Hejuru ceramisation

Hejuru ceraramisasiyo - plasma gutera no kwiyanga synthesis yubushyuhe
Plasma Spraing itanga DC ARC hagati ya Cathode na Anode. Arc ionie gaze ikora mubushyuhe bwinshi. Ikipe ya Plasma yashizweho kugirango ishonge ifu kugirango ikore ibitonyanga. Umuvuduko mwinshi wa gazi watoboye urumoto hanyuma ukabiburira substrate. Ubuso bukora. Ibyiza byimibare ya plasma ni uko ubushyuhe butera hejuru cyane, ubushyuhe bwo hagati burashobora kugeraho hejuru ya 10 000 K, hamwe nubushyuhe bwihuse bwo gushonga, kandi ipfundo rifite ubucucike nimbaraga nziza. Ibibi nuko uburyo bwiza bwo gutera hejuru. Hasi, kandi bihenze, ibiciro byishoramari rimwe biri hejuru.

Kwiyamamaza kwiyamamaza-ubushyuhe bwo hejuru (shs) ni tekinoroji yo guhuza ibikoresho bishya no kwikorera imiti myinshi yubushyuhe bukabije hagati ya reaction. Ifite ibyiza byibikoresho byoroshye, inzira yoroshye, umusaruro mwinshi, gukoresha ingufu nke kandi ntamwahumanya. Ni tekinoroji yubuhanga bukwiye cyane kurinda urukuta rwimbere rwimiyoboro. Umurongo wa Ceramic wateguwe na SHS ufite ibiranga imbaraga zihurira, gukomera kwinshi hamwe no kurwanya ibicuruzwa, bishobora kwagura neza ubuzima bwumuyoboro. Ikintu nyamukuru gigize ceramic cyakoreshejwe muburyo bwa peteroli ni fe + al2o3. Inzira ni yo kuvanga ifu ya crow haxide hamwe nifu ya aluminium mumuyoboro muremure, hanyuma ikazenguruka umuvuduko mwinshi ku kinya centrifuge, hanyuma itwika ku kigo cy'amashanyarazi, kandi ifu iraka. Igisubizo cyo kwimurwa kibaho kugirango ukore igice cya feri + al2o3. Igice cyashongejwe cyashyizwe mubikorwa byingufu za centrifugal. FE iri hafi y'urukuta rw'imbere rw'umuyoboro w'icyuma, kandi al2o3 ikora ikintu cy'imbere ceramic kure y'urukuta rw'umuyoboro.
