1. Thevacuum evaporation coatinginzira ikubiyemo guhumeka ibikoresho bya firime, gutwara atome ziva mumyuka mwinshi, hamwe na nucleation no gukura kwa atome ziva kumyuka hejuru yakazi.
2. Impanuka ya vacuum igipimo cya vacuum evaporation coating ni kinini, muri rusange 10-510-3Pa. Inzira yubusa ya molekile ya gaze ni 1 ~ 10m itondekanya ubunini, ikaba iruta kure cyane intera iva mumyuka iva mukigero cyakazi, iyi ntera yitwa intera ihumeka, muri rusange 300 ~ 800mm.Ibice bitwikiriye ntibishobora guhura na molekile ya gaze na atome ziva mu kirere kandi bigera ku kazi.
3. Icyuka cya vacuum coating layer ntabwo ari ugukomeretsa ibikomere, kandi atome ziva mumyuka zihita zijya kumurimo munsi ya vacuum.Gusa uruhande rwerekeranye nisoko yumwuka kurupapuro rwakazi rushobora kubona urwego rwa firime, kandi uruhande ninyuma yibikorwa ntibishobora kubona urwego rwa firime, kandi urwego rwa firime rufite plaque mbi.
4. Ingufu zuduce duto twa vacuum evaporation coating layer ni nkeya, kandi ingufu zigera kumurimo nimbaraga zubushyuhe zitwarwa numwuka.Kubera ko igihangano kidafite aho kibogamiye mugihe cyo gutwika vacuum, atome yicyuma yishingikiriza gusa ku bushyuhe bwo guhumeka mugihe cyo guhumeka, ubushyuhe bwuka ni 1000 ~ 2000 ° C, kandi ingufu zitwarwa zingana na 0.1 ~ 0.2eV, bityo ingufu za ibice bya firime ni bike, imbaraga zihuza hagati ya firime na matrix ni nto, kandi biragoye gukora igifuniko.
5. Icyuka cya vacuum igifuniko gifite imiterere myiza.Igikoresho cyo guhumeka cya vacuum gikozwe munsi yumuvu mwinshi, kandi uduce twa firime mumyuka mubyinshi mubipimo bya atome, bikora intangiriro nziza hejuru yumurimo.
