (xws li kev tiv thaiv corrosion, hluav taws xob conductivity), kev zoo nkauj, lossis lwm yam tshwj xeeb. Cov txheej txheem tuaj yeem ua tiav los ntawm ntau yam txheej txheem, txhua tus muaj nws tus kheej cov ntawv thov tshwj xeeb thiab qhov zoo.
1. Lub cev Vapor Deposition (PVD)
Lub cev vapor deposition (PVD) yog ib lub tshuab uas siv cov txheej txheem ntawm lub cev los tso cov yeeb yaj kiab nyias ntawm cov ntaub ntawv hauv paus. Nws suav nrog ob txoj hauv kev tseem ceeb: evaporation thiab sputtering. Thaum lub sij hawm evaporation txheej txheem, lub hom phiaj hlau yog rhuab mus rau lub evaporation point, thiab nws cov vapor condenses ntawm lub substrate nto los ua ib tug nyias zaj duab xis. Hauv sputtering, cov khoom siv hluav taws xob siab ua rau lub hom phiaj, ua rau nws cov atoms lossis molecules tshem tawm thiab tso rau ntawm lub substrate. PVD yog siv dav hauv kev tsim cov khoom siv los tiv thaiv kev hnav thiab tiv thaiv corrosion nyuaj, cov yeeb yaj kiab hauv cov khoom siv hluav taws xob, thiab cov txheej txheem zoo nkauj.
2. Tshuaj vapor deposition (CVD)
Chemical vapor deposition (CVD) yog ib lub tshuab uas tso cov khoom siv rau ntawm cov khoom siv los ntawm cov tshuaj lom neeg. Cov txheej txheem no suav nrog kev nthuav qhia cov roj av ua ntej rau hauv cov tshuaj tiv thaiv chamber thiab ua rau nws muaj tshuaj lom neeg nyob rau hauv qhov kub thiab txias los tsim cov yeeb yaj kiab uas tau tso rau ntawm lub substrate. CVD thev naus laus zis yog dav siv los tsim cov khoom siv semiconductor, cov yeeb yaj kiab kho qhov muag, thiab cov txheej txheem uas tiv taus qhov kub thiab txias thiab tshuaj lom neeg corrosion.
3. Electroplating ua
Electroplating yog txheej txheem electrochemical los ntawm kev tso ib zaj duab xis nyias ntawm cov hlau lossis hlau rau ntawm qhov chaw ua haujlwm. Nyob rau hauv cov txheej txheem no, lub workpiece ua hauj lwm raws li ib tug cathode thiab muab tso rau hauv ib tug electrolyte uas muaj hlau ions. Thaum xa ncaj qha tam sim no, cov hlau ions raug txo rau ntawm qhov chaw ntawm lub workpiece los tsim cov yeeb yaj kiab hlau tsis sib xws. Nws yog tsuas yog siv los txhim kho cov tsos, tiv thaiv corrosion thiab hnav tsis kam ntawm hlau workpieces, nrog rau kev txhim kho hluav taws xob conductivity. Nws yog dav siv nyob rau hauv tsheb, electronics, aviation thiab lwm yam lag luam.
4. Thermal txau
Thermal spray thev naus laus zis tsim cov txheej txheem los ntawm cov khoom siv cua sov mus rau lub xeev molten lossis semi-molten thiab txau rau ntawm qhov chaw substrate ntawm kev kub ceev. Nws yog tsim rau txheej daim ntaub ntawv nyob rau hauv high kub, siab hnav thiab tshwj xeeb chemical ib puag ncig.
5. Txoj kev Sol-gel
Ib lub tshuab siv tshuaj lom neeg los npaj cov yeeb yaj kiab nyias ntawm cov substrates. Nws yog tsuas yog siv los npaj cov yeeb yaj kiab kho qhov muag, ceramic txheej, thiab lwm yam.
FANMETAL tuaj yeem muab cov phiaj xwm txhuas, lub hom phiaj chromium, lub hom phiaj titanium, lub hom phiaj molybdenum thiab lwm lub hom phiaj alloy. Yog tias tsim nyog, thov koj xav tiv tauj peb los ntawm email.
