Ni ubuhe buryo bwo kurwanya okiside yibigize ceramic? Ni mu buhe buryo ibi ari ngombwa cyane?

Oxidation irwanya ibice bya ceramic byuzuye nibidukikije
Ibikoresho bya ceramic byuzuye nibintu byingenzi byingirakamaro cyane mubikorwa byinganda zigezweho, kandi imiterere yihariye yumubiri nubumashini yazanye impinduka zimpinduramatwara mubice byinshi. Muri byo, kurwanya okiside ni kimwe mu bintu bigaragara biranga ibice bigize ceramic, bifite akamaro kanini mu bidukikije bikabije.
Oxidation irwanya ibice bya ceramic byuzuye
Ibikoresho byiza bya ceramic, nka alumina, nitride ya silicon, karbide ya silicon, nibindi, bizwiho kuba byiza birwanya antioxydeant. Ibi bikoresho birashobora kugumana imiterere ihamye yimiti munsi yubushyuhe bwinshi hamwe nubushyuhe bwo hejuru bwa okiside, kandi ntabwo byoroshye kubyitwaramo na ogisijeni, bityo birinda okiside, kwangirika no kwangirika kwimikorere yibikoresho. Uku kurwanya okiside nziza cyane cyane biterwa nuburyo butajegajega bwa kirisiti hamwe nimbaraga za chimique imbere mubikoresho bya ceramic, bigatuma ibasha gukomeza umutekano muremure no kwizerwa mubidukikije bikaze.
Ibidukikije byingenzi
1. Ikirere
Mu kirere cyo mu kirere, kurwanya okiside yibikoresho bya ceramic byuzuye ni ngombwa cyane. Moteri yindege hamwe nicyogajuru bigomba kwihanganira ubushyuhe bwo hejuru cyane hamwe na gaze ya okiside mugihe cyo kuguruka byihuse. Ibigize nk'ibyumba byo gutwika, nozzles na turbine bikozwe mu bikoresho bya ceramique neza birashobora gukomeza imikorere ihamye ku bushyuhe bwo hejuru, bikarinda neza okiside na ruswa, kandi bigakora imikorere isanzwe ya moteri n’icyogajuru.
Urwego rw'ingufu
Mu rwego rwingufu, kurwanya okiside yibintu bya ceramic byuzuye nabyo bigira uruhare runini. Kurugero, mubikoresho byubushyuhe bwo hejuru nka gaz turbine hamwe n’amashyanyarazi akoreshwa n’amakara, ibice nkibikoresho byo gutwika amashyuza hamwe nayunguruzo bikozwe mubikoresho byubutaka birashobora kurwanya isuri yumwotsi wubushyuhe bwo hejuru, kurinda imiterere yimbere yibikoresho no kuzamura ingufu. Byongeye kandi, mu bijyanye n’ingufu za kirimbuzi, ibikoresho bya ceramique neza na byo bikoreshwa cyane mu kubika amashyuza no kurinda ibyuma bya kirimbuzi kugira ngo ingufu za kirimbuzi zikoreshwe neza.
Inganda zikora imiti
Mu nganda zikora imiti, ibintu byinshi byimiti nibikorwa bigomba gukorwa mubushyuhe bwinshi, umuvuduko mwinshi hamwe nibidukikije byangirika. Ibikoresho bya ceramic byuzuye, hamwe nibyiza byo kurwanya okiside hamwe no kurwanya ruswa, ni ibikoresho byingirakamaro muri ibi bidukikije. Kurugero, mubikoresho bya chimique bifite aside ikabije na alkali yangirika, ibice nkimiyoboro, indangagaciro na pompe bikozwe mubikoresho byubutaka birashobora gukumira neza kwangirika no kumeneka, bikarinda umutekano n’umutekano w’umusaruro w’imiti.
umwanzuro
Muri make, kurwanya okiside yibikoresho bya ceramic byuzuye ni kimwe mubintu byiza byayo byiza, bigira uruhare runini mu kirere, ingufu n’inganda. Hamwe niterambere ryiterambere rya siyanse nikoranabuhanga hamwe no kwaguka kwinshi mubikorwa, antioxydeant yibintu bya ceramic precision bizakomeza guhangayikishwa no kunozwa, bizana udushya niterambere mubice byinshi. Mu bihe biri imbere, hamwe niterambere rihoraho ryubumenyi bwibikoresho nubuhanga bwo gutegura, dufite impamvu zo kwizera ko ibice bya ceramic byuzuye bizerekana ubwiza bwihariye nagaciro kayo mubice byinshi.
