1. Atomization: Qhov no yog ib txoj hauv kev zoo tshaj plaws rau kev npaj cov hmoov txhuas. Molten hlau yog tawg mus rau hauv me me tee dej los ntawm siab - cov pa roj los yog kua, uas yog sai sai txias thiab solidified ua hmoov. Atomization tuaj yeem muab faib ua roj atomization thiab dej atomization. Gas atomization feem ntau yields hmoov nrog zoo dua sphericity, thaum dej atomization tsis tshua kim tab sis ua rau ntau cov duab tsis zoo.
2. Mechanical Alloying: Txoj kev no siv siab - lub zog pob milling los sib xyaw cov hmoov hlau sib txawv thiab rov ua kom txias dua - vuam thiab tawg, thaum kawg ua tiav atomic- qib alloying. Mechanical alloying tuaj yeem tsim cov tshuab tshwj xeeb alloy uas nyuaj rau kev siv cov txheej txheem, xws li supersaturated solid solutions lossis amorphous alloys.
3. Chemical Reduction: Txoj kev no siv tshuaj lom neeg los txo cov hlau sib txuas rau cov hmoov hlau. Txoj kev no tsim nyog rau kev npaj cov hmoov hlau hlau tsis zoo thiab tso cai rau kev tswj xyuas cov hmoov cov tshuaj muaj pes tsawg leeg thiab particle loj.
4. Electrolysis: Txoj kev no tau txais cov hlau deposits los ntawm electrolyzing hlau ntsev tov, uas yog ces ua tiav kom tau cov hmoov hlau alloy. Electrolysis tsim cov hmoov nrog siab purity tab sis siv ntau lub zog.
